Comparing 62Sn/36Pb/2Ag with 63Sn/37Pb, addition of 2% Ag introduces two major advantages. The first advantage is grain refining, and the resultant better fatigue resistance. The second advantage is a wider processing window on Ag metallization. Pres

Any reason why you would switch to Immersion Ag from ENIG? I am also considering the use of Immersion Ag (switching from good ol 63/37). Are there any papers on the benifits/problems of ENIG vs Immersion Ag?? Thanks in advance JD
