ON Semiconductor SO8FL包装说明说明书
AND8195/DBoard Mounting Notes for SO8−Flat LeadPrepared by: Steve St. Germain, Phil Celaya, and Isauro Amaro ON SemiconductorINTRODUCTIONVarious ON Semiconductor devices are packaged in an advanced power leadless package named Quad FlatNo−Lead (QFN) Package. The power QFN platform represents the latest in surface mount packaging technology.It is important that the design of the Printed Circuit Board(PCB) and the assembly process follow the suggested guidelines outlined in this document.SO8FL Package OverviewThe SO8FL package was created to allow a larger MOSFET die to fit into a standard SO8IC footprint. This package uses a lead frame design that allows the leads to stick out beyond the molded body size. This feature allows the customer to see the solder fillet during visual inspection. See Figure 1 below.Figure 1. The Underside of an SO8FL Package Figure 2 illustrates how the package height is reduced to a minimum by having both die and wire bond pads on the same plane. When mounted, the leads and the body are directly attached to the board without a space−consuming standoff which is inherent in a leaded package.Figure 2 also illustrates how the ends of the leads go past the edge of the molded package. This configuration allows for the maximum die size within a given footprint, which in turn maximize the board space utilization.Figure 2. Cross−Section of SO8FL PackageIn addition to these features, the SO8FL package has excellent thermal dissipation and reduced electrical parasitic elements due to its efficient and compact design. Printed Circuit Board Design Considerations SMD and NSMD Pad ConfigurationsThere are two different types of PCB pad configurations commonly used for surface mount QFN style packages. These different I/O configurations are:1.Non Solder Masked Defined (NSMD)2.Solder Masked Defined (SMD)As their titles describe, the NSMD contact pads have the solder mask pulled away from the solderable metallization, while the SMD pads have the solder mask over the edge of the metallization, as shown in Figure 3. With the SMD pads, the solder mask restricts the flow of solder paste to the top of the metallization preventing the solder from flowing along the sides of the metal pad. This is different from the NSMD configuration where the solder will flow around both the top and the sides of the metallization.Figure 3. Comparison of NSMD vs. SMD PadsNSMD SMDSolder MaskOpeningSolderablePad OverlayAPPLICATION NOTETypically, the NSMD pads are preferred over the SMD configuration since defining the location and size of the copper pad is easier to control than the solder mask. This is based on the fact that the copper etching process is capable of a tighter tolerance than the solder masking process.In addition, the SMD pads will inherently create a stress concentration point where the solder wets to the pad on top of the lead. This stress concentration point is eliminated when the solder is allowed to flow down the sides of the leads in the NSMD configuration.NSMD Pad ConfigurationsWhen it is dimensionally possible, the solder mask should be located at least "0.076 mm (0.003 in) away from the edge of the solderable pad. This spacing is used to compensate for the registration tolerances of the solder mask, as well as to insure that the solder is not inhibited by the mask as it reflows along the sides of the metal pad.The dimensions of the PCB’s solderable pads should be larger than the device footprint to allow for visual inspection of solder filet. This is shown in Figure 4. The ratio between the package’s pad configuration, and that of the PCB’s, is designed for optimal placement accuracy and reliability.SO8FL Package FootprintSO8FL PCB PatternFigure 4. Printed Circuit Board Layout Using Non−Solder Masked Defined I/O PadsSO8FL Board Mounting ProcessThe surface mount process is optimized by first defining and controlling the following processes:1.Creating and maintaining a solderable metallization on the PCB contacts.2.Choosing the proper solder paste.3.Screening/stenciling the solder paste onto the PCB.4.Placing the package onto the PCB.5.Reflowing the solder paste.6.Final solder joint inspection.Recommendations for each of these processes are located below.PCB Solderable MetallizationThere are two common plated solderable metallization finishes which are used for PCB surface mount devices. In either case, it is imperative that the plating is uniform,conforming, and free of impurities to insure aconsistent solderable system.The first metallization finish consists of an Organic Solderability Preservative (OSP) coating over the copper plated pad. The organic coating assists in reducing oxidation in order to preserve the copper metallization for soldering.The second recommended solderable metallization finish consists of plated electroless nickel