A printed circuit board is a fundamental part of electronic devices, and it helps in assembly of intricate parts within a small space. Though a little expensive in the initial design phase, in the long run printed circuit board has reasonable manufacturing cost and are very sturdy. They last for a long time. In the beginning, printed circuit boards were used in radios during World War II. Later it graduated to the commercial level and has evolved since then.
History
As per the U.S. Patent, in July 31, 1956, M. Abramson got the patent rights for a printed circuit board although it was an Austrian Who first made the printed circuit board in England. The printed circuit board came into existence due to the efforts of an Austrian engineer named Paul Eisler , which was used as part of a radio set. By 1943 this impressive innovation was being used by the U.S to make rugged radios that were used in World War II. Post World War II, the US started using this technology for commercial use. However, it was quite a while before the printed circuit board was more commonly used in commercial electronic goods.
From the second half of the 19th century, the connecting parts like components and wiring of an electrical device was done on a wooden board. It was only in the 20th century that printed circuit boards were developed that had the circuit etched on the surface of the board.
Advantage of a printed circuit board
A printed circuit board reduces the manufacturing cost, offers a very efficient and compact way of wiring, and placement of more components in a limited space.
The future
The need of the modern technology is compactness and miniaturization that leads of the decrease in the size of the components and increasing the number of patterns on a printed circuit board. Hence, in the long run another approach may be required to meet this requirement as there is a limit on how close the printed wires can exist.
