When soldering, sometimes I will have a small piece of solder that seems to string when using resin core 60/40.
I have cleaned the tip using fine emory board, but these still occur.
Is there a way to prevents these, as it is tricky to repair when using a solder wick as sometimes it will "suck up" more than I need.
You might be using a tip temperature that is too low, or you are using far too much solder on the joint, or you are soldering for too long on a joint, allowing the solder to oxidise.
