Subject: [TN] Soldering a wire to PTH


I have a question about hand soldering of a wire to solder plugged via.
Nowadays there is a temporary solder mask (TSM) preventing the soldering of
these plated through holes at wave soldering machine. After wave soldering
the TSM is removed and the wire is soldered to hole at assembly. Now I get
this great idea! What if we just leave the TSM out and let the holes to be
filled with solder. At assembly the solder will be melted and wire will be
placed to hole and the solder joint is formed with proper final heating and
cooling.

What problems or risks can be expected, when doing such soldering? Are the
joints as reliable as normally? I won't like to remove the solder before
placing the wire, I would like use it to form the solder joint to save time.
Would I need some extra soldering wire or flux?

Have a nice weekend

B.R.
