I'm getting a bit worried. The left one is easy. The right one cries for tons of flux I guess. As my iron's tip is large compared to the tiny pins I'll have to use "flood and suck" for this one. Or maybe drag soldering works too. I've seen many professional videos using tips that have a little cavity forming a little reservoir for solder. This would help a lot, but I can't find a tip for my iron like that. Only the usual pencil/chisel/cone/45° stuff.
