One problem occurs if you use leaded solder on surface-mounted

Huh? What the devil are you talking about?

This is not new. Tektronix used to include a bit of silver bearing
solder with their scopes so you wouldn't ruin the plated ceramic
terminal strips if you changed out parts.

So adding tin/lead solder to a silver component terminal turns the
connection into what, a non-conductive roofing shingle or something? I'm
pretty sure I would have heard from a customer or two if the thousands
of RoHS components I've soldered with 63/37 weren't conducting
electricity.
