注意事项Cautions

(1) 焊接条件Soldering Conditions

    本产品 只可回焊两次,且在 回焊后须冷却至室温之后方可进行第二次回焊. 

Number of reflow process shall be less than 2 times and cooling process to normal temperature is required between first and Second soldering process.

焊盘式样(Recommended Soldering Pattern) 单位:毫米( Units:mm)

 

(2)静电 Static Electricity

  触摸LED时, 使用防静电手腕带或防静电手套.

It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs.

所有装置、设备、机器均应接地.

All devices, equipment and machinery must be properly grounded.

静电损坏的LED会显示出异常特征:正向电压变低或在低电流时死灯.标准: IF=0.5mA时, VF > 2.0V

Damaged LEDs will show some unusual characteristics such as the forward voltage becomes lower,: (VF > 2.0V    at    IF=0.5mA)

 (3)防潮包装Moisture Proof Package

使用防潮包装

It is recommended that moisture proof package be used .

 

 

(4)储藏Storage

   打开包装袋之前,LED在温度为30°C或 低湿度70%RH以下,可保存一年.

   Before opening the package ,The LEDs should be kept at 30°C or less and 70%

 used within a year.

 

 

（5）打开包装之后,应在24hrs内焊接完毕.

 After opening the package, The LEDs should be soldered within 24 hours (1days), they should be stored in moisture proof packages, such as sealed containers with packages of moisture absorbent material (silica gel).

 

 

下列情况发生时，须要在焊接前重新烘烤60 ± 5°C,24小时以上。

A．当包装袋破损漏气

B．打开包装后在24hrs内未焊接完毕

C．LED超过存储时间。.

If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the storage time, baking treatment should be performed using the following conditions Baking treatment : more than 24 hours at 65 ± 5°C.

 

 

(6)发热性Heat Generation

   高温会降低产品的性能及可靠性,请远离发热源.

High temperature reduces device performance &.

最终产品的散热设计是 重要的因素.系统设计时请考虑LED产生的热量.
