blank printed circuit board As the electronic instruments become more and more complicated, the parts they need become much more accordingly, and the circuit and the parts on the board become denser. The blank PCB (without parts on) is often called the "Printed Wiring Board (PWB)". The substrate of the board is made of materials with attribution of insulation, thermal insulation, and inflexibility. The tiny wires can be seen on the surface is the copper foil which had been covered the whole board, but partially etched, then the remaining part formed the tiny netted wires. And these wires are called conductor pattern or electric wiring, which is used for offering the electrical connection for parts on PCB.
