Intermetallics and reflow profile

Electronics Forum | Tue May 02 15:29:14 EDT 2000 | M. F. Roe

I am looking for public papers or articles on intermetallic formation as a function of reflow profile. Most solder paste vendors specify peak temperature and time above liquidus, but I am particularly interested in what happens to intermetallic grow

MF: I know of nothing that addresses your question directly. Let me suggest: * Technical types at your solder supplier should be able to help. * "Effect Of Intermetallic Compounds On The Thermal Fatigue Of Surface Mount Solder Joints" PL Tu, et a

Are there profilers that I can use over my leaded and lead-free wave that can also profile my reflow ovens (leaded and lead-free). I'm not that familiar with either but as I learn I can't help but think that there should be something on the market t

Yeah, perhaps lean more towards a ramp-to-spike profile - reducing the soak time and add a littel heat to your temp above liquid. This has worked for us with water soluable paste as we are not required to use no-clean and utilizing a 6-zone oven. G
