I have a requirement to prototype more circuits.
Last few decades I've relied on Proto-Boards,
prior to that (when IC's weren't common) I used
"peg-board" with bolts through the holes and
nutted and wing-nutted the circuit components.
That was nice cuz of ease of measurement as
every bolt was a Test Point.
I'm thinking now of using Proto-Boards as IC
sockets and taking the wiring from them to
peg-board which is ~ 1"x1" holes.
((I'm finding Proto-Board to cramped)).
BTW, most of my stuff is less than UHF.
Can anyone recommend a better system?
If you can get all or at least nearly all parts in thru-hole you can use
vector board with a ground plane. If it has to be mostly SMT I'd do a
quick-spin layout and have it made at one of the PCB "fast food" places.

Jeorg would you mind linking me to what you
mean by the vector board process you described.


It looks like this:

With some luck you can find smaller and less expensive versions. I mostly use "Eurocard" size which is 100mm by 160mm. Basically there is a ground plane on one side with enough clearance around the holes so it doesn't short IC pins and the like to that plane. The really good ones also have plate-through holes. When you want to connect something to ground you can do it right at the pin of the part.


When I prototype I begin with a theory, (schematic)
then refine it or discard it, and start anew, so I need
to make swift revisions.


If you expect a lot of changes spread the parts a bit because each hole can only take so many dismantling cycles.
