I've read the archives as to why solder pits (medium silver
solder) but now that I've already done the bezels (they are pitted
at junction to the bezel plate), how can I fix them (there are
several...argh!) I am using Rio's MY-T-Flux for its firecoat
My-T-flux is not really designed to be a protective coating flux.
The benefit of a self pickling flux is to keep the metal clean
inside joints while soldering, especially if the solder job is
taking longer than planed. Also the joint will clean up easier after
soldering incase you don’t get the solder to flow the first time and
have to go back (yuck).
As for the pitting it could be a lot of things such as over heating
the solder, pickling to long, quenching in pickle to soon after
solidification, re-flowing the solder joint while soldering
something else on the piece. Strong pickle is hard on solder joints
so be careful about leaving pieces in to long. Also, if you can see
the pits in your solder seam try using less solder, a good joint
requires very little solder.
Hope this helps,
