Homebrew PCBs

Hi,

You're mixing 2 techniques; photo-sensitive and toner transfer.

The transparencies are used to project an image of a circuit onto a special
photo-sensitive PCB using fluorescent light.

Toner transfer uses special paper, much like what they use to transfer
iron-on decals onto t-shirts.

Check up on the group links or search Google for "pcb toner transfer
method".
