The WCPshall be identified for each socket.2. EQUIPMENT:Apparatus:2.1 TestThe apparatus for this test consists of an ESD pulse simulator and DUT socket. Figure 1 showsa typical equivalent HBM ESD circuit. Other equivalent circuits may be used, but the actualsimulator must be capable of supplying pulses that meet the waveform requirements of Table 1, Figure 2, and Figure 3.100 pFC1Terminal ATerminal BS1S2R11500 ohmHigh VoltagePulse GeneratorDUTsocketFigure 1: Typical Equivalent HBM ESD CircuitNotes:1.

Piggybacking of DUT sockets (the insertion of secondary sockets into the main DUT socket)is allowed only if the combined piggyback set (main DUT socket with the secondary DUT socket inserted) waveform meets the requirements of Table 1, Figure 2, and Figure 3. 6. Reversal of terminals A and B to achieve dual polarity is not permitted7. S2 should be closed 10 to 100 milliseconds after the pulse delivery period to ensure the DUTsocket is not left in a charged state. S2 should be opened at least 10 milliseconds prior to the delivery of the next pulse.2.2 Measurement Equipment:Equipment shall include an oscilloscope and current probe to verify conformance of the simulator output pulse to the requirements of this document as specified in Table 1, Figure 2, and Figure 3.2.2.1 Current Probe:The current probe shall have a minimum bandwidth of 350 Mhz and maximum cable length of 1 meter (Tektronix CT-1 or equivalent).2.2.2 Evaluation Loads:The two evaluation loads shall be: 1) a low inductance, 1000 volt, 500 ohm sputtered film resistor with + 1% tolerance, and 2) an 18 AWG tinned copper shorting wire.

