Hi All,
Maybe we should also talk about how we go from circuit to
circuit boards. What do you think fellow Perf-board-ers?

John

That would be so nice WOULD YOU PLEASE .

Hi listies,

Perf-board? I'd rather wire-wrap!

Hi Alan.
Some of the banking stuff I worked on was wirewrap. Many
mods, three to four levels on extra long IC pins. After years of
wirewraping I went back to Perfboard with bare wire.
I use .1 spacing Perf board. I use it to design all my boards to
this day. The .1 grid can be brought up in TurboCad. The Perfboard
Prototype quickly becomes a PCBoard.

Hi John,

Actually I DO use pref board. I use it to try out new wire-wrap board
layouts. Press the wire-wrap sockets into the board anywhere, then when
the sockets and other components all fit, it's quite simple to draw it
into whatever CAD you need. This guarentees that the parts needed will
fit. However, I'm always trying to cram N+1 parts onto a board!

I just joined this group, as I have had the need lately to make quick
concept proto PCB's for clients, where there simply wasn't time to send them
out to a fab house to have made.

At first I tried perfboard, the kind with copper strips one way, ala
veroboard - that works, but if the circuit is not quite cast in stone and
needs fiddling with, you quickly end up with an intolerable christmas tree
mess.

I had some pres n peel blue sheets lying around, but for some reason my
laser printer decided to chew them up - didn't bother it a few years ago
when I first used the stuff. The actual PCB layout took maybe 2 hours.

In desperation, I printed the layouts on plain laser printer paper, ironed
that onto copperclad board and washed off the paper - not perfect, but quick
and in the same time it would take me to build up a circuit on perfboard, I
had workable etched boards. I'll never use perfboard ever again, unless it's
for a simple, known circuit.

My 2 cents.........

If I have to do this kind of sudden death construction much more often, I
will probably build a small milling/drilling machine, it will be worth the
trouble. In the distant past I bought on of those Neuractor kits, the frame
is a total and absolute waste of time, so I gave up on it. The motors,
leadscrews and bearings should be usable, so I just have to come up with a
simple to construct frame - one day..........

Hi Lukus,
I use solderless breadboards then Perfboard and then PCBoard.
It's an old habit that has served me well. Years ago I worked with an
engineer who used self sticking traces. At the time I was etching my
own boards. Looking back the idea was not that bad. I worked on
repairing aircraft cockpit instruments. After that I got the bug for
perfection. Now I am more flexible. The self sticking pads and traces
along with perf board were perfect for some people. Has anyone seen
them lately.
