Abstract
It is in the special stage to transfer from lead solder to lead-free solder. The things such as lead-free material、PCB、component、examination and reliability have no common standard. In this paper, the actuality of lead-free solder and its characteristics and countermeasures are introduced in detail, otherwise, the main problems of lead-free solder and the problems when lead solder and lead-free solder were used together that should be paid attention to during the transfer stage are also analyzed entirely.