AEC - Q101 - REV -May 15, 1996 Automotive Electronics CouncilComponent Technical CommitteeATTACHMENT 3AEC – Q101-003WIRE BOND SHEAR TESTAEC - Q101-003 - REV-AJuly 18, 2005 Automotive Electronics CouncilComponent Technical CommitteeMETHOD - 003DISCRETE COMPONENTWIRE BOND SHEAR TEST1. SCOPE:1.1 Description:This test establishes a procedure for determining the strength of the interface between a gold ball bond and a die bonding surface, or an aluminum wedge/stich bond and a die or package bonding surface, on either pre-encapsulation or post-encapsulation components. This strengthmeasurement is extremely important in determining two features:1) the integrity of the metallurgical bond which has been formed.2) the reliability of gold and aluminum wire bonds to die or package bonding surfaces.This test method can be used only when the ball height and diameter for ball bonds, or the wireheight (1.25 mil and larger at the compressed bond area) for wedge/stitch bonds, are largeenough and adjacent interfering structures are far enough away to allow suitable placement and clearance (e.g., above the bonding surface and between adjacent bonds) when performing thewire bond shear test.The wire bond shear test is destructive. It is appropriate for use in process development, process monitoring, and/or quality assurance.1.2 ReferenceDocuments:Not Applicable1.3 Terms and Definitions:The terms and definitions shall be in accordance with the following sections.1.3.1 BallBond:The welding of a thin wire, usually gold, to a die bonding surface, usually an aluminum alloy bond pad, using a thermal compression or thermosonic wire bonding process. The ball bond includes the enlarged spherical portion of the wire (sometimes referred to as the nail head and formed by the flame-off and first bonding operation in thermal compression and thermosonic process),theunderlying bonding surface, and the intermetallic weld interface. For the purposes of thisdocument, all references to ball bonds are applicable to gold ball bonds on die bonding surfaces;other ball bond material combinations may require a new set of failure criteria (see section 4.1).1.3.2 Bonding Surface:Either 1) the die surface (e.g., die bond pad) or 2) the package bonding surface (e.g., platedleadframe post or finger, downbond to the flag or paddle, etc.) to which the wire is ball, wedge, or stitch bonded.1.3.3 Bond Shear:A process in which an instrument uses a chisel shaped tool to shear or push a ball orwedge/stitch bond off the bonding surface (see Figure 1). The force required to cause thisseparation is recorded and is referred to as the bond shear strength. The bond shear strength of a gold ball bond, when correlated to the diameter of the ball bond, is an indicator of the quality of the metallurgical bond between the gold ball bond and the die bonding surface metallization. The bond shear strength of an aluminum wedge/stitch bond, when compared to the manufacturer’s bond wire tensile strength, is an indicator of the integrity of the weld between the aluminum wire and the die or package bonding surface.Shear ToolhSpecimen ClampTest SpecimenBonding Bond Weld AreaBondC LSurfaceFigure 1: Bond Shear Set-up1.3.4 Definition of Bond Shear Types for Ball and Wedge/Stitch Bonds (see Figure 3):1.3.4.1 Type 1 - Bond Lift:A separation of the entire wire bond from the bonding surface with only an imprint being left on the bonding surface. There is very little evidence of intermetallic formation or welding to the bonding surface metallization.1.3.4.2 Type 2 - Bond Shear:A separation of the wire bond where: 1) A thin layer of bonding surface metallization remains with the wire bond and an impression is left in the bonding surface, or 2) Intermetallics remain on the bonding surface and with the wire bond, or 3) A major portion of the wire bond remains on the bonding surface.1.3.4.3 Type 3 - Cratering:A condition under the bonding surface metallization in which the insulating layer (oxide orinterlayer dielectric) and the bulk material (silicon) separate or chip out. Separation interfaceswhich show pits or depressions in the insulating layer (not extending into the bulk) are notconsidered craters. It should be noted that cratering can be caused by several factors includingthe wire bonding operation, the post-bonding processing, and even the act of wire bond sheartesting itself. Cratering present prior to the shear test operation is unacceptable.1.3.4.4 Type 4 - Die Surface Contact:The shear tool contacts the die surface and produces an invalid shear value. This condition maybe due to improper placement of the specimen, a die surface not parallel to the shearing plane, alow shear height, or instrument malfunction. This bond shear type is not acceptable and shall beeliminated from the shear data.1.3.4.5 Type 5 - Shearing Skip:The shear tool removes only the topmost portion of the ball or wedge/stich bond. This condition may be due to improper placement of the specimen, a die surface not parallel to the shearing plane, ahigh shear height, or instrument malfunction. This bond shear type is not acceptable and shall beeliminated from the shear data.1.3.4.6 Type 6 - Bonding Surface Lift:A separation between the bonding surface metallization and the underlying substrate or bulkmaterial. There is evidence of bonding surface metallization remaining attached to the ball orwedge/stich bond.1.3.5 Footprint:An impression of the compressed wedge/stitch bond area created in the bonding surface during the ultrasonic wire bonding process. The bond footprint area is normally larger than the actualmetallurgical weld interface.1.3.6 Shear Tool or Arm:A tungsten carbide, or equivalent, chisel with specific angles on the bottom and back of the toolto insure a shearing action.Bond:1.3.7 Wedge/StitchThe welding of a thin wire, usually aluminum, to a die or package bonding surface using anultrasonic wire bonding process. The wedge bond, sometimes referred to as a stitch bond,includes the compressed (ultrasonically bonded) area of the bond wire and the underlyingbonding surface. When wedge/stitch bonding to an aluminum alloy bonding surface, nointermetallic exists because the two materials are of the same composition; but rather the twomaterials are combined and recrystallized by the ultrasonic energy of the welding process. Forthe purposes of this document, all references to wedge/stich bonds are applicable to aluminumwedge/stich bonds only; gold wedge/stich bonds are not required to be wire bond shear tested.2. APPARATUS AND MATERIAL:The apparatus and materials required for wire bond shear testing shall be as follows:Equipment:2.1 InspectionAn optical microscope system or scanning electron microscope providing a minimum of 70Xmagnification.Equipment:2.2 MeasurementAn optical microscope or measurement system capable of measuring the wire bond diameter to within ± 0.1 mil.2.3 Workholder:Fixture used to hold the component being tested parallel to the shearing plane and perpendicular to the shear tool. The fixture shall also eliminate component movement during wire bond shear testing. If using a caliper controlled workholder, place the holder so that the shear motion isagainst the positive stop of the caliper. This is to insure that the recoil movement of the caliper controlled workholder does not influence the wire bond shear test.2.4 Wire Bond Shear Equipment:The wire bond shear equipment must be capable of precision placement of the shear toolapproximately 0.1 mil above the topmost part of the bonding surface. This distance (h) shallinsure the shear tool does not contact the die or package bonding surface and shall be less than the distance from the topmost part of the bonding surface to the center line (C L) of the ball orwedge/stich bond.2.5 Bond Shear Tool:Required shear tool parameters include but are not limited to: flat shear face, sharp shearingedge, and shearing width of 1.5 to 2 times (1.5X to 2X) the bond diameter or bond length. Theshear tool should be designed so as to prevent plowing and drag during wire bond shear testing.The shear tool should be clean and free of chips (or other defects) that may interfere with thewire bond shear test.3. PROCEDURE:3.1 Calibration:Before performing the wire bond shear test, it must be determined that the equipment has been calibrated in accordance with the manufacturer's specifications and is presently in calibration.Recalibration is required if the equipment is moved to another location.3.2 Visual Examination of Wire Bonds to be Shear Tested After Decapsulation:Before performing wire bond shear testing on a component which has been opened using wetchemical and/or dry etch techniques, the bonding surfaces shall be examined to insure there isno absence of metallization on the bonding surface area due to chemical etching and