Leaded and Lead-Free Solder Paste Evaluation Screening Procedure

Leaded and Lead-Free Solder Paste Evaluation Screening Procedure

Numerous studies have shown that greater than 60% of end of line defects in SMT assembly can be traced to solder paste and the printing process. Reflowing adds another 15% or so. In light of this fact, it is surprising that no simplified procedure for solder paste evaluation has been documented. This paper is about such a procedure.
