Relative Light Output vs Junction TemperaturePrecautions:Lead Forming:•The leads of an LED lamp may be preformed or cut to length prior to insertion and soldering on PC board.•For better control, it is recommended to use proper tool to precisely form and cut the leads to applicable length rather than doing it manually.•If manual lead cutting is necessary, cut the leads after the soldering process. The solder connection forms a mechanical ground which prevents mechanical stress due to lead cutting from traveling into LED package.This is highly recommended for hand solder operation, as the excess lead length also acts as small heat sink. Soldering and Handling:•Care must be taken during PCB assembly and soldering process to prevent damage to the LED component. •LED component may be e ectively hand soldered to PCB. However, it is only recommended under unavoid-able circumstances such as rework. The closest manual soldering distance of the soldering heat source (sol-dering iron’s tip) to the body is 1.59mm. Soldering the LED using soldering iron tip closer than 1.59mm might damage the LED.Note:1. PCB with di erent size and design (component density) will havedi erent heat mass (heat capacity). This might cause a change in temperature experienced by the board if same wave soldering setting is used. So, it is recommended to re-calibrate the soldering pro le again before loading a new type of PCB.Avago Technologies LED con gurationNote: Electrical connection between bottom surface of LED die andthe lead frame is achieved through conductive paste.•ESD precaution must be properly applied on the sol-dering station and personnel to prevent ESD damageto the LED component that is ESD sensitive. Do refer toAvago application note AN 1142 for details. The solder-ing iron used should have grounded tip to ensure elec-trostatic charge is properly grounded.•Recommended soldering condition:Wave Soldering [1, 2]Manual Solder DippingPre-heat temperature105 °C Max.-Preheat time60 sec Max-Peak temperature250 °C Max.260 °C Max.Dwell time 3 sec Max. 5 sec Max Note:1. Above conditions refers to measurement with thermocouplemounted at the bottom of PCB.2. It is recommended to use only bottom preheaters in order to reducethermal stress experienced by LED.•Wave soldering parameters must be set and main-tained according to the recommended temperature and dwell time. Customer is advised to perform daily check on the soldering pro le to ensure that it is always conforming to recommended soldering conditions.•Any alignment xture that is being applied during wave soldering should be loosely tted and should not apply weight or force on LED. Non metal material is rec-ommended as it will absorb less heat during wave sol-dering process.•At elevated temperature, LED is more susceptible to mechanical stress. Therefore, PCB must allowed to cool down to room temperature prior to handling, which in-cludes removal of alignment xture or pallet.•If PCB board contains both through hole (TH) LED and other surface mount components, it is recommended that surface mount components be soldered on the top side of the PCB. If surface mount need to be on the bottom side, these components should be soldered using re ow soldering prior to insertion the TH LED.•Recommended PC board plated through holes (PTH) size for LED component leads.LED componentlead size DiagonalPlated throughhole diameter0.45 x 0.45 mm(0.018x 0.018 inch)0.636 mm(0.025 inch)0.98 to 1.08 mm(0.039 to 0.043 inch)0.50 x 0.50 mm(0.020x 0.020 inch)0.707 mm(0.028 inch)1.05 to 1.15 mm(0.041 to 0.045 inch)•Over-sizing the PTH can lead to twisted LED after clinch-ing. On the other hand under sizing the PTH can cause di culty inserting the TH LED.Refer to Application Note 5334 for more information about soldering and handling of high brightness TH LED lamps.AlInGaP DeviceExample of Wave Soldering Temperature Pro le for TH LEDAmmo Packs DrawingALL DIMENSIONS IN MILLIMETERS (INCHES).NOTE:THE AMMO-PACKS DRAWING IS APPLICABLE FOR PACKAGING OPTION -DD &-ZZ AND REGARDLESS OF STANDOFF OR NON-STANDOFF.4025020015010050TIME (MINUTES)Recommended solder:Sn63(Leaded solder alloy)SAC305(Lead free solder alloy)Flux:Rosin fluxSolder bath temperature:245°C±5°C (maximum peak temperature =250°C)Dwell time:1.5sec -3.0sec (maximum =3sec)Note:Allow for board to be sufficiently cooled to room temperature before exerting T E M P E R A T U R E (°C )10mechanical force.Packaging Box for Ammo PacksPackaging Label(i) Avago Mother Label: (Available on packaging box of ammo pack and shipping box)FROM LEFT ADHESIVE FACING NOTE:THE DIMENSION FOR AMMO PACK IS APPLICABLE FOR THE DEVICE WITH STANDOFF AND WITHOUT STANDOFF.ONFor product information and a complete list of distributors, please go to our website: Avago, Avago Technologies, and the A logo are trademarks of Avago Technologies in the United States and other countries.Data subject to change.

可变式情报板与限速标志常见问题及解决方案
可变式情报板与限速标志常见问题及解决方案一：情报板常见问题及解决方案1.不能正常通信首先：检查通信线路是否正常，如线路故障请检测线路。
其次：如线路正常则检查工控机电源指示灯（复位按钮右侧）是否亮，不亮时测量工控电压是否正常（5V），电压不足或无电压时检查电源线连接是否正常（负极直接接电源，正极接控制板右下侧继电器），不正常则改正。
第三：工控机正常时检查工控机于控制板之间串口连接是否松动、脱落（连接不正常会导致工控机频繁重启进而导致不能正常通信），如有松动、脱落则改正。
第四：1：使用网络通信时检查网线是否插好，通信指示灯（网线插口左侧）是否正常，正常通信时绿色指示灯不停闪烁，网线连接正常而指示灯不亮时可用备用网口，更改网口需进入工控机修改网络IP，需专业人员操作。
2.1：使用串口通信时检查串口与浪涌保护器，浪涌保护器与串口之间连接是否正常，如有松动、脱落情况请改正，安装时请用螺丝上紧。
2.2:检查浪涌保护器是否正常，跳开浪涌保护器，把工控机串口直接连到光端机上，如通信正常则浪涌保护器损坏，更换浪涌保护器即可。
2.3：如浪涌保护器正常，则换用com3口试验一下，工控机默认通信串口com2（串口排线左侧带红边），备用串口com3（紧挨com2），都不能通信时需进入工控机检测串口是否正常，需专业人员操作。
2.4：如使用232-485转换器时还需检查转换器是否损坏。
第五：如更换工控机则需根据具体情况（屏体参数、IP、COM口等）进行调试，否则不能正常通信、显示，需专业人员操作。
2.情报板整屏不亮1.整屏不亮时请检查进电是否正常，2.进电正常时检查空气开关是否推上，如跳闸推上开关。
3.电压正常时检查控制板是否有电（红色电源指示灯是否亮），不亮时检查电源连接线是否松动、脱落。
4.没电时检查配电箱中5V电源是否正常。
5.检查控制板至输出板之间排线是否插好。
6.检查输出板电源指示灯是否亮，控制板正常而输出板电源指示灯不亮时更换输出板。
