Quoted from Pecos:
I clean off all dust with a small paintbrush. I use flux, 'Master Mechanic Solder Paste, cleans * fluxes.' Here is a pic of my soldering/desoldering station:
I have always been able to solder on only the solder side but learned soon enough that this didn't work with the bridge rectifiers. So, yes, I soldered both sides.
The blackened area is where the trace was, the important word being 'was.' When I cleaned the area with Isopropyl alcohol, part of the trace broke off. I used two pieces of speaker wire and solder to replace the trace.
I can normally do a decent job soldering components on these boards, but these bridge rectifiers have been nothing but trouble.
I'm running my adjustable temperature solenoid station at 310º. I was running at 360º but the Chinese Yihua soldering station was going through too many heating elements. 310º seems to work fine for me.
I have a Hakko desoldering gun. Yes, I remove all old solder. It's fun sucking up that old stuff with the Hakko! Thanks mom, dad and brother for the gift!! It's been a real time and board saver!
Thanks ralph67 for taking the time to list out the helpful soldering tips. I will admit that I don't keep my soldering tip clean. I will change this bad habit immediately.
Use a choir-girl copper scrubber in a tuna can for easy cleaning of tips.
You can buy something like this also.
