Printed circuit board {PCB circuit board}, also known as printed circuit board, is the electronic components of the electrical connection provider. Its development has been 100 years of history; its design is mainly layout design; the main advantage of using the circuit board is to greatly reduce the wiring and assembly errors, improve the level of automation and production labor rate.
According to the number of circuit board can be divided into single-sided, double-sided, four-tier, six-board and other multi-layer circuit boards.
As the printed circuit board is not a general terminal product, so the name of the definition of a little confusion, such as: personal computer motherboard, called the motherboard, and can not be directly called the circuit board, although the motherboard board there is a circuit board, but Is not the same, so the assessment of the industry when the two can not say the same. For example: because there are integrated circuit parts loaded on the circuit board, so the news media called him IC board, but in essence he is not equivalent to the printed circuit board. We usually say that the printed circuit board refers to the bare board - that is, no components on the circuit board.
