If you have a laser cutter, I've seen awesome results from coating the board with spray paint, burning it off to make an etch mask, and etching that. If you're working with good, rectangular FR-4, I bet the registration is good enough to do double-sided.<div>

Inkjet? The process involves either modifying an existing printer or<br>
making a CD tray holder to fit a small copper-clad board, printing<br>
directly on the board, heating it to cure the ink and etching.<br>

We've done toner transfer PCBs at the space, but we're looking for<br>
something easier and more reliable.<br>
