Hello,
I'm trying to figure out if there's any benefit (or drawback) in using Sn60Pb38Cu2 solder vs. regular Sn60Pb40 solder. I have assumed in the past that the added Cu2 helps conductivity, but recently I've heard claims that 1) it can decrease the lifespan of soldering iron tips, and 2) that it only helps when soldering copper wires, by not disolving as much copper when soldering as regular solder would (which also sounds good for soldering copper PCB traces).
Is the Cu2 solder better for general purpose soldering? Worse? The same? The joints do look quite ordinary (no different than the 60/40 ones).
Thanks for reading!