wire bonds are attached to the bonding surface. Ball or wedge/stitch bonds on bonding surfaces withevidence of degradation from chemical attack or absence of metallization shall not be used forwire bond shear testing. Wire bonds on bonding surfaces without degradation from chemicalattack may not be attached to the bonding surface due to other causes (e.g., package stress).These wire bonds are considered valid and shall be included in the shear data as a zero (0) gram value. Wire bonds must also be examined to ensure adjacent interfering structures are farenough away to allow suitable placement and clearance (above the bonding surface andbetween adjacent wire bonds) when performing the wire bond shear test.Sizes:3.3 SampleThe sample size shall be as specified in Table 1 of CDF-AEC-Q101.3.4 Measurement of the Ball Bond Diameter to Determine the Ball Bond Failure Criteria:Once the bonding surfaces have been examined and prior to performing wire bond shear testing, the diameter of all ball bonds (from at least one representative sample to be tested) shall bemeasured and recorded. For asymmetrical ball bonds, determine the average using both thelargest (d large) and the smallest diameter (d small) values (see Figure 2). These ball bonddiameter measurements shall be used to determine the mean, or average, diameter value. The resulting mean, or average, ball bond diameter shall then be used to establish the failure criteria as defined in section 4.1. If process-monitor data has established the nominal ball bonddiameter, then that value may be used to determine the failure criteria as defined in section 4.1.SYMMETRICAL ASYMMETRICALFigure 2: Ball Bond Diameter Measurement (symmetrical vs. asymmetrical)3.5 Wire Bond Shear Test Procedure:The wire bond shear testing procedure shall be performed as follows:a. The wire bond shear equipment shall pass all self diagnostic tests prior to performing thewire bond shear test.b. The wire bond shear equipment and test area shall be free of excessive vibration ormovement. Examine the shear tool to verify it is in good condition and is not bent ordamaged. Check the shear tool to verify it is in the up position.c. Adjust the workholder to match the component being tested. Secure the component tothe workholder. Make sure the die or package bonding surface is parallel to the shearingplane of the shear tool. It is important that the shear tool does not contact the bondingsurface or adjacent structures during the shearing operation as this will give incorrect highreadings.d. Position the component so that the wire bond to be tested is located adjacent to theshear tool. Lower the shear tool (or raise the component depending upon wire bondshear equipment used) to approximately the die or package bonding surface but notcontacting the surface (approximately the thickness of the wire bond above the die orpackage bonding surface).e. For ball bond shear testing, position the ball bond to be tested so that the shear motionwill travel perpendicular to the die edge. Wire bond shear testing is required for ballbonds located at the die bonding surface interface only.f. For aluminum wedge/stitch bond shear testing, a wire height at the compressed bondarea of 1.25 mils and larger is required. For wires too small for wire bond shear testing(less than 1.25 mils in height at the compressed bond area), only a footprint inspection isrequired (see section 3.7). Position the wedge/stitch bond to be tested so that the shearmotion will travel toward the long side of the wedge/stitch bond and is free of anyinterference (i.e. shear the outside wedge/stitch bond first and then shear toward thepreviously sheared wedge/stitch bond). Wire bond shear testing is required for aluminumwedge/stitch bonds located at die and package bonding surfaces; gold wedge/stichbonds are not required to be wire bond shear tested.g. Position the shear tool a distance of approximately one ball bond diameter (or onealuminum wire diameter for wedge/stitch bonds) from the wire bond to be shear testedand shear the wire bond.3.6 Examination of Sheared Wire Bonds:All wire bonds shall be sheared in a planned/defined sequence so that later visual examinationcan determine which shear values should be eliminated due to an improper shear. The wirebonds shall be examined using at least 70X magnification to determine if the shear tool skippedover the wire bond (type 5) or the shear tool scraped or plowed into the die surface (type 4). See Figure 3 for bond shear types and illustrations.Readings in which either a bond shear type 4 or 5 defective shear condition occurred shall beeliminated from the shear data. Bond shear type 1, 2, 3, and 6 shall be considered acceptableand included in the shear data.Sheared wire bonds in which a bond shear type 3 cratering condition has occurred shall beinvestigated further to determine whether the cracking and/or cratering is due to the wire bonding process or the act of wire bond shear testing. Cratering caused prior to the wire bond shear test operation is unacceptable. Cratering resulting from the act of wire bond shear testing shall beconsidered acceptable and included in the shear data.3.7 Footprint Inspection of Aluminum Wedge/Stitch Bonds:a. All aluminum wire bonding processes to both die and package bonding surfaces shallhave a bond footprint inspection performed.b. For wires too small for wire bond shear testing (less than 1.25 mils in height at thecompressed bond area), the wires shall be removed at the wedge/stitch bond locationusing a small sharp blade to peel or pluck the wire bond from the bonding surface. Theremoval of the aluminum wire shall be sufficient such that the wire bond interface can bevisually inspected and the metallurgical wire bond area determined.c. For larger wires (greater than 1.25 mils in height at the compressed bond area), the wiresshall be inspected after wire bond shear testing to examine the failure mode and todetermine the wedge/stitch bond footprint coverage.3.8 Bond Shear Data:Data shall be maintained for each wire bond sheared. The data shall identify the wire bond(location, ball bond and/or wire diameter, wire material, method of bonding, and material bonded to), the shear strength, and the bond shear type (as defined in section 1.3.4 and Figure 3).CRITERIA:4. FAILUREThe following failure criteria are not valid for components that have undergone environmentalstress testing or have been desoldered from circuit boards.4.1 Failure Criteria for Gold Ball Bonds:The gold ball bonds on a component shall be considered acceptable if the minimum individualand sample average ball bond shear values are greater than or equal to the values specified inFigure 4 and Table 1. This criteria is applicable for gold wire ball bonds on aluminum alloybonding surfaces. Other material combinations may require a new set of failure criteria.Alternate minimum ball bond shear values may be proposed by the supplier if supporting datajustifies the proposed minimum values.4.2 Failure Criteria for Wedge/Stitch Bonds:The aluminum wedge/stitch bonds on a component shall be considered acceptable if theminimum shear values are greater than or equal to the manufacturer’s bond wire tensile strength.In addition, the percent of the wedge/stitch bond footprint in which bonding occurs shall begreater than or equal to 50%. If it is necessary to control the wire bonding process using SPC for percent coverage, a C pk value can be calculated to this limit.Figure 3: Wire Bond Shear Types ** (Shear types are illustrated using ball bonds; these types also apply to wedge/stitch bonds)MINIMUM SHEAR VALUESBALL BOND DIAMETER (mils)2.252.53.03.253.53.754.254.54.755.05.252.0S H E A R S T R E N G T H (g r a m s )1.750102030405060708090100110 2.754.0Figure 4: Minimum Acceptable Individual and Sample Average Ball Bond Shear Values *, seeTable 1 for exact ball bond shear values ** (Shear values are applicable for gold wire ball bonds on aluminum alloy bonding surfaces)Table 1: Minimum Acceptable Individual and Sample Average Ball Bond Shear Values * * (Shear values are applicable for gold wire ball bonds on aluminum alloy bonding surfaces)Ball Bond Diameter(mils)MinimumSample Average(grams)Minimum IndividualShear Reading(grams)2.012.6 5.72.1 14.0 6.8 2.2 15.5 8.1 2.3 17.1 9.5 2.4 18.8 10.9 2.5 20.6 12.4 2.6 22.4 14.0 2.7 24.4 15.6 2.8 26.5 17.42.9 28.6 19.23.0 30.8 21.1 3.1 33.2 23.1 3.2 35.6 25.1 3.3 38.1 27.2 3.4 40.7 29.4 3.5 43.4 31.7 3.6 46.2 34.1 3.7 49.1 36.5 3.8 52.1 39.13.9 55.2 41.74.0 58.3 44.3 4.1 61.6 47.1 4.2 65.0 50.0 4.3 68.4 52.9 4.4 71.9 55.8 4.5 75.6 59.0 4.6 79.3 62.1 4.7 83.1 65.3 4.8 87.0 68.64.9 91.0 72.05.0 95.1 75.5Revision HistoryRev #-A Date of changeMay 15, 1996July 18, 2005Brief summary listing affected sectionsInitial Release.Added new Section 1.3.5.

