SAC 305 Reflow & SN100C Wave and Selective | 15 February, 2007

Is there anybody out there doing this scenario:

SAC 305 Reflow & SN100C Wave and Selective

Can the 2 alloys be mixed on 1 board, say, SAC 305 for SMT, and SN100C for thru-hole? Are 2 different rework chemistries needed, or can one use SN100c wire or SAC 305 wire and touch up either type of joint?

Thanks in advanced.

They are all compatible with each other. Data is at alpha metals website and FCT assembly

Russ is correct. We have been using SAC 305 for SMT and SN100C for wave and selective and repair for about a year. May switch to SN100C in SMT at some point if we can get some paste that wets better.

We have been using SAC 305 for reflow and Cobalt 995 (very similar to SN100C, only cheaper) for wave and rework for quite a while now with no issues that I'm aware of.
