RE: [Homebrew_PCBs] Re: Through plating - double sided

2006-04-12 by Alan Marconett

HI Jan,

I DO like the effect.  I really wouldn't want any acid residue left on the
board.  

I see the "tinning" process, but as it involves heat as you describe it,
then one must go over EACH trace in it's entirety to tin?

I'd really not want to subject the board to any unnecessary trace heading if
it could be avoided.

I was under the impression that some sort of plating of the tin could be
done; either by current or a chemical solution.  With current, it would seem
that a connection would have to be made to EACH trace, which might prove
difficult.

On through-hole pads, I've heard (but never used) that small eyelets can be
manually inserted in the holes, and then peaned over.  That would be a job!
