Basic Knowledge of PCB

PCB circuit board, also known as printed circuit board, is the provider of electrical connection of electronic components. Its development has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is to greatly reduce wiring and assembly errors, improve the level of automation and productivity.

According to the number of PCB layers, it can be divided into single panel, double panel, four-layer board, six-layer board and other multi-layer PCB.

Printed circuit boards (PCBs) are not general end products, so the definition of their names is somewhat confusing. For example, the motherboard for personal computers is called motherboard, but it can not be called PCB directly. Although there are PCBs in the motherboard, they are not the same, so the two can not be said to be the same when evaluating the industry. For example, because the integrated circuit parts are loaded on the circuit board, the news media call him IC board, but in essence, he is not the same as printed circuit board. We usually refer to printed circuit boards as bare boards - circuit boards without components.
