I had something a little strange happen while soldering yesterday. There were 2 pins, out of 24 total on an IC, that I just couldn't get - the solder would find its way to, and then stick to, the tip of the soldering iron. The other 22 went fine.
I made sure I was giving it enough heat, and tried adding flux, but neither did the trick.
There's a lot of flux gunk there (and there already was before I added more) so I'm going to pick up some 99% isopropyl alcohol and try cleaning the area with that.
Any suggestions for what else I should try?
