Re: [TenTec] Soldering oxidized circuit cards

[Stuart Rohre <rohre@arlut.utexas.edu>]

A Scotchguard (tm) pad is a good way to polish a dirty board.
If the board has coatings over the areas NOT to be soldered, then you 
may have to cut a pad up into smaller pieces to polish small areas of 
copper.

Before polishing, you might clean a kit board with alcohol on a Q tip, 
to see if it is just a mild surface oxidation.  It is unusual for a new 
kit board to oxidize before the builder gets it.  How old was the kit 
where this happened?
