The process of producing circuit boards is backwards and forwards, but as experienced circuit board professionals, there is nothing unusual about it. This is our daily homework Today we are going to talk about friends and customers from other professions or products who often ask why your circuit board is so expensive. Although we don't know why they say that, it is generally due to a lack of understanding of the process of the circuit board and only looking at the price. Here are some differences between good and bad circuit boards:

The demand for high-quality PCB circuit boards meets the following requirements

1. Require the components to be installed and the telephone to be user-friendly in the future, that is, the electrical connection should meet the requirements;

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

3. Copper skin is not easily peeled off under high temperature;

4. Copper surface is not easily oxidized, which affects the speed of the device, and it will soon break down after oxidation;

5. No additional electromagnetic radiation;

6. The appearance is not deformed to avoid deformation of the device's rear shell and misalignment of screw holes. Nowadays, all devices are mechanized, and the hole positions of the circuit board and the deformation errors between the circuit and the plan should be within the allowable range;

7. High temperature, high humidity, and resistance to special environments should also be taken into consideration;

8. The mechanical properties of the surface should meet the requirements of the device;

The above are the methods for judging the quality of PCB circuit boards. When choosing a PCB circuit board, be sure to keep your eyes open.

9. The process of circuit board includes:; Exposure process circuit board, silk screen process circuit board,

10. On the surface, there are; OSP is used for oxidation, rosin, tin spraying, and gold deposition.
