I have a layer of electroplated solder (10/90) that appeares to have some sort of contaminent on it. Water will not wet to the layer in some areas. I have tried using 10% HCl in DI as a cleaner as well as 7.5% Fluoboric acid in DI. Neither has tou

Recently, one of our new vendor supplied us PCBs with Electroplated Nickel and Gold. We have the other regular source giving us ENIG plating. In both the wirebonding quality is OK. How do we benchmark this? Which one is suitable for production with l

Our vendor proposed to supply us with shields made out of Cold Rolled Steel (CRS) electroplated with Sn (50 - 150 minches). Should I be concerned with solderability or are there a better alternatives to tin finish?

Hi Everyone Does anyone has any insight regarding the void formation in the solderbumps during wafer bumping by electroplating. Someone told me that it could be mainly coz of the alloy concentration being incorrect. Any suggestions, corrective action

I am curious to hear feedback on whether companies that could benefit from a AuSn solder plating process would prefer to bring it inhouse (ie. License) or outsource the plating. I look forward to your comments. Bryan Smith Micralyne www.goldtinsold
