Analysis of Yantai PCB Processing: Advantages of High Quality PCBs

Nowadays, it is very common for everyone to have a mobile phone. The continuous emergence of mobile phones and electronic products has not only enriched people's lives but also promoted the development of the times. This is all inseparable from the contribution of circuit boards. With the continuous development of circuit board processing in Yantai, the entire industry has become a mix of good and bad. Some so-called small workshops manufacture low-quality and counterfeit circuit boards, affecting the market order. Therefore, buyers must know how to distinguish good from bad circuit boards. A high-quality circuit board should meet the following conditions:

1. After the components are installed, the equipment (e.g., a telephone) should work well, meaning the electrical connections must meet the requirements.

2. The line width, line thickness, and line spacing of the circuits must meet the requirements to prevent the circuits from overheating, breaking, or short-circuiting.

3. The copper layer should not easily detach when subjected to high temperatures.

4. The copper surface should not oxidize easily, as this affects installation speed; after oxidation, the board may fail shortly after use.

5. It should not generate additional electromagnetic radiation.

6. There should be no deformation in shape to prevent the casing from deforming after installation or misaligned screw holes. Nowadays, installation is mechanized, so the deformation error between the board's hole positions, circuitry, and the design should be within the allowable range.

7. Resistance to high temperature, high humidity, and special environments should also be considered.

8. The surface mechanical properties must meet installation requirements.

The above eight points are our Yantai Zhange Electronics Co., Ltd.'s explanation of the conditions a high-quality circuit board should possess. The editor believes it is very necessary for everyone to learn and understand this, as it can help avoid being cheated when purchasing circuit boards.
