Subject: Re: [Homebrew_PCBs] Controlled solder paste dispensing

From: Erik Knise <elknise@...>

I solder the majority of my boards by hand. Giving the joint a good
fluxing and then zip soldering does the trick.

I have used one of those air powered dispensers before. They are good
for some applications but not for fine pitch.

I have also tinned the pads, sat the chip ontop and hit it with a hot
air rework tool. This usually works but can still lead to lots of
bridging. That's why if it's only a few parts I stick with hand
soldering.
