IBM, Endicott, New York did extensive research on that. There was also some information I think that was published. You may want to contact Howard Manko of Manko & Associates. He's the soldering guru and has written many books on soldering & solderab

I am researching articles with respect to intermetalics growth associated with gold as a final metalization. We are currently looking at a few options that include a 10uin flash followed by a 30uin selective and a total 30uin finish. The concern is

Your research is on track. NC flux needs to reach activation temperature. Also, do not depend on the corrosion characteristics associated with the flux classification (ie, L1, L0, M1, M0, etc.), until the flux is activated by exposure to soldering

I don�t know much about zinc either. I can tell you that zinc forms no intermetallics with lead. So, I�m not so sure that �diffusion� is the correct term. Of the following: * Hwang "Modern Solder Technology For � * Wassink "Soldering In Electronic

Hi Everyone, We plan to build, for reliability/experimental/research purpose some CSPs (namely Tessera microBGA 46-I/O 0/75mm pitch and TI 64 I/O 0/8 mm pitch). the various factors that we plan to evaluate are the reliability and assembly concerns fo

Thanks for the response Dave This whole lead free joke gives me ulcers Compare the findings in the real world (threads in this forum) with the conclusions from the lead free industry counsel. The SAC305 is announced the "alloy of choice" here's a li

hi everybody, We've been doing some studies on assembly of CSPs. We assembled these packages on micrivia-in-pad patterns. These are 15/13.5/11 mil pads with 6 mil design microvia, using photo/laser/plasma tech. We are seeing voids, as big as the micr

Hi aj, We recently purchased an AOI machine. While doing the first pass research to see which machines to put through a head to head competition I discovered a major improvement in the programming for newer machines. If you buy used, get one that
