Hello Norm,
yes, you are right, that's the way I do it. You can see that on the two
attached pics. You can also see that I sometimes cut small islands into the
Copper with an Exacto knife to solder down through hole parts and Tantalum caps
for example.
For SMD IC's I solder down the GND pins, then use small caps from the board
to the power pins, and wire the VCC with rework wire.
Excuse the poor picture/board quality, these are the only two boards I had
able to be photographed - I usually use thermal glue to seal the finished
boards.
This is a very quick and dirty, and surprisingly good electrical way to
build something. I've done circuits with over 1GHz like this!
Hope that helps,
bye,
Said

Said,
I subscribe to the timenuts reflector. A few days ago(June 2), you
described a method of dead bug construction using SMT IC's and discrete
components. Do you have any pics of the details? How exactly do you
attach the bypass caps to the power pins?
My assumption is you're using single sided fr4 and the copper is ground,
with vcc wired as needed.
This will be my first try at SMT. I've played a bit with wire wrap and
plugboard.
This will be used for a pulse shaper/divider network.
Thank you for any help!
