陶瓷滤波器及无铅焊接

Ceramic Filter and Lead-free Soldering

国际上三大主要组织制定出自己的无铅标准这一国际背景,陶瓷滤波器作为一种必需的元件必须实现无铅化生产,着重介绍了陶瓷滤波器无铅焊接工艺:原材料(引线,陶瓷基片)的无铅化及焊接辅料(助焊剂,焊锡)无铅化;按工艺顺序详细介绍了浸焊锡、浸助焊剂、基片插入、正面焊接和反面焊接,并针对每一个工序的要求提出了可行的解决方案。最后分析了无铅化生产对国内陶瓷滤波器的影响。

The three main international organizations set up standard of Lead - free soldering. Ceramic Filter as a necessary componet must produce with Lead - free procedure. Introduce emphercisely Lead - free soldering process of Ceramic Filter： Lead - free raw material （ wire, ceramic substrate ） and soldering material （ Flux, Solder） ; According to the process introduce the dip soldering, dip fluxing, insertion of the substrate, right side soldering, back side soldering, give the feasible solution to each of the in detail. Analyze the effect of Lead - free to the domestic Ceramic Filter production. procedure
