1. 焊剂：溶剂包括N-甲基吡咯烷酮(NMP)或双甲对封装后框架外引脚的后处理可以是电镀(solder plating)或是浸锡(solder dipping)焊剂(flux)中进行浸泡,再放入熔融的焊锡中浸泡,最后用热水冲淋.
2. 助焊剂：浸锡也包括清洗工序,然后放到助 焊剂(flux)中进行浸泡,再放入熔融的焊锡中浸泡,最后用热水冲淋. 焊锡的成分一 般是63Sn/37Pb. 这是一种低共融合金,其熔点在183-184℃之间. 也有用成分为85Sn/ 15Pb、90Sn/10Pb、95Sn/5Pb的,
3. 熔剂：该组合物含有热可固化的树脂体系,包括至少一种环氧树脂和含酚的化合物如苯酚或酚醛树脂,作为催化剂的咪唑-酸酐加合物,和助熔剂(flux)的掺混物. 各种添加剂,如脱气剂,流动添加剂,粘合促进剂和流变改性剂也可以根据需要来添加.
4. 通量：不过目前LED发展照明应用还有诸多问题必须考虑,同时牵涉到规范标准以及散热、光学、电力设计,包括色温(CT)、通量(Flux)、光形(Distribution)等,且LED光源的颜色也十分重要,如停车场采用冷白光LED光源,将可降低人们犯罪频率.
The flux and reflux of the nations which fought and wandered in the countries.
