High quality PCB circuit board

Any product quality is the key to success, and the circuit board is no exception. High quality PCB boards need to meet the following requirements

1. After the components are installed, the telephone should be easy to use, that is, the electrical connection should meet the requirements;

2. The line width, line thickness and line spacing of the line meet the requirements, so as to avoid heating, breaking, and short circuit of the line;

3. It is not easy to fall off due to high temperature copper skin;

4, the copper surface is not easy to oxidize, affecting the installation speed, it will be broken soon after oxidation;

5. There is no additional electromagnetic radiation;

6. The shape is not deformed, so as to avoid deformation of the outer casing after installation and the screw holes are misaligned. Now it is mechanized installation, the hole position of the circuit board and the deformation error of the line and design should be within the allowable range;

7, and high temperature, high humidity and special environment should also be considered;

8. The mechanical properties of the surface must meet the installation requirements;

9, circuit board technology; exposure process circuit board, silk screen process circuit board,

10, there are surface; OSP engage in oxidation, rosin, spray tin, sink gold.
