printed circuit

Physics

An electronic circuit consisting of a conducting material deposited (printed) onto the surface of an insulating sheet. These devices are now common in all types of electronic equipment, facilitating batch production and eliminating the unreliability of the hand-soldered joint.

Computer

A physical realization of an electronic circuit design in which the connections between the terminals of individual components are formed from copper conductors supported by a sheet of an insulating material such as fibreglass. The conductor pattern is normally printed and etched onto the sheet and components are then attached to the copper ‘lands’ by hand or dip soldering. The supporting sheet plus circuit is known as a printed circuit board (PCB).
Double-sided and multilayer PCBs are commonly produced. These consist of insulating sheets (normally known as PCB laminate) with a circuit on each side, with interconnections possible between the two layers.

Electronics and Electrical Engineering

An electronic circuit, or part of a circuit, in which the conducting interconnection pattern is formed on a board. A thin board of insulating material is coated with a conducting film, usually copper. Photolithography is then used to coat part of the film with protective material. The unprotected metal is removed by etching, leaving the desired pattern of interconnections. Discrete components or packaged integrated circuits may then be added to complete the circuit.
Double-sided printed circuits are commonly produced in which both sides of the board have a circuit formed on them, with feedthroughs to connect the two sides as required. Printed circuits have been produced with several alternating layers of metal film and thin insulating film mounted on a single board. Boards with up to 12 layers of interconnections can be produced, commonly for digital systems.
The use of plug-in printed circuits in electric or electronic equipment facilitates maintenance and repair. Printed circuits are reasonably robust when subjected to careful handling.
