Does PCB mean copper on copper and copper clad in Protel?
This kind of copper (or copper) is not stuck with a copper layer, but in the corrosion of the original copper layer to retain the use of shielding.
In order to prevent mutual interference between the wires caused by induction, one of the methods can be used between the shielding wire, is paving (also called copper), package, the inner partition to solve, it is the way to get the copper layer and the wire segmentation without wiring had been corroded and preserved and ground connection. The formation of the ground shield, can effective anti-jamming.
The PCB board is also called a printed circuit board, not printed on the circuit. Instead, the copper sheet is glued to the insulating substrate to form a printed circuit board. This kind of board is also called ccl. Then in the copper clad plate, corrosion resistant paint or other ink to draw out the connected components of the connection, finished CCL wire into the soaking solution to corrosion of copper, there is no line drawn place will be eroded, draw a line where paint protection, will be preserved, it is printed the circuit board (PCB board).