EQUIPMENT:2.1 Test Apparatus:The apparatus for this test consists of an ESD pulse simulator; Figure 1 shows a typicalequivalent CDM ESD circuit. Other equivalent circuits may be used, but the actual simulatormust be capable of supplying pulses that meet the waveform requirements of Table 2, Table 3, and Figure 3.(a) Direct charge CDM (b) Field induced charge CDM Note: Parasitics in the charge and discharge path of the test equipment can greatly affect test results Figure 1: Charged Device Model ESD Typical Equivalent Circuit for (a) Direct Charge and (b) Field Induced Charge2.2 Measurement Equipment:Equipment shall include an oscilloscope/digitizer, current probe, attenuators, andcable/connector assemblies to verify conformance of the simulator output pulse to therequirements of this document as specified in Table 2, Table 3, and Figure 3.2.2.1 Oscilloscope/Digitizer:The oscilloscope/digitizer shall have a minimum bandwidth of 1.0GHz and nominal inputimpedance of 50Ω (Tektronix SCD1000, HP 7104, or equivalent).2.2.2 Current Probe:The current probe shall be an inductive current transducer or coaxial resistive probe with aminimum bandwidth of 5GHz.2.2.3 Attenuator:The attentuator, if required, shall be high precision (+0.1dB precision at 1.0GHz) with impedance of 50Ω.2.2.4 Cable/Connector Assembly:The cable/connector assembly, if required, shall be low loss (less than 0.4dB loss up to 1GHz) with impedance of 50Ω.2.2.5 Verification Modules:The two verification modules shall be gold-plated or nickel-plated etched copper disks on singlesided FR-4 material (thickness = 0.8mm). The disks shall be: 1) a small disk (diameterapproximately = 9 mm) configuration with a capacitance value of 4pF ±5% measured at 1MHz,and 2) a large disk (diameter approximately = 26mm) configuration with a capacitance of 30pF ±5% measured at 1MHz.

