What are the advantages of PCB multilayer boards

If we compare a PCB single-sided board with a PCB multi-layer board, without discussing its internal quality, we can see the difference through the surface. These differences are very important for the durability and functionality of the PCB throughout its service life. The main advantages of PCB multi-layer boards: This circuit board is resistant to oxidation. Diverse structures, high density, and surface coating technology ensure the quality and safety of the circuit board and can be used safely. The following are the important features of high-reliability multi-layer boards, that is, the advantages of PCB multi-layer boards:

1. The normal copper thickness of the hole wall of the PCB multi-layer board is 25 microns;

Advantages: Enhanced reliability, including improved z-axis expansion resistance.

2. No solder repair or open circuit repair

Advantages: Perfect circuits ensure reliability and safety, no maintenance, and no risk.

3. Exceeding the cleanliness requirements of IPC specifications

Advantages: Improving the cleanliness of PCB multi-layer boards can improve reliability.

4. Strictly control the service life of each surface treatment

Advantages: Soldering, reliability and reduced risk of moisture intrusion.

Whether in the manufacturing assembly process or in actual use, PCB multi-layer boards must have reliable performance. Of course, this is related to the equipment and process technology level of the PCB board factory.
