四、保存和焊接條件(Storage & Soldering Conditions):
1、 注意保存,保存條件不好時,會降低膜片與反射殼(導光板)的粘附力。推薦保存條件為:溫度25℃&plun;10℃ 溫度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、 焊接溫度260℃&plun;5℃,焊接時間小于3秒,烙鐵功率小于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、 焊接點應離產品實體大于1.6mm.
The soldering point should be farther than 1.6mm form body.
4、注意靜電,戴有繩腕帶,工作臺上要有靜電墊,設備、儀器要接地,電烙鐵、錫爐、波峰焊要接地。
