What does the reflow profile look like , the question I had was surrounding the higher reflow temperature and the max temperature that lowest thermal mass components will see. Some other questions that I had were surrounding the components , what of

I have a product with mixed in Pb free and Pb BGAs. I decide to use SnPb paste with Pb free reflow profile to make it work for both types of BGA. Do I have a reliability solder joint issue by using this method? How is your opinion on this case? Can

So, it looks like the backward compatible of BGA statement is not guarantee for solder joint reliability. It doesn�t matter what temperature and what melting sequence we have in order to avoid the solder void issue. Is Pb diffused homogeneously thr

Yikes! Sounds like a hairy situation there. I've successfully collapsed a Pb-Free BGA (using a Sn/Pb solder paste), with a peak temperature of 220 Deg. C and Time Above SAC's Eutetic point (217) of 17 seconds. Beware of overcooking your smaller ma

Hello everyone, at the Institute for Manufacturing Automation and Production Systems of the University of Erlangen (Germany) one focus of our research activities is the use of lead-free solder alloys for electronics production. In different publicat

can you send me the articles about the high frequency boards issues with different types of solder paste alloy because i can`t find any free document about this article

Thank you Djo for your sharing. By the way, do you know that which field/product will prefer to use SAC405 paste instead of SAC305 or lower Ag wt% alloy solder paste?

Hi below is a link to a database set up that list the properties of all SAC alloys, worth reading. http://www.europeanleadfree.net/POOLED/DOCUMENTS/a178886/ELFNET_COST531_Solder_Alloy_Properties_Database_v1.pdf its from http://www.europeanleadfree.
