The idea behind this instructable is to outline a different way of transferring toner to the board aside from the methods we have available to us currently. Instead of transferring the toner using an iron transfer method, you use an electrostatic deposition mechanism (powder coating gun) to deposit the toner on the copper clad board, and then selectively melt the toner using a laser cutter (that has an engraving option as well).
1 powder coating gun
1 air compressor
1 air regulator
1 compressed air moisture trap
1 laser cutter w/engraving capability (Luckily, I have access to the one at the Arch Reactor, a hackerspace in St. Louis, MO)
1 paint booth
1 copper clad board
1 bottle of refill toner (I used Brother brand, but I suppose any type will do, the laser isn’t too
Hydrochloric Acid (Muriatic Acid)
Plastic watertight container
A respirator or dust mask (>N95 perferred)
And a design/circuit you wish to put onto the copper clad.
Once you have all these things, we can get started.
DISCLAIMER: If you follow this instructable, please take your safety into consideration. Note that I have set up environmental engineering controls that are adequate for my own use (paint booth) and that you are responsible for your own safety in your shop/workplace. If you do not have an environmental set up like mine, please consider getting a respirator! It is a good thing to have in your tool kit for all kinds of safety reasons!
