Abstract
This paper shows the dififculties of production, process the various technical by analyzing and contrasting the difference of the internal structure between the TO-220FS package and general product. And then by analyzing the causes of technical difficulties and taking the corresponding solutions, the technical difficulties are overcome smoothly. The process including process conditions, technology, equipment modiifcation, solve the problem of solder thickness control, eliminate stress in wire process, plastic pinhole, drunker, tendon pull in trimming process, isolation testing etc, the mass production successfully achieved.关键词
