The temp is not an issue with selective soldering as the SN100C can be used at the same temp we used for tin lead. 260C. Some are using a higher temp, we did not notice any difference in the results with a higher temp.
Most people run thier waves at 500F, thats 260C. Remember, the entire component does not hit that temp for extended time like in a reflow oven. We do not have our wave running yet with SN100C but I would think it would be fine at 500F. I will let you know in a week or two. What temp do you run at George?
Also, this may not be the subjet at hand but,
I have heard some people make comments that SN100C is only acceptable for low reliability/low cost applications and that SAC305 is the choice for high reliability. I have seen no data to support that at all. SN100C is less expensive, that does not mean it is less reliable. Lets keep in mind where we all came from, tin/lead, very cheap, worked great. Just because something costs less does not make it inferior. We tried both and SAC305 creates way too much dross in a selective solder machine to make it practicle to use.
