Function:

1. Provide all kinds of electronic components (IC, Ω, C) fixed assembly of the mechanical support.

2. Implementation of the electrical connection between electronic components or electric insulation, provide the required electrical properties, such as characteristic impedance, high frequency microwave signal transmission.

3. provide resistance welding welding graphics for components.

 

Importance:

· 1.PCB is Modern electronic information industry important components, the source of electronic products

2. the base of Electronic information industry. Where there are electronic products, where we will certainly be PCB.

3. without computer and software, electronic equipment = ordinary box. No semiconductor and circuit board, electronic components = ordinary stones.