over the copper pad, followed by immersion gold. The thickness of the electroless nickel layer is determined by the allowable internal material stresses and the temperature excursions the board will be subjected to throughout its lifetime. Even though the gold metallization is typically a self−limiting process, the thickness should be of at least 0.05 m m thick, and not consist of more than 5% of the overall solder volume. Having excessive gold in the solder joint, can create gold embitterment, which may affect the reliability of the joint. Solder TypeSolder paste such as Cookson Electronics’ P/N WS3060 with a Type 3 or smaller sphere size is recommended. The WS3060 has a water−soluble flux for cleaning. Cookson Electronics’ P/N C0106A can be used if a no−clean flux is preferred.For lead free solders Sn−Ag−Cu, the following alloy (Sn 94.5%, Ag 4.5%, Cu .5%) paste is preferred.Solder Screening onto the PCBStencil screening the solder onto the PCB board is commonly used in the industry. The recommended stencil thickness used is 0.075 mm to 0.127 mm (0.003 in to 0.005 in) and the sidewalls of the stencil openings should be tapered approximately 5° to facilitate the release of the paste when the stencil is removed from the PCB.For a typical edge PCB terminal pad, the stencil opening should be the same size as the PCB mounting pad. However, in cases where the device pad is soldered to the PCB, the stencil opening must be divided into smaller cavities as shown in Figure 5. Dividing the larger pads into smaller screen openings reduces the risk of solder voiding and allows the solder joints for the smaller terminal pads to be at the same height as the larger ones. Typical solder coverage is 60 to 80% of exposed pad area.Package Placement onto the PCBPick and place equipment with the standard tolerance of "0.05 mm or better is recommended. The package will tend to center itself and correct for slight placement errors during the reflow process due to the surface tension of the solder.SO8FL RecommendedStencil PatternFigure 5. Solder stencil design illustrating how stencil openings are divided into an array for large die pads.Solder ReflowOnce the package is placed on the PC board along with the solder paste, a standard surface mount reflow process can be used to mount the part. Figures 6 and 7 are examples of standard reflow profiles for typical Tin/Lead solder and Lead−free solder alloys. Note the S08FL is qualified to meet Pb−free profile requirements per JEDEC Specification J−STD−020C.A recommended profile is available by the manufacturer of the paste since the chemistry and viscosity of the flux matrix will vary. The exact profile will be determined by the Process Engineer based on board density and thickness.These variations will require small changes in the profile in order to achieve an optimized process.TIME (sec)T E M P E R A T U R E (°C )Figure 6. Typical Reflow Profile for StandardTin/Lead SolderTIME (sec)T E M P E R A T U R E (°C )Figure 7. Typical Reflow Profile for StandardPb−Free SolderIn general, the temperature of the part should be raised not more than 25C/sec during the initial stages of the reflow profile. The soak zone then occurs when the part is approximately 1505C and should last for 60 to 180 seconds for Pb−free profiles (30−120 sec for SnPb profiles).Typically, extending the time in the soak zone will reduce the risk of voiding within the solder. The temperature is then raised and will be above the liquidus of the solder for 60 to 150 seconds for Pb−free profiles (30−100 sec for SnPb profiles) depending on the mass of the board. The peak temperature of the profile should be between 245 and 2605C for Pb−free solder alloys (205−2255C for SnPb solders).If required, removal of the residual solder flux can be completed by using the recommended procedures set forth by the flux manufacturer.Final Solder InspectionThe inspection of the solder joints is commonly performed with the use of an X−ray inspection system. With this tool, one can locate defects such as shorts between pads,open contacts, voids within the solder as well as any extraneous solder.In addition to searching for defects, the mounted device should be rotated on its side to inspect the sides of the solder joints with an X−ray inspection system. The solder joints should have enough solder volume with the proper stand−off height so that an “Hour Glass” shaped connection is not formed as shown below in Figure 7. “Hour Glass” solder joints are a reliability concern and must be avoided.Undesirable “Hour Glass’’Solder JointFigure 8. Side view of QFN attachment illustrating preferred and undesirable solder joint shapesRework ProcedureDue to the fact that the SO8FL is a leadless device, the entire package must be removed from the PC board if there is an issue with the solder joints. It is important to minimize