Electro-Graf

Step 5 Tape contact pads

If you intend to add a topcoat to the electro-graf, like in the case of the prototype indoor electro-graf, you need to put masking tape on the circuit stencil to create contact pads. These are where the LED leads or the wires will make contact with spray-on conductive traces and close the circuit. I used 1/2" by 1/4" pieces of masking tape to make the contact pads. Remember to put these on before you spray your topcoat!

The outdoor electro-graf did not require a topcoat of paint or tape to cover the contact pads.
