cistec Posted March 9, 2009 Share Posted March 9, 2009 Can any body tell me why I am getting some sort of dark resin at the same time as I am soldering my Les Paul pots in a rewire job? I am using 60/40 mix with 40watt, I clean the tip and tin it before hand. I try to make a solder onto the pot and as I am doing it it starts to produce this dark substance like resin under the solder and on the pot and I am sure this is causing the problem I am having in grounding and making a good contact...Or i could be wrong and this is a normal reaction when soldering.. Can any guru explain why this is happing or tell me what to do to stop it please. cistec Link to comment Share on other sites More sharing options...
Bluemoon Posted March 9, 2009 Share Posted March 9, 2009 It is probably just the flux in the solder. Did you remove all the old solder first before resoldering? You also don't want to put the iron on the contacts for too long. The best approach is to put the iron against the two contacts for a second or so and then add the solder. You don't want to put the solder on the iron first and then kind of drip it on the contacts. You won't get a good connection that way. You also run the risk of dripping the solder on other components. Here is a really good video that might help you Link to comment Share on other sites More sharing options...
Slogold Posted March 9, 2009 Share Posted March 9, 2009 Some pots are coated w/ wax of some sort. So when you solder, this wax coating melts and burn leaving black residue. Link to comment Share on other sites More sharing options...
