Blank PCB

Blank copper pcb board is a printed circuit board, also called printed wiring
board, which is an important electronic component, the support of the electron
component, and the supplier of the electrical connection for the electron
component. Since it is made with electron printing, it is called a "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.
Generally, the color of the PCB is green or brown, which is the color of the
solder mask. It is the protective layer of insulation to protect the copper
foil and preventing the parts from being soldered onto the incorrect positions.
Silkscreen will be printed on the solder mask where words and marks (mostly
white) will be printed in order to highlight each position of the parts. The
silkscreen is also called a legend.
