|A printed circuit board
(PCB) has all of its wiring 'printed' onto a board. It does away with most
of the hard wiring. The board is made of insulating materials and the wiring
is made of a conductive material known as tracks or traces. Suitable slots
are made to fit processors, oscillators and other small electronic
components. Extremely complex circuits can be printed into a PCB. Printed
circuit boards can prove to be very cost effective in mass production
because the process is fully automated and the number of defects is quite
low. Printed circuit boards are also known as printed wiring boards (PWB)
and etched wiring boards.
Copper plating is done on the insulating board and the required wiring is obtained by removing the unwanted copper. Some PCBs are made by adding traces to the bare substrate usually by a complex method of multiple electroplating. Some PCBs have trace layers inside of the the PCB. These devices are called multi layer PCBs. These units are made by bonding together separately etched thin boards. After the circuit board has been manufactured, components are connected to the traces by soldering them to the board.
PCBs are very dependable and inexpensive and more consistent in high volume production. PCBs are commonly used around the world in electrical and electronic circuits for computers, consumer and white goods, electrical machinery and automobiles, etc.
