Homebrew PCBs

Hi Martin,

This is what I do. I've never had any formal training, so my technique
might not be the best, in which case, I'm sure that one of the more
knowledgeable members will correct me :)

I use liquid flux. I paint the pads with it. It's slightly tacky. If
that's not enough, then I use a pair of tweezers to apply pressure from
the top and use a very small amount of solder on the tip of the iron.
This is typically good enough for tacking purposes. You're supposed to
heat the part and apply the solder to the part, rather than putting the
solder on the tip, but with one hand holding the tweezers and one hald
holding the soldering iron, there's no hands to hold the solder.

Once the part is tacked down and everything lines up properly, I
properly solder the remaining pins, and then come back and redo the
original tack.

You can get liquid flux in a pen from Digikey. I also got a bottle from
my local electronics supplier.
