Printed circuit boards, also called Printed circuit boards, they are electrical connections for electronic components.
Printed circuit boards are more often referred to as “PCB” than as “PCB board”.
It has been in development for more than 100 years; Its design is mainly layout design; The main advantage of 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 layers of the circuit board, it can be divided into single panel, double panel, four layers, six layers and other layers of the circuit board.
Because printed circuit boards are not common terminal products, there is some confusion in the definition of the name. For example, the mother board was used in personal computers is called the main board and cannot be directly called the circuit board. Although there are circuit boards in the main board, they are not the same. Another example: because there are integrated circuit components loaded on the circuit board, so the news media called it IC board, but in essence it is not the same as printed circuit board. When we talk about printed circuit boards, we usually mean bare-board circuit boards that have no primary components.
