PCB Manufacturers, Printed Circuits Boards Manufactures
There are various methods for the hobbyist to make PCB boards. I use the toner transfer method because it is cheap and requires relatively little setup or equipment. You need access to a laser printer or photocopier, an iron, and you'll need an etching solution.
The electrical circuit is completed by interconnecting the different layers with plated through-holes, placed transverse to the board at appropriate places
