What is the PCB? PCB printed circuit board, also known as printed circuit boards, the provider of the electrical connection in the electronic components. It has a history of more than 100 years of development; It is the design of the main landscape design; The principal advantage of the circuit board is greatly reduce wiring and fitting error, improves the automation level and rate of productive labor. Below is the experts to answer what is the PCB:
Printed circuit board, also known as printed circuit boards, printed circuit board, or PCB, English abbreviation PCB (printed circuit board) or the PWB (printed wiring board), insulation board as base material, cut into a certain size, with at least one conductive graphics, and cloth have a hole (such as component hole, fastening hole, hole metallization, etc.), is used to replace previous device electronic components of the chassis, and realize the connection between the electronic components. Because of this plate is made of electronic printing, so called \"printed circuit board. Used to call \"printed circuit board\" \"printed circuit\" is not exact, because on the PCB and not only wiring of components of printing.
Because of the printed circuit board is not generally end products, so in the name of the definition, slightly chaotic, for example: personal computer motherboards, known as the mainboard, and cannot be directly referred to as circuit board, although there is the existence of the circuit board in the motherboard, but is not the same, so the evaluation industry both on but can't say the same. Such as: because of the integrated circuit parts load on the circuit board, so the news media called him the IC board, but actually he is not the same as the printed circuit board. We usually say that the printed circuit board is refers to the bare plate - no components on the circuit board.
Before appears in the printed circuit board, electronic components of interconnection between relied on wires connected directly and form a complete circuit. Bread now, circuit board was just as effective experimental tool, and printed circuit board in the electronics industry has become the dominant position.
