Yesterday I soldered quite some things, but I'm still a beginner.
I noticed that sometimes it happened that sometimes I use to much solder. When trying to remove it, I heat the pin with solder so it melts, and when pulling back to clean the tip to remove the excessive solder, I notice that the remaining solder on the pin just after I remove the solder tip 'grows' and leaves some kind of circle/ball-form, as if there is some air inside it. I don't think this is very good (also the result looks like a ball.
I think this is because the flux is gone after the first try.
I tried solder wick but don't get very good results with it. Would adding flux with a flux pin help? (I ordered it, but haven't received it yet).
Of course the 'real' solution is to not use too much solder (I use already 0.5). But maybe there are better tips how to 'fix' pins with too much solder.
