Thanks, I do try all of these, add solder, add flux, use 400C on the iron etc etc not much luck. Well i cleared about 2/3 of them using various combination of these, but some are just... tough!Try adding some fresh solder and a bit of flux when heating it up for removal. Braid may also prove helpful.
I have an 858D clone hot air gun that I use in conjunction with the iron when I have to deal with a ground plane soaking heat up. If the iron isn’t enough, usually adding the hot air will provide enough heat to clear things out. In my experience, copper wick will just soak up even more heat, which is a problem if the ground plane is posing an issue on its own.Thanks, I do try all of these, add solder, add flux, use 400C on the iron etc etc not much luck.

Ah good tip, in fact, excellent idea! I also have hot air so I'll try that next. I've been sulking for a day or so because of that problem so it gives me "options"I have an 858D clone hot air gun that I use in conjunction with the iron when I have to deal with a ground plane soaking heat up.

Interesting! Just bought a set to try.Old thread, but I figured I would chip in with some info. I've just gotten a set of "desoldering needles" from AliExpress. They're basically stainless steel needles that you put into the heated-up joint and solder won't stick to them. They clear holes fairly well, although I've only needed to use the smallest one and the plastic handle is getting a little melty from heat over time.

Lots of vendors for these, so please shop around.
Aliexpress doesn't take paypal so I ordered a set from ebay to test.Interesting! Just bought a set to try.