the chance of overheating neighboring devices during the removal of the package since the devices are typically in close proximity with each other.Standard SMT rework systems are recommended for this procedure since the airflow and temperature gradients can be carefully controlled. It is also recommended to place the PC board in an oven at 125°C for 4 to 8 hours prior to heating the parts to remove excess moisture from the packages. In order to control the region which will be exposed to reflow temperatures, the board should be heated to 100_C by conduction through the backside of the board in the location of the SO8FL. Typically, heating nozzles are then used, to increase the temperature locally.Once the SO8FL solder joints are heated above their liquidus temperature, the package is quickly removed and the pads on the PC board need to be cleaned. The cleaning of the pads is typically performed with a blade−style conductive tool and with a de−soldering braid. A no−clean flux is used during this process in order to simplify the procedure.Solder paste is then deposited or screened onto the site in preparation of mounting a new device. Due to the close proximity of the neighboring packages in most PC board configurations, a miniature stencil for the individual component is typically required. The same stencil design that was originally used to mount the package can be applied to the mini−stencil for redressing the pad.Due to the small pad configurations of the SO8FL, and since the pads are on the underside of the package, a manual pick and place procedure without the aid of magnification is not recommended. A dual image optical system where the underside of the package can be aligned to the PC board should be used instead.Reflowing the component onto the board can be accomplished by either passing the board through the original reflow profile, or by selectively heating the SO8FL with the same process that was used to remove it. The benefit with subjecting the entire board to a second reflow is that the SO8FL will be mounted consistently and by a profile that is already defined. The disadvantage is that all of the other devices mounted with the same solder type will be reflowed for a second time. If subjecting all of the parts to a second is either a concern or unacceptable for a specific application, than the localized reflow option would be the recommended procedure.ON Semiconductor and are registered trademarks of Semiconductor Components Industries, LLC (SCILLC).

Turning the hex socket in a clockwise direction increases the beam downtilt below the horizon. Turning the hex socket in an anti-clockwise direction decreases the beam downtilt below the horizon. Beam downtilt setting in degrees below boresight can be read off the scale at the base of the antenna. The downtilt setting is read from the face of the antenna base plate at the point where the scale protrudes.AISG Compliant Remotely Adjustable Downtilt Antennas AISG Compliant antennas are compatible with AISG compliant control unit equipment. For operation of downtilt using AISG compliant controllers see the controller documentation.WARNING:During downtilt adjustment ensure the hex socket is not turned past the minimum and maximum positions as shown on the downtilt indicator scale. Forcing the hex adjustment beyond this point may lead to damage of the downtilt mechanism. Using power drillsand electric screwdrivers to adjust downtilt may also lead to damage of the downtilt mechanism.Port and Band IdentificationEach RF and/or AISG port on the antenna is numbered and identified in accordance with AISG Standard “AISG Antenna Port Color Coding .RemoteElectrical Tilt ConnectionThe AISG connector fitted to the antenna is designed to accept any AISG compliant cable assembly. After ensuring both connectors are dry, push in the mating connector, then tighten.Using excessive torque may damage the AISG connection in the antenna.RF Cable ConnectionThe RF female connectors fitted to the antenna are designed to fit jumper cables with corresponding male connector. After ensuring both mating connectors are dry push the male connector in and tighten to the correct torque setting.ADJUSTING MECHANICAL DOWN TILT AFTER INSTALLATIONT-125-GL, T-126-GL, T-128-GL & F-130-GL1. Use a tether to secure the antenna’s hoisting eye to the mountingstructure. The tether can be a rope, wire rope, chain, or similar material. The tether should be short enough to prevent the antenna from tilting beyond its maximum downtilt range. This will prevent the antenna from tilting away from the mounting structure when the adjusting bolts are removed.Installed cables or the antenna may be damaged if they are allowed to strike the mounting structure when the antenna mechanical downtilt is changed.Figure 17: Upper Mounting Bracket AssemblyA997-0096© 2016 CommScope, Inc.

