Hi, I have a customer using leaded paste with lead free BGAs. I think they want to have the balls NOT collapse for better optical inspection. Sounds like a really bad idea to me but I have no explanation where I can say as why. Can anyone make suggestions either way? Thanks, Bob K. ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