A period of one (1) year is the maximum permissible time between full calibration tests. Qualification of the CDM simulator must be performed during initial acceptance testing or after repairs that are made to theequipment that may affect the waveform. The simulator must meet the requirements of Table 2 and Figure 3 for five (5) consecutive waveforms at all voltage levels using the 4pF verificationmodule shown in Figure 2. Simulators not capable of producing the maximum voltage levelshown in Table 2 shall be qualified to the highest voltage level possible. The simulator must also meet the requirements of Table 3 and Figure 3 for five (5) consecutive waveforms at the 500 volt level using the 30pF verification module shown in Figure 2. Thereafter, the test equipment shall be periodically qualified as described above; a period of one (1) year is the maximum permissible time between full qualification tests.2.4 Verification Module Calibration:The capacitance value of verification modules can be dramatically degraded by excessive use (indentations due to repetitive pogo pin contact, cracks in metallization, warping, etc.).Therefore, to ensure proper capacitance values, it is recommended that module capacitancebe verified per section 2.4.1. When modules are degraded to the point they no longer meet the specified capacitance requirements shown in Table 1, they must be replaced.2.4.1 Verification Module Capacitance Measurement Procedure:a. Using the 4pF verification module, place the non-metallic side of the module in directcontact with the metallic surface of a ground plane. Capacitance measurements can beaffected by air gaps between the module and the ground plane (e.g., due to warping ofthe FR-4 material, etc.). Therefore, the air space between the module and the groundplane must be minimized. This can be accomplished by applying slight pressure usingthe capacitance meter probes; care must be taken to avoid damaging the diskmetallization.b. Using the capacitance meter defined in section 2.2.6, measure the capacitance of theverification module to the ground plane. The capacitance value shall meet therequirements defined in Table 1.c. Repeat steps (a) and (b) using the 30pF verification module.2.5 Simulator Waveform Verification:The performance of the simulator can be dramatically degraded by parasitics in the dischargepath. Therefore, to ensure proper simulation and repeatable ESD results, it is recommendedthat waveform performance be verified using the 4pF verification module. The waveformverification shall be performed prior to performing CDM testing. If at any time the waveforms do not meet the requirements of Table 2 and Figure 3 at the 500 volt level, the testing shall behalted until waveforms are in compliance.2.5.1 Waveform Verification Procedure:a. Prior to performing waveform verification, verification modules and tester components(e.g., pogo pin, charge plate, etc.) must be cleaned with isoproponal (isopropyl alcohol)using a procedure approved by the user’s internal safety organization. Once clean,avoid direct skin contact. If handling is required, the use of vacuum tweezers orpersonnel finger cots is strongly recommended.b. Place the 4pF verification module in direct contact with the charge plate of the CDMsimulator. If a dielectric film is used during component testing, it shall be less than 130microns thick and must be in place during the waveform verification procedure.c. Set the horizontal time scale of the oscilloscope at 0.5 nanoseconds per division orless.d. Raise the charge plate potential to positive 500 volts. With the discharge pin centeredwithin the 4pF metallic disk, bring the discharge pin in direct contact with theverification module and initiate a discharge.e. Measure and record the rise time, first peak current, second peak current, third peakcurrent, and full width at half height. All parameters must meet the limits specified inTable 2 and Figure 3.f. Raise the charge plate potential to negative 500 volts. With the discharge pin centeredwithin the 4pF metallic disk, bring the discharge pin in direct contact with theverification module and initiate a discharge.g. Measure and record the rise time, first peak current, second peak current, third peakcurrent, and full width at half height. All parameters must meet the limits specified inTable 2 and Figure 3.Table 2: CDM Waveform Specification for 4pF Verification ModuleVoltage Level (V) 1st peakcurrentfor 4pFI p1(A)(±20%)2nd peakcurrentfor 4pFI p2(A)3rd peakcurrentfor 4pFI p3(A)RiseTimet r(ps)Full width at half heightfor 4pFFWHH(ps)250 2.25 < 50% ofI p1 < 25% ofI p1< 400 < 600500 4.50 < 50% ofI p1 < 25% ofI p1< 400 < 6001000 9.00 < 50% ofI p1 < 25% ofI p1< 400 < 6002000 18.00 < 50% ofI p1 < 25% ofI p1< 400 < 600Table 3: CDM Waveform Specification for 30pF Verification ModuleVoltage Level (V)1st peakcurrentfor 30pF *I p1 (A)(±20%)2nd peakcurrentfor 30pF *I p2(A)3rd peakcurrentfor 30pF *I p3(A)RiseTimeT rfor 30pF *(ps)Full width at half heightfor 30pF *FWHH(ps)500 14.00 < 50% of I p1 < 25% of I p1 < 400 < 1000* The 30pF verification module is used only during Equipment Qualification as specified in section 2.3.90%10%50%C u r r e n t i n A m p e r e sTime in nanoseconds0.5 1.0 1.5 2.00.0Figure 3: Typical CDM Current Waveform3. PROCEDURE: 3.1 Sample Size:Each sample group shall be composed of ten (10) components per stress voltage level. Each sample group shall have all component pins and/or terminals (including power and ground pins) stressed at one (1) voltage level, following the test flow diagram of Figure 4. Each stress voltage level requires a new sample group of ten (10) components.3.2 Charging and Discharging Methods:There are two acceptable methods of charging a DUT: Direct Charging and Field-induced Charging. Either method may be used to perform CDM ESD testing and must be recorded. While several methods exist for discharging a DUT, the direct contact discharge method is the only acceptable method to discharge a DUT for this test method.3.2.1 Direct Charging Method:The DUT is placed “dead-bug” (upside down with pins and/or terminals pointing up) withcomponent body in direct contact with the charge plate and charged either through the pin(s) providing the best ohmic connection to the substrate of the DUT or through all DUT pinssimultaneously (see Figure 1). To prevent damaging the DUT, ensure both the component and charging mechanism are at ground potential prior to initiating the CDM test. Contact to thecharging pin(s) must be made prior to raising the charge potential. Once the DUT is charged, a pin under test (PUT) is discharged (except any pin(s) directly connected to the substrate of theDUT). It is permissible to leave the charging probe in direct contact with the charging pin during the discharge event provided the discharge waveform meets the requirements of Table 2, Table 3, and Figure 3. After discharging the PUT, the DUT shall be re-charged and the process isrepeated for each pin to be tested. All charge pins must be recorded.3.2.2 Field-induced Charging Method:The DUT is placed “dead-bug” (upside down with pins and/or terminals pointing up) withcomponent body in direct contact with the field charging plate and charged by raising the potential of the charge plate (see Figure 1). To prevent damaging the DUT, ensure both the componentand charge plate are at ground potential prior to initiating the CDM test. Once the DUT ischarged, a pin under test (PUT) is discharged. After discharging the PUT, the DUT shall be re-charged and the process is repeated for each pin to be tested. The field charging plate shall be at least seven times (7X) larger in area than the DUT and shall meet the requirements of Table 2,Table 3, and Figure 3. If a dielectric film is used during component testing, it shall be less than130 microns thick and must be in place during the waveform verification procedure.3.2.3 Charging Small Components:Small component packages may not be able to hold enough charge to meet the specifieddischarge voltage levels. For these packages, perform the test once and, if there is insufficientcharge, the supplier must instead perform both HBM and MM ESD testing. The supplier shalldocument that the package could not hold sufficient charge to perform the CDM ESD test.3.2.4 Direct Discharging Method:Direct contact discharge is initiated within a relay and can add parasitics to the discharge path(care must be taken to minimize these parasitics). A discharge probe (e.g., pogo pin),connected to the relay, is placed in direct contact with the PUT and produces a very repeatableCDM event.3.3 Test Temperature:Each component shall be subjected to ESD pulses at room temperature.3.4 Measurements:Prior to ESD testing, complete parametric testing (initial electrical verification) shall beperformed on all sample groups and all components in each sample group per applicable userdevice specification at room temperature followed by hot temperature, unless specifiedotherwise in the user device specification. A data log of each component shall be made listingall parameter measurements as defined in Table 4. The data log will be compared to theparameters measured during final electrical verification testing to determine the failure criteriaof section 4.3.5 Cleaning Method:To avoid charge loss during CDM testing, components should be cleaned with isopropanol(isopropyl alcohol) using a procedure approved by the local safety organization. Componentsshould then be handled only by vacuum tweezers, personnel wearing finger cots or equivalent, or plastic tweezers which have been neutralized by holding in an ionized air stream. The CDM tester should be cleaned periodically with isopropanol (isopropyl alcohol) to remove any surfacecontamination that could result in charge loss. Particular attention should be paid to the discharge probe, charging probe, and the charge plate on which the component is placed.3.6 Detailed Procedure:The ESD testing procedure shall be per the test flow diagram of Figure 4 and as follows:a. Place clean DUT “dead-bug” (upside down with pins and/or terminals pointing up) withcomponent body in direct contact with the charge plate.b. Follow the recommended test flow diagram of Figure 4.c. Select a charging method and charge the DUT to a positive potential.d. Select a PUT and discharge the DUT. After discharging, wait a minimum of 1 secondand re-charge the DUT. The use of three (3) discharges at each charge voltage polarityis required.e. Set the charge voltage to a negative potential.f. Repeat steps (c) through (d) using the same PUT.g. Repeat steps (b) through (f) until every PUT (all component pins and/or terminals) isdischarged at the specified voltage.h. Test the next component in the sample group and repeat steps (a) through (g) until allcomponents in the sample group have been tested at the specified voltage level.i. Submit the components for complete parametric testing (final electrical verification) perthe user device specification at room temperature followed by hot temperature, unlessspecified otherwise in the user device specification, and determine whether thecomponents meet the failure criteria requirements specified in section 4. It is permittedto perform the parametric testing (final electrical verification) per user devicespecification after all sample groups have been tested.j. Using the next sample group, select the next stress voltage level as specified in Figure 4 and repeat steps (a) through (i).k. Repeat steps (a) through (j) until failure occurs or the component fails to meet the 125 volt stress voltage level.4. FAILURE CRITERIA:A component will be defined as a failure if, after exposure to ESD pulses, the component fails anyof the following criteria:1. The component exceeds the allowable shift values for the specific key parameters listedin Table 4. Other component parameters and allowable shift values may be specified inthe user device specification. During initial parametric testing, a data log shall be madefor each component listing the applicable parameter measurement values. This data logwill be compared to the parameters measured during final parametric testing to determinethe shift value. Components exceeding the allowable shift value will be defined as afailure.2. The component no longer meets the user device specification requirements. Completeparametric testing (initial and final electrical verification) shall be performed per applicableuser device specification at room temperature followed by hot temperature, unlessspecified otherwise in the user device specification.Table 4: Key Parameters and Allowable Shift ValuesComponent Type Parameters Maximum Allowable Shift Values Bipolar I CES, I CBO, and I EBO Ten times (10X) the initialmeasurementFET I DSS and I GSS Ten times (10X) the initialmeasurementIGBT I CES and I GES Ten times (10X) the initialmeasurementDiode I R Ten times (10X) the initialmeasurement5. ACCEPTANCE CRITERIA:A component passes a voltage level if all components stressed at that voltage level and belowpass. All the samples must meet the measurement requirements specified in section 3 and thefailure criteria requirements specified in section 4. Using the classification levels specified inTable 5, the supplier shall classify the components according to the maximum withstandingvoltage level. Due to the complex nature of the CDM event, a change in manufacturing process, design, materials, or component package may require reclassification according to this testmethod.Table 5: Discrete Component CDM ESD Classification LevelsComponent ClassificationMaximum Withstand VoltageC0 ≤ 125 V C1 > 125 V to ≤ 250 V C2 > 250 V to ≤ 500 V C3 > 500 V to ≤750 V C4 > 750 V to ≤ 1000 VC5> 1000 VFigure 4: Discrete Component CDM ESD Test Flow DiagramRevision HistoryRev #- Date of changeJuly 18, 2005Brief summary listing affected sectionsInitial Release.。

