[... about prototyping SMT ...]
At work I have a collection of 0.03" thick PCB patterns. They are layed
out on an uncut PCB sheet. I also have a set of tin-snips.
One of the patterns is a SO-200 package. On each side of it are two rows
of slightly larger pads at twice the spacing. Each pin of the SO-200
pattern is connected by a trace to one of these pads. By snipping lets
say about 10 pins worth of the SO-200 pattern out of the board and super
gluing it to a sheet of copper clad, I can make a place to mount an SO-8
With the SO-8 part soldered in place, I then select other bits of the
sheet to glue beside the pattern to make places for the 1206 resistors
Once the parts are held in place, I then cut and strip wires to run
between them. These are soldered to the pads beside the SO-8 and the pads
hooked to the 1206 parts. With careful placement of the wires the results
match a finished PCB fairly well.
