Multilayer Board: Its 5 Critical Advantages are becoming more and more clear with the development of modern technology. More and more advantages of Multilayer Board are now displayed and used. However, in PCB industry, there are usually 5 popular and critical advantages that are frequently mentioned by the scientists. They are:

1. Technological Revolution Of Multilayer Board

Via micro-blind hole/ buried hole technology, precision layout of line width/space 20/20μm can be reached on Multilayer Board. This will reduce the area of smartphone motherboard by 40%, while increase signal transmission speed by 30%. And this characteristic will also directly promote the integration of 5G base station RF modules on a single board.

2. The Spatial Reconstruction Capability of Multilayer Board

High-end Multilayer Board usually adopt 8-32 layer stack technology, this will let 1200 solder joints contained into per square centimeter. So that the PCB manufacturer can improve the thermal management efficiency by 50%. The 5G board for communication from Shennan Circuits shows that 16 layers design can reduce the total weight by 28%.

3. Breakthrough In The Morphology of Flexible Substrates

PI makes dynamic bending radius 0.1mm for FPC possible. Because od this, the folding screen phone hinge durability reaches to more than 200,000 test. For example, a home-made smart phone use FPC to replace flat cable, and improve the inner space usage by 35%.

4. The Reliability In Extreme Environmental

Multilayer Board can withstand 96H Salt Spray Test, and still can work smoothly in temperature range -40℃~150℃for automotive electronics field. Medical class Flex PCB also have 300℃ instantaneous high temperature characteristics, and can meet requirements of sterilization.

5. Empowering Intelligent Manufacturing

Fully automatic roll to roll continuous production line makes the FPC yield rate reaches to 98.6%. The intelligent production line of Jiepei makes 72h lead time possible. SCC use AI to improve the defect recognition accuracy to 99.2%.

The above 5 advantages of PCB are also critical factors for most PCB manufacturers in China. Such as Sugar and Sayfu in Guangdong and many other PCB factories in the rest places in China.