AEC-Q101标准的试验项目包括了温度循环试验、湿热循环试验、热冲击试验、丈量温度试验、机械振动试验、冲击试验等。

下面分别介绍这些试验项目的判定标准。

温度循环试验是通过将元器件在高温和低温之间循环进行多次,检测元器件在温度变化下的性能和可靠性。

判定标准根据元器件的不同,通常分为三个级别:Level1、Level2和Level3。

Level1要求元器件在-40°C至125°C之间进行1000次温度循环,而Level3要求元器件在-40°C至125°C之间进行5000次温度循环。

温度循环试验的主要判定依据是元器件的电性能是否发生明显变化,如电阻、电容等是否在合理的范围内。

湿热循环试验是将元器件放置于高温高湿度环境中进行多次循环,以测试其在高湿度环境下的稳定性。

判定标准同样根据元器件的不同而有所不同。

例如,对于陶瓷电容器来说,AEC-Q101标准要求在40°C、93%相对湿度下循环1000次,判定标准是元器件的电容值变化是否超过一定范围。

热冲击试验是将元器件迅速放置于高温和低温之间,以测试其在温度变化冲击下的可靠性。

判定标准通常根据元器件的不同而有所不同。

以半导体器件为例,对于AEC-Q101标准中的Level1,要求元器件在-40°C和150°C之间进行1000次热冲击试验,判定标准是元器件的电性能是否发生明显变化。

