From: Jamie on 1 May 2010 18:36 As the subject states. I have several panels that have the connections soldered on how ever, one of them broke off and I had one hell of a time soldering the wire back on. Surface appears to be nickel or some very hard to solder metal.. There is a thin transparent layer of a tan coating that frees very easily when hit with heat. I don't know if that is some sort of catalyst for soldering or a protective spray.. Its possible because I can see it soldered else where. At least it looks like solder.. Any ideas? Jamie.

And I think the tan layer it what's left when the conductive print comes off ;( Cheers

Guess I'll give that a try next time, Thanks. Thanks. |
