A PCB is a Printed Circuit Board. Basically a substrate - usually glass reinforced plastic - with a thin layer of copper over it. You then remove the copper that you don't want left, either by etching it with a corrosive liquid or by routing it off the face of the board.

 

The image there shows what copper should remain on the board. The black is copper, the white is bare board.