This document may be freely reprinted with this copyright notice. This document cannot be changed without approval by the AEC Components Technical Committee.METHOD - 003DISCRETE COMPONENTWIRE BOND SHEAR TEST1. SCOPE:1.1 Description:This test establishes a procedure for determining the strength of the interface between a gold ball bond and a die bonding surface, or an aluminum wedge/stich bond and a die or package bonding surface, on either pre-encapsulation or post-encapsulation components. This strengthmeasurement is extremely important in determining two features:1) the integrity of the metallurgical bond which has been formed.2) the reliability of gold and aluminum wire bonds to die or package bonding surfaces.This test method can be used only when the ball height and diameter for ball bonds, or the wire height (1.25 mil and larger at the compressed bond area) for wedge/stitch bonds, are largeenough and adjacent interfering structures are far enough away to allow suitable placement and clearance (e.g., above the bonding surface and between adjacent bonds) when performing thewire bond shear test.The wire bond shear test is destructive. It is appropriate for use in process development, process monitoring, and/or quality assurance.Documents:1.2 ReferenceNot Applicable1.3 Terms and Definitions:The terms and definitions shall be in accordance with the following sections.Bond:1.3.1 BallThe welding of a thin wire, usually gold, to a die bonding surface, usually an aluminum alloy bond pad, using a thermal compression or thermosonic wire bonding process. The ball bond includes the enlarged spherical portion of the wire (sometimes referred to as the nail head and formed by the flame-off and first bonding operation in thermal compression and thermosonic process),theunderlying bonding surface, and the intermetallic weld interface. For the purposes of thisdocument, all references to ball bonds are applicable to gold ball bonds on die bonding surfaces;other ball bond material combinations may require a new set of failure criteria (see section 4.1).1.3.2 Bonding Surface:Either 1) the die surface (e.g., die bond pad) or 2) the package bonding surface (e.g., plated leadframe post or finger, downbond to the flag or paddle, etc.) to which the wire is ball, wedge, or stitch bonded.1.3.3 Bond Shear:A process in which an instrument uses a chisel shaped tool to shear or push a ball orwedge/stitch bond off the bonding surface (see Figure 1). The force required to cause thisseparation is recorded and is referred to as the bond shear strength. The bond shear strength of a gold ball bond, when correlated to the diameter of the ball bond, is an indicator of the quality of the metallurgical bond between the gold ball bond and the die bonding surface metallization. The bond shear strength of an aluminum wedge/stitch bond, when compared to the manufacturer’s bond wire tensile strength, is an indicator of the integrity of the weld between the aluminum wire and the die or package bonding surface.Shear ToolhSpecimen ClampTest SpecimenBondingBond Weld Area Bond C L SurfaceFigure 1: Bond Shear Set-up1.3.4 Definition of Bond Shear Types for Ball and Wedge/Stitch Bonds (see Figure 3):1.3.4.1 Type 1 - Bond Lift:A separation of the entire wire bond from the bonding surface with only an imprint being left on the bonding surface. There is very little evidence of intermetallic formation or welding to the bonding surface metallization.1.3.4.2 Type 2 - Bond Shear:A separation of the wire bond where: 1) A thin layer of bonding surface metallization remains with the wire bond and an impression is left in the bonding surface, or 2) Intermetallics remain on the bonding surface and with the wire bond, or 3) A major portion of the wire bond remains on the bonding surface.1.3.4.3 Type 3 - Cratering:A condition under the bonding surface metallization in which the insulating layer (oxide orinterlayer dielectric) and the bulk material (silicon) separate or chip out. Separation interfaceswhich show pits or depressions in the insulating layer (not extending into the bulk) are notconsidered craters. It should be noted that cratering can be caused by several factors includingthe wire bonding operation, the post-bonding processing, and even the act of wire bond sheartesting itself. Cratering present prior to the shear test operation is unacceptable.1.3.4.4 Type 4 - Die Surface Contact:The shear tool contacts the die surface and produces an invalid shear value. This condition maybe due to improper placement of the specimen, a die surface not parallel to the shearing plane, alow shear height, or instrument malfunction. This bond shear type is not acceptable and shall beeliminated from the shear data.1.3.4.5 Type 5 - Shearing Skip:The shear tool removes only the topmost portion of the ball or wedge/stich bond. This condition may be due to improper placement of the specimen, a die surface not parallel to the shearing plane, ahigh shear height, or instrument malfunction. This bond shear type is not acceptable and shall beeliminated from the shear data.1.3.4.6 Type 6 - Bonding Surface Lift:A separation between the bonding surface metallization and the underlying substrate or bulkmaterial. There is evidence of bonding surface metallization remaining attached to the ball orwedge/stich bond.1.3.5 Footprint:An impression of the compressed wedge/stitch bond area created in the bonding surface during the ultrasonic wire bonding process. The bond footprint area is normally larger than the actualmetallurgical weld interface.1.3.6 Shear Tool or Arm:A tungsten carbide, or equivalent, chisel with specific angles on the bottom and back of the toolto insure a shearing action.Bond:1.3.7 Wedge/StitchThe welding of a thin wire, usually aluminum, to a die or package bonding surface using anultrasonic wire bonding process. The wedge bond, sometimes referred to as a stitch bond,includes the compressed (ultrasonically bonded) area of the bond wire and the underlyingbonding surface. When wedge/stitch bonding to an aluminum alloy bonding surface, nointermetallic exists because the two materials are of the same composition; but rather the twomaterials are combined and recrystallized by the ultrasonic energy of the welding process. Forthe purposes of this document, all references to wedge/stich bonds are applicable to aluminumwedge/stich bonds only; gold wedge/stich bonds are not required to be wire bond shear tested.2. APPARATUS AND MATERIAL:The apparatus and materials required for wire bond shear testing shall be as follows:Equipment:2.1 InspectionAn optical microscope system or scanning electron microscope providing a minimum of 70Xmagnification.Equipment:2.2 MeasurementAn optical microscope or measurement system capable of measuring the wire bond diameter to within ± 0.1 mil.2.3 Workholder:Fixture used to hold the component being tested parallel to the shearing plane and perpendicular to the shear tool. The fixture shall also eliminate component movement during wire bond shear testing. If using a caliper controlled workholder, place the holder so that the shear motion isagainst the positive stop of the caliper. This is to insure that the recoil movement of the caliper controlled workholder does not influence the wire bond shear test.2.4 Wire Bond Shear Equipment:The wire bond shear equipment must be capable of precision placement of the shear toolapproximately 0.1 mil above the topmost part of the bonding surface. This distance (h) shallinsure the shear tool does not contact the die or package bonding surface and shall be less than the distance from the topmost part of the bonding surface to the center line (C L) of the ball orwedge/stich bond.2.5 Bond Shear Tool:Required shear tool parameters include but are not limited to: flat shear face, sharp shearingedge, and shearing width of 1.5 to 2 times (1.5X to 2X) the bond diameter or bond length. Theshear tool should be designed so as to prevent plowing and drag during wire bond shear testing.The shear tool should be clean and free of chips (or other defects) that may interfere with thewire bond shear test.3. PROCEDURE:3.1 Calibration:Before performing the wire bond shear test, it must be determined that the equipment has been calibrated in accordance with the manufacturer's specifications and is presently in calibration.Recalibration is required if the equipment is moved to another location.3.2 Visual Examination of Wire Bonds to be Shear Tested After Decapsulation:Before performing wire bond shear testing on a component which has been opened using wetchemical and/or dry etch techniques, the bonding surfaces shall be examined to insure there isno absence of metallization on the bonding surface area due to chemical etching and wire bonds are attached to the bonding surface. Ball or wedge/stitch bonds on bonding surfaces withevidence of degradation from chemical attack or absence of metallization shall not be used forwire bond shear testing. Wire bonds on bonding surfaces without degradation from chemicalattack may not be attached to the bonding surface due to other causes (e.g., package stress).These wire bonds are considered valid and shall be included in the shear data as a zero (0) gram value. Wire bonds must also be examined to ensure adjacent interfering structures are farenough away to allow suitable placement and clearance (above the bonding surface andbetween adjacent wire bonds) when performing the wire bond shear test.Sizes:3.3 SampleThe sample size shall be as specified in Table 1 of CDF-AEC-Q101.3.4 Measurement of the Ball Bond Diameter to Determine the Ball Bond Failure Criteria:Once the bonding surfaces have been examined and prior to performing wire bond shear testing, the diameter of all ball bonds (from at least one representative sample to be tested) shall bemeasured and recorded. For asymmetrical ball bonds, determine the average using both thelargest (d large) and the smallest diameter (d small) values (see Figure 2). These ball bonddiameter measurements shall be used to determine the mean, or average, diameter value. The resulting mean, or average, ball bond diameter shall then be used to establish the failure criteria as defined in section 4.1. If process-monitor data has established the nominal ball bonddiameter, then that value may be used to determine the failure criteria as defined in section 4.1.SYMMETRICAL ASYMMETRICALFigure 2: Ball Bond Diameter Measurement (symmetrical vs. asymmetrical)3.5 Wire Bond Shear Test Procedure:The wire bond shear testing procedure shall be performed as follows:a. The wire bond shear equipment shall pass all self diagnostic tests prior to performing thewire bond shear test.b. The wire bond shear equipment and test area shall be free of excessive vibration ormovement. Examine the shear tool to verify it is in good condition and is not bent ordamaged. Check the shear tool to verify it is in the up position.c. Adjust the workholder to match the component being tested. Secure the component tothe workholder. Make sure the die or package bonding surface is parallel to the shearingplane of the shear tool. It is important that the shear tool does not contact the bondingsurface or adjacent structures during the shearing operation as this will give incorrect highreadings.d. Position the component so that the wire bond to be tested is located adjacent to theshear tool. Lower the shear tool (or raise the component depending upon wire bondshear equipment used) to approximately the die or package bonding surface but notcontacting the surface (approximately the thickness of the wire bond above the die orpackage bonding surface).e. For ball bond shear testing, position the ball bond to be tested so that the shear motionwill travel perpendicular to the die edge. Wire bond shear testing is required for ballbonds located at the die bonding surface interface only.f. For aluminum wedge/stitch bond shear testing, a wire height at the compressed bondarea of 1.25 mils and larger is required. For wires too small for wire bond shear testing(less than 1.25 mils in height at the compressed bond area), only a footprint inspection isrequired (see section 3.7). Position the wedge/stitch bond to be tested so that the shearmotion will travel toward the long side of the wedge/stitch bond and is free of anyinterference (i.e. shear the outside wedge/stitch bond first and then shear toward thepreviously sheared wedge/stitch bond). Wire bond shear testing is required for aluminumwedge/stitch bonds located at die and package bonding surfaces; gold wedge/stichbonds are not required to be wire bond shear tested.g. Position the shear tool a distance of approximately one ball bond diameter (or onealuminum wire diameter for wedge/stitch bonds) from the wire bond to be shear testedand shear the wire bond.3.6 Examination of Sheared Wire Bonds:All wire bonds shall be sheared in a planned/defined sequence so that later visual examinationcan determine which shear values should be eliminated due to an improper shear. The wirebonds shall be examined using at least 70X magnification to determine if the shear tool skippedover the wire bond (type 5) or the shear tool scraped or plowed into the die surface (type 4). See Figure 3 for bond shear types and illustrations.Readings in which either a bond shear type 4 or 5 defective shear condition occurred shall beeliminated from the shear data. Bond shear type 1, 2, 3, and 6 shall be considered acceptableand included in the shear data.Sheared wire bonds in which a bond shear type 3 cratering condition has occurred shall beinvestigated further to determine whether the cracking and/or cratering is due to the wire bonding process or the act of wire bond shear testing. Cratering caused prior to the wire bond shear test operation is unacceptable. Cratering resulting from the act of wire bond shear testing shall beconsidered acceptable and included in the shear data.3.7 Footprint Inspection of Aluminum Wedge/Stitch Bonds:a. All aluminum wire bonding processes to both die and package bonding surfaces shallhave a bond footprint inspection performed.b. For wires too small for wire bond shear testing (less than 1.25 mils in height at thecompressed bond area), the wires shall be removed at the wedge/stitch bond locationusing a small sharp blade to peel or pluck the wire bond from the bonding surface. Theremoval of the aluminum wire shall be sufficient such that the wire bond interface can bevisually inspected and the metallurgical wire bond area determined.c. For larger wires (greater than 1.25 mils in height at the compressed bond area), the wiresshall be inspected after wire bond shear testing to examine the failure mode and todetermine the wedge/stitch bond footprint coverage.3.8 Bond Shear Data:Data shall be maintained for each wire bond sheared. The data shall identify the wire bond(location, ball bond and/or wire diameter, wire material, method of bonding, and material bonded to), the shear strength, and the bond shear type (as defined in section 1.3.4 and Figure 3).CRITERIA:4. FAILUREThe following failure criteria are not valid for components that have undergone environmentalstress testing or have been desoldered from circuit boards.4.1 Failure Criteria for Gold Ball Bonds:The gold ball bonds on a component shall be considered acceptable if the minimum individualand sample average ball bond shear values are greater than or equal to the values specified inFigure 4 and Table 1. This criteria is applicable for gold wire ball bonds on aluminum alloybonding surfaces. Other material combinations may require a new set of failure criteria.Alternate minimum ball bond shear values may be proposed by the supplier if supporting datajustifies the proposed minimum values.4.2 Failure Criteria for Wedge/Stitch Bonds:The aluminum wedge/stitch bonds on a component shall be considered acceptable if theminimum shear values are greater than or equal to the manufacturer’s bond wire tensile strength.In addition, the percent of the wedge/stitch bond footprint in which bonding occurs shall begreater than or equal to 50%. If it is necessary to control the wire bonding process using SPC for percent coverage, a C pk value can be calculated to this limit.Figure 3: Wire Bond Shear Types ** (Shear types are illustrated using ball bonds; these types also apply to wedge/stitch bonds)MINIMUM SHEAR VALUESBALL BOND DIAMETER (mils)2.252.53.03.253.53.754.254.54.755.05.252.0S H E A R S T R E N G T H (g r a m s )1.750102030405060708090100110 2.754.0Figure 4: Minimum Acceptable Individual and Sample Average Ball Bond Shear Values *, seeTable 1 for exact ball bond shear values ** (Shear values are applicable for gold wire ball bonds on aluminum alloy bonding surfaces)Table 1: Minimum Acceptable Individual and Sample Average Ball Bond Shear Values * * (Shear values are applicable for gold wire ball bonds on aluminum alloy bonding surfaces)Ball Bond Diameter(mils)MinimumSample Average(grams)Minimum IndividualShear Reading(grams)2.012.6 5.72.1 14.0 6.8 2.2 15.5 8.1 2.3 17.1 9.5 2.4 18.8 10.9 2.5 20.6 12.4 2.6 22.4 14.0 2.7 24.4 15.6 2.8 26.5 17.42.9 28.6 19.23.0 30.8 21.1 3.1 33.2 23.1 3.2 35.6 25.1 3.3 38.1 27.2 3.4 40.7 29.4 3.5 43.4 31.7 3.6 46.2 34.1 3.7 49.1 36.5 3.8 52.1 39.13.9 55.2 41.74.0 58.3 44.3 4.1 61.6 47.1 4.2 65.0 50.0 4.3 68.4 52.9 4.4 71.9 55.8 4.5 75.6 59.0 4.6 79.3 62.1 4.7 83.1 65.3 4.8 87.0 68.64.9 91.0 72.05.0 95.1 75.5Revision HistoryRev #-A Date of changeMay 15, 1996July 18, 2005Brief summary listing affected sectionsInitial Release.Added new Section 1.3.5.

