[sdiy] broken through hole

[Peter Grenader]

You pulled the plating out of the hole or just the pulled the pad off?

High heat soldering irons have their benefits and deficits.  They HATE small
PCB pads (maybe actually its the other way around).

The hole is toast.  buzz out where each trace went and as Troy suggested
break out the blue wire and run it to all places it would have gone.  Try
not to solder directly to the pics or IC...there usually is a thru hole
somewhere you can tack something to.

A short blip about putting the component legs through the now un-plated
hole:  This is a grand idea, unless there a trace running on both the solder
and componet side of the destroyed hole.  It in fact there are signsls
coming from both sides,  because the lead of the component is now trimmed
pert near the body, you probably don't have enough room on the topside to
lift it off the surface to make sure the componet side pad is soldered to
the lead -and- long enough to attach the bottom side trace to the tail of
the same lead.  I would not see this as reliable in the long term.

It's back to blue wire.  if anyone is doubting its reliability, try to see
the photo of the Buchla 700 board on the AH list.

I totally fried a pad on an Analog Systems Gate Delay I have.  Blue wire did
the trick.  just had the effected leg of the tranny sticking out like a kick
stand and popped the other end against the trace it woulda been shorted to
once I removed the soldermask.
