Teach you how to identify the quality of the circuit board

Circuit board manufacturers have strict standards when producing and manufacturing circuit boards. So how does a circuit board factory distinguish the quality of a circuit board? There are mainly the following points.

High-quality PCB circuit boards need to meet the following requirements

1. It is required that the phone be easy to use after the components are installed, that is, the electrical connection must meet the requirements;

2. The line width, thickness, and spacing of the line meet the requirements to prevent the line from heating up, breaking, and shorting;

3.The copper skin is not easy to fall off under high temperature;

4. The copper surface is not easy to oxidize, which affects the installation speed. It will be damaged soon after oxidation.

5.No additional electromagnetic radiation;

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

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

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

The above is the method of judging the quality of the PCB circuit board. When choosing a PCB circuit board, you must keep your eyes open.

9. Circuit board technology: exposure circuit board, silk screen circuit board,

10. There are on the surface; OSP engages in oxidation, rosin, tin spray, and gold.

The above are some points on how to distinguish the quality of circuit boards from circuit board manufacturers.
