What kind of iron are you working with? What kind of solder are you using? Those 2 things alone can make a big difference. Practice is necessary too, of course–but if you’re trying to work with inferior equipment and/or solder, it may be harder than it should be…
Ooh, i see. Unfortunately i don’t have any experience soldering these…just pcbs, wires, etc. Hopefully someone else here can help out!
