I've been using the same soldering gun and solder from Walmart. I had no problem in the past soldering wires, not the greatest, to the pads of a esc, motor and so on. This time I have a 4in1 esc that for some reason I can't get the solder to stick on this esc. I was wondering if there some sort of coating on the pads. Can I clean the pads with something like rubbing alcohol. I can't finish up my 4" twig if nothing wants to stick. Any ideas will be appreciated.
