Re: [TCML] PC boards
Something like a simple driver board is fine for etching. It's certainly
the lowest cost solution for a 1 off board. For drivers, it's typically
a bus voltage, output from the drivers, and the gate for the driver. One
recommendation I would make is to simply etch out the areas between
traces (don't etch out huge areas for a specific trace width). The areas
between each net is simply an etched-out trace to disconnect each net.
This really reduces the copper that needs to be removed and speeds up
Back when I did etch boards (I use board houses these days), I simply
covered the copper clad with good masking tape (wide tape), pencil in
the traces between nets, used a razor blade to cut along the lines,
removed the tape, and soaked the board in etching solution. Worked great
and is simple to do.

I am just building some simple flyback drivers, and I am sick of the
mess of soldering bare wires directly to dangling diodes and transistor
leads, and I want something more permanent than a chunk of breadboard.
Since it doesn't have to be perfect I don't need an incredibly steady
hand (plus I have a little sister with lots of nail polish experience).
I planned on drilling the holes and inserting the components before I
drew the trails to make sure everything goes where it is supposed to.
Thanks for your help guys.
