I am slowing getting my feet wet in this technology.
The ignition computer is part through hole and part
surface mount as my PCB supplier had a limit on
the number of holes,

I bought some solder paste from chip quick and it came
in a 1/2 inch plastic hypodermic needle. The plastic expanded
and contracted when you did not want it to :)

The gift that kept on giving :) Poor control over the
size of the solder paste dot.

So I made an aluminium version and went down on the
cylinder size for more control.

The $20 griddle can solder about 2 dozen of my surface mount boards in
5 or ten minutes. It reaches 400 F which is about 220 C.
