What is a PCB What is a circuit board (circuit board)

What is PCB? The PCB board realizes the functions required by the circuit designer. The inventor of the circuit board is the Austrian Paul Eisl (PaulEisl adopted the circuit board in a radio device in 1936 and has occupied an absolute dominant position in the electronics industry. As the name suggests, the content of the printed PCB does not deviate from the process. information.

  What is a circuit board? The various layers in the PCB are tightly integrated. But if you look closely at the motherboard, you might be able to see it. The circuit board system is classified into the following three types:
1. Single-Sided Boards
   We just mentioned it, so we call this kind of PCB a single-sided (Single-sided). Because single-sided boards have many strict restrictions on the design of the circuit (because there is only one side, the wiring can not be crossed * and must be a separate path), so only early circuits use this type of board.
2. Double-Sided Boards
   This kind of circuit board has wiring on both sides. However, to use wires on both sides, there must be a proper circuit connection between the two sides. The “bridge” between such circuits is called a via. A via is a small hole filled or coated with metal on the PCB, which can be connected to the wires on both sides. Because the area of ​​the double-sided board is twice as large as that of the single-sided board, and because the wiring can be interleaved (it can be wound to the other side), it is more suitable for use in circuits that are more complicated than the single-sided board.
3. Multilayer board
  【Multilayer board】In the case of more complex application requirements, the circuit can be arranged in a multilayer structure and pressed together, and through-hole circuits are placed between the layers to connect the circuits of each layer.
