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.

Well, it was silver-*bearing*: still mixed with lead, no? (I assume this
is pre-RoHS.)

I'm sure. We keep a bunch of 3% Silver along with tin/lead for the
extra wetting it gets on some stuff.
