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

It is one of our pastes...Almit LFM48 W TM-HP, a high reliability no clean solder paste based on SAC305 with a size 4 powder. It's a paste that works so well we have thousands of users of it worldwide. Why are you using SN100C alloy paste ? I imagin

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

Yup! All the major players out there - KIC, Datapaq, and ECD - are all capable of profiling both reflow and wave solder. check them out. www.kicthermal.com www.ecd.com www.datapaq.com

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

U may check your profile ramp rate. The flux may evporated and look like cold joint

proper pad geometries, accurate placement, and good reflow profile. Are you having problems right now?
