Etching Your Own Boards

Etching your own boards is not all that hard. Once you have created the circuit and laid it out, its just a matter of printing it in mirror onto some toner transfer paper and then ironing it onto a nice clean and sanded sheet of FR4. Sanding with 400 grit is essential, the toner needs a rough surface to cling onto. From here it is just a matter of putting the board in etching solution and waiting till the exposed copper is gone.
