A printed circuit board is vital to any mechanically and electronically driven devices. It is utilized to support and connect electronic components through electrically charged pathways from copper sheets laminated to the non conductive substrates. It is massively populated with electrical elements or discrete devices that could be collectively called as printed circuit assembly. Manufacturing of PCB boards necessitates a systematic method by which only the technically trained individuals are allowed to work with.
The design of a printed circuit board is done not only based on the resourcefulness and creativity of its fabricator. Assembly, design and quality control requirements are established by the Association Connecting Electronics Industries, a trade association aiming to set standardized production and assembly of any electronic devices. That is why PCBs have to be designed initially before they are out in the market.
First introduced in the early 20th century, the modern printed circuit boards were created by a German inventor named Albert Hanson which was also developed by an American businessman and inventor, Thomas Edison. In 1904, Edison experimented chemical methods in plating conductors using linen paper. And it was in 1913 that a certain electronics company patented a print-and-etch technique.
Later on, an engineer named Paul Eister enhanced a functionality of the printed circuit for the radio set. This technology spread significantly across the U. S. By 1943 as a basic component for the proximity fuse, an explosive device used in the World War II. This automatically blew up as it drew nearer to its target.
Long before the prototypes of printed circuits were released, point-to-point construction was used. This is a non-automated system of electronic circuit construction. Some time between 1936-1947, another company developed the device and have it sprayed on a plastic board.
Prior before all those enhancements, the electronic components had certain wire leads passing through holes which were then soldered unto a PCB trace. Such construction method is popularly known as through-hole construction, an electronic approach that typically involves the use of lead on the components inserted into the board's holes and a mounting scheme. This is done manually.
Around 1980s, a surface mount system was introduced where electronic circuits were mounted directly on the surface of the board. This technology had then prompted the production of small boards which replaced through-hole construction eventually. But both technologies could be employed on the same board.
Manufacturers at present largely use copper clad laminates, laminates, copper foil and resin Pre-preg. Laminates are created through the use of thermosetting plastic resin that produces uniform thickness of integral final pieces. Common length is between four and eight feet. Standard cloth weaves, cloth thickness and resin percentage are necessary in achieving desired dielectric characteristics. The fabric or cloth utilized in the process determines the resin ratio in a laminate being produced.
Manufacturing of PCB boards also passes through subtractive processes. These involve silk screenings printing, photoengraving and PCB milling. Circuit properties also require chemical etching, a subtractive manufacturing process that is now increasingly important in the production of the board.
