Does anyone have experience with using Pb-free SAC105? We are looking at the pro's/con's compared to a SAC305 process for a SMT operation. I have read it has a higher melting temperature. Specifically, we are concerned about a product we are developi

Hi, I would be interested to hear the outcome of your trials! Although, if mechanical stress is of concern, I would look at what is causing the stress and tackle that. I would suspect that any stress great enough to fracture sAC305 joint would do t

What is the different between SAC and LF Solder Alloys?I found out that LF38 is SAC105 and LF45 is SAC305. Is it because LF is some standard international name for particular country?
