Printed circuit board, also known as printed circuit boards, electronic components, electrical connection provider. Its development over 100 years of history; it is primarily designed layout; the main advantages of circuit board layout and assembly are greatly reduced errors, improved level of automation and production labor rates.
Printed circuit board, also known as printed circuit boards, printed circuit boards, referred to as the PCB manufacture, the English referred to as PCB (printed circuit board) or PWB (printed wiring board), the insulation board to the substrate, cut to size, on which with at least one conductive pattern, and cloth with a hole (such as component holes, fastener holes, holes, etc.), electronic components used in place of the previous device's chassis, and to achieve the interconnection between electronic components. Since this board is made by electronic printing, it is known as the "printed" circuit board. Used to call "PCB" for "printed circuit" is imprecise, because the PCB is not "printed element" and the only wiring. pcb assembly is base on pcbs.
It is important electronic components, electronic components of the support body.
Since the printed circuit board is not a general end product, so a little confusion on the definition of names, such as: personal computer motherboard, called the board, not directly referred to the circuit board, although the motherboard in the presence of a circuit board, but not the same, so when the assessment industry, the same can not be said about both. Another example: because of the integrated circuit components mounted on circuit boards, which the news media called him the IC board, but in fact he is not the same as the printed circuit board and pcb assembly board.
