Circuit board Introduction

- Aug 11, 2017-

Circuit board Name: PCB, PCB board, aluminum substrate, high-frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit board, ultra-thin PCB, printing (copper etching technology) circuit board. The circuit board makes the circuit miniature and intuitive, which plays an important role in the mass production and optimization of the fixed circuit. Circuit board can be called printed circuit board or printed circuit board, the English name is (printed Circuit Board) PCB.

circuit board mainly by the pad, through hole, installation hole, wire, components, connectors, filling, electrical boundaries, and other components of the main functions are as follows:

Solder PLATE: A metal hole used for welding the pin of a component.

Over hole: There is metal over hole and non-metallic over hole, wherein the metal is used to connect the component pins between each layer. PCB Price

Mounting holes: For fixing the circuit board.

Conductor: The electrical Network copper film used to connect the pins of the components.

Connectors: For the circuit board connection between the components.

Filling: Deposited copper for ground network can effectively reduce impedance.

Electrical boundary: Used to determine the size of the circuit board, all components on the circuit board can not exceed the boundary.
