四、保存和焊接条件(Storage & Soldering Conditions):
1、 注意保存,保存条件不好时,会降低膜片与反射壳(导光板)的粘附力。推荐保存条件为:温度25℃&plun;10℃ 温度65℃&plun;20℃
Store with care. Storing the units in bad conditions will cause the reflector sheet and decrease it’s Adhive power. Storage the products under the Conditjon:temperature (25℃&plun;10℃) and humidity(65℃&plun;20℃ ORH) our recommendation.
2、 焊接温度260℃&plun;5℃,焊接时间小于3秒,烙铁功率小于30W。
The Soldering tempwrature is260℃&plun;5℃ and Soldering Time should be ls than 3 sec, and soldering iron power should be ls than 30W.
3、 焊接点应离产品实体大于1.6mm.
The soldering point should be farther than 1.6mm form body.
4、注意静电,戴有绳腕带,工作台上要有静电垫,设备、仪器要接地,电烙铁、锡炉、波峰焊要接地。