din913
DIN9131. IntroductionDIN 913 is a standard for metric flat point set screws. Set screws are typically used to secure an object into place by exerting pressure against a surface. DIN 913 specifies the dimensions, tolerances, and requirements for flat point set screws in various sizes. This document provides an overview of the DIN 913 standard and its key features.2. ScopeThe scope of DIN 913 covers flat point set screws with various thread sizes, lengths, and materials. These set screws are designed to be used in applications requiring a flush surface without any protrusions. They are commonly used in machinery, automotive, and engineering industries.3. Dimensions and Tolerances3.1 Thread SizeDIN 913 specifies a range of thread sizes for flat point set screws, including M1.6, M2.5, M3, M4, M5, M6, M8, M10, M12, M16, M20, and M24. The thread size determines the compatibility of the set screw with the corresponding threaded hole.3.2 LengthThe length of the flat point set screw is measured from the bottom of the flat point to the end of the screw. DIN 913 provides standard lengths ranging from 6mm to 60mm, with increments of 1mm. The appropriate length should be selected based on the specific application and requirements.3.3 MaterialDIN 913 set screws can be manufactured from various materials such as stainless steel, carbon steel, and alloy steel. The choice of material depends on factors such as the application environment, required strength, and corrosion resistance.3.4 TolerancesThe tolerances for DIN 913 set screws are specified in accordance with DIN ISO 965-1 and DIN ISO 965-2 standards. These tolerances ensure the interchangeability and compatibility of set screws with corresponding components.4. Requirements4.1 StrengthDIN 913 requires set screws to meet certain strength requirements in order to ensure reliable and secure fastening. The strength of set screws is determined by factors such as the material used, thread size, and length.4.2 Flat PointThe flat point of the set screw is a critical feature as it ensures a flush contact against a surface without any protrusions. DIN 913 specifies the dimensions and tolerances for the flat point to ensure proper fit and performance.4.3 Surface FinishThe surface of DIN 913 set screws must be smooth and free from any defects that could affect their performance. The standard specifies the acceptable surface finish requirements to ensure the desired functionality and appearance.5. Marking and PackagingDIN 913 set screws should be marked with relevant information such as the manufacturer’s name or logo, thread size, material grade, and other pertinent details. This marking helps in identification and traceability. The set screws are typically packaged in boxes or bags with appropriate labeling for easy storage and handling.6. ConclusionThe DIN 913 standard provides essential guidelines for the manufacturing and use of metric flat point set screws. By defining the dimensions, tolerances, and requirements, DIN 913 ensures the consistent quality and compatibility of these set screws across different applications and industries. Adhering to this standard helps to guarantee the desired performance and safety of the fastening solution.。
CNC标准刀柄及拉钉
CNC刀柄标准加工中心的主轴锥孔通常分为两大类,即锥度为7:24的通用系统和1:10的HSK真空系统。
7:24锥度的通用刀柄锥度为7:24的通用刀柄通常有五种标准和规格,即NT(传统型)、DIN 69871(德国标准)、IS0 7388/1 (国际标准)、MAS BT(日本标准)以及ANSI/ASME(美国标准)。
NT型刀柄德国标准为DIN 2080,是在传统型机床上通过拉杆将刀柄拉紧,国内也称为ST;其它四种刀柄均是在加工中心上通过刀柄尾部的拉钉将刀柄拉紧。
目前国内使用最多的是DIN 69871型(即JT)和MAS BT 型两种刀柄。
DIN 69871型的刀柄可以安装在DIN 69871型和ANSI/ASME主轴锥孔的机床上, IS0 7388/1型的刀柄可以安装在DIN 69871型、IS0 7388/1 和ANSI/ASME主轴锥孔的机床上,所以就通用性而言,IS0 7388/1型的刀柄是最好的。
(1)DIN 2080型(简称 NT或ST)DIN 2080是德国标准,即国际标准ISO 2583 ,是我们通常所说NT型刀柄,不能用机床的机械手装刀而用手动装刀。
(2) DIN 69871 型(简称JT、 DIN、DAT或DV)DIN 69871 型分两种,即DIN 69871 A/AD型和DIN 69871 B型,前者是中心内冷,后者是法兰盘内冷,其它尺寸相同。
(3) ISO 7388/1 型(简称 IV或IT)其刀柄安装尺寸与DIN 69871 型没有区别,但由于ISO 7388/1 型刀柄的D4值小于DIN 69871 型刀柄的D4值,所以将ISO 7388/1型刀柄安装在DIN 69871型锥孔的机床上是没有问题的,但将DIN 69871 型刀柄安装在ISO 7388/1型机床上则有可能会发生干涉。
(4) MAS BT 型(简称 BT)BT型是日本标准,安装尺寸与 DIN 69871、IS0 7388/1 及ANSI 完全不同,不能换用。
