5.Basic knowledge of PCB
PCB circuit board, also known as Printed circuit board, is the provider of electrical connections to electronic components.It has a history of more than 100 years;Its design is mainly layout design;The main advantage of circuit board is to reduce the error of wiring and assembly greatly, and improve the automation level and production rate.
The number of circuit boards can be divided into single panel, double panel, four-layer board, six-layer board and other multi-layer circuit board.
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.For example, because an integrated circuit component is loaded onto a circuit board, the news media calls him an IC board, but in essence he is not the same as a printed circuit board.The printed circuit board we usually refer to is the bare board - the circuit board without the upper component
