=== Double Sided Boards ===
There's a couple of extra steps required for two-sided boards:
* Print both sides out on separate sheets (or cut one sheet in half)
* Align the two sheets and staple them together to retain registration
* Cut them to size so that they are slightly smaller than your photo PCB material.
* Remove the protective film on both sides, place the PCB between the two transparencies leaving a slight overhang, and '''tape the PCB to the transparency. ''' so it does not move when you flip it during exposure!