組件技術委員會AEC 文件是为了服务于汽车电子工业,无论其标准是用在国内还是国际上,都可排除器件制造商和采购商之间方面的不一致性,推动产品的提高和可交换性,还能帮助采购商在最小的时间耽搁内选择和获得那些非 AEC 成员的合适的产品。

AEC 文件并不关注其采纳的内容是否涉及到专利、文章、材料或工艺。

AEC 没有认为对专利拥有者承担责任,也没有认为要对任何采用 AEC 文件者承担义务。

汽车电子系统制造商的观点主要是 AEC 文件里的信息能为产品的说明和应用提供一种很完美的方法。

如果所陈述的要求在本文件中不存在,就不能声称与本文件具有一致性。

基于离散半导体元件应力测试认证的失效机理組件技術委員會下列划线部分标示了与上版文件的增加内容和区别,几个图表也作了相应的修正,但是这几处的更改并没有加下划线强调。

除非这里另有说明,无论新认证或重认证,此标准的生效日期同上面的发布日期。

1.范围本文件包含了离散半导体元件(如晶体管,二极管等)最低应力测试要求的定义和参考测试条件.使用本文件并不是要解除供应商对自己内部认证项目的责任性,此外此文件并不解除供应商满足本文件范围外的任何文件需求。

其中的使用者被定义为所有按照规格书使用其认证器件的客户,客户有责任去证实确认所有的认证数据与本文件相一致。

1.1目的此規範的目的是要确定一种器件在应用中能够通过应力测试以及被认为能够提供某种级别的品质和可靠性。

1.2参考文件目前参考文件的修订将随认证计划协议的日期而受到影响,后续认证计划将会自动采用这些参考文件的更新修订版。

HBM 和CDM 涵盖几乎所有已知的 ESD 失效机理。

1.3定义1.3.1AEC Q101 认证如果成功完成根据本文件各要点需要的测试结果,那么将允许供应商声称他们的零件通过了AEC Q101 认证。

供应商可以与客户协商,可以在样品量和条件的认证上比文件要求的要放宽些,但是只有完成所有要求时候才能认为該器件通过了 AEC-Q101 认证。

如静电放电, 承受电压在任何一个供應商的帶 Pin 元件数据表中都要註明,該要求被高度推薦.但允许供应商作出聲明,例如,“AEC-Q101 qualified to ESD H1B”,这意味着除 AEC ESD 外,供应商通过了所有的测试。

请注意,即使合格的器件AEC 也不会颁发證書.根據本規範,离散半导体的最低温度的范围应为-40℃~ +125℃,所有 LED 的最小的范围应为40℃到85℃。

(注:某些器件最高溫度可能降到零)1.3.2应用承认承认被定义为客户同意在他们的应用中使用某零件,但客户承认的方式已经超出了本文件的范围1.3.3术语在本文中,“器件”是指“設備”或“组件”,如,單個二极管,晶体管,电阻等芯片封裝在塑膠模中並有連接到板端的引線.2通用要求組件技術委員會2.1优先要求当该标准中的要求与其他文件相冲突时,可采用以下优先顺序:。

a、采购订单b、個人同意的器件規範c、本文件标准d、本文件的 1.2 节中的参考文件e、供应商的数据规格本規範認為合格的器件,其採購訂單或特殊器件規格不能免除和偏離本文件的要求.2.2满足认证和重新认证要求的通用数据的使用使用通用数据来简化认证过程非常值得提倡,需要考虑到的是,通用数据必须基于一系列特殊要求:a.表2 中器件认证要求.b.表3 与每个零件的特性相关的具体要求矩阵和制造工艺c.附录 1 中的认证家族定义.d.有代表性的随机样本附录 1 定义了标准,通过它各个成员可以组成这个认证家族,为的是所有家族成员的数据对于质疑的器件认证都能是均等的和普遍接受的。

当关注这些认证家族的指导原则,就能够积累起适用于该家族其他器件的信息。

这些信息能够用来证实一个器件家族的通用可靠性并使特殊器件认证测试项目的需要减少到最低,这可以通过以下途径可以实现:认证和监测认证家族中最复杂的器件(例如高/低电压、极大/极小晶片),对后来加入此认证家族不太复杂的器件应用这些信息数据。

通用数据的来源应该是供应商经过鉴定的测试实验室,它包括内部供应商认证,客戶特殊认证,以及供应商过程监控。

提交的通用数据必须达到或超过表 2 中列出的测试条件。

表 1 提供的指南,表明部分合适的测试数据可用于减少很多认证要求. 特殊用户器件必须完成电气特性测试,通用性能数据在认证呈报时是不允许的。

使用者有最终权接受通用数据来代替测试数据。

表 1 零件认证和重新认证的批次要求表 2 定义了一组认证测试,须考虑新器件认证和设计或过程变化的重认证表 3 描述了一组必须考虑到器件有任何改变的认证测试,其中的矩阵图也同样描述了与制程改变相关的新工艺制程和重新认证。

该表是一个测试总括,使用者应将其作一个基本准则来讨论那些存在疑问需要认证的测试。

供应商有责任介绍为什么某些被推荐的测试不须要进行的基本原理。

2.4測試樣品2.4.1.批次要求批次要求在表 2 中有定義2.4.2生产要求所有认证器件都应在制造场所加工处理,有助于量产时零件的传输2.4.3测试样品的再利用性已被用于非破坏性测试的器件还可用来进行其它认证测试。

已被用于破坏性认证的器件,除工程分析外,不得再作他用。

2.4.4样品量要求样本用于测试和/或通用数据的提交必须符合指定的最小样品量和表 2 中的验收标准。

如果供应商选择使用通用数据来认证,则特殊的测试条件和结果必须记录.现有适用的通用数据应该首先被用来满足表 2 中的每个测试要求和 2.3 节中这些要求。

如果通用数据不能满足这些要求,应进行器件特定的认证测试.組件技術委員會#2#1證認 供应商必须执行待认证的特定器件或可接受的通用器件的任何组合,数量不少于 3 批次 x 77 片/批次.2.4.5 通用数据接受的时间限制只要从初始认证的所有可靠性数据被呈交给客户评估起,通用数据的可接受性就不存在时间上的限制,以下图表可作为可靠性数据的合适来源,此数据必须取自按照附录 1 定义的特殊器件或同样认证家族中的器件,包括任何客户的特殊数据(如果客户非 AEC ,保留客户的名字),制程认证改变,周期可靠性监控数据(见图 1)注:一些制程改变(如元件缩小化)将会影响通用数据的使用,以至于这些改变之前得到的数据就不能作为通用数据接受使用。
