Hey guys,
Been awhile... hehe.
I need to make a double sided board. I'm using the MG Chemicals presensitized (or whatever) double sided board, and I don't quite know how to expose it. I've done a few single sided boards. Do I just expose one side, flip it over and expose the other?

It's tricky, but it can be done.
You should mark and drill a few holes, to act as references to align the top to the bottom. Also remember that since you can't really make plated-through holes like the pros do, you have to use solder a short piece of wire through any vias, and of course, solder all through-hole components to both sides of the board (where there is a solder pad on both sides).
You might consider some of the PCB shops, some of which will proto a board for around $20. Do a search in the forum.
