[sdiy] Defluxing/Circuit Trace Repair

[patchell]

    If it ain't broke...don't f**K with it!  Modern Rosin Flux does not
"have" to be cleaned off the board.  In critical applications, where you
need high impeadence, cleaning may be nessesary, but, a poorly cleaned
board is worse than a board that wasn't cleaned.

    Please note that some fluxes must be cleaned...If you ever use Kester
331, cleaning is mandatory.

    As far as fixing broken traces...I just scrape off the solder mask and
use #30 wire wrap wire.  Any other appropriate solid wire would work as
well.  I have repaired 7 mil traces in this way with great success.
