The most widely used type of circuit boards in the current market, multilayer circuit boards have firmly occupied the mainstream in the market once they appeared with their unique advantages. For the circuit board, the most important requirement is its own reliability to avoid some hidden safety hazards during use.

Due to the use of new production materials, the volume of the multilayer circuit board is small and the weight is relatively light. Most importantly, the connection lines of the internal components are also greatly reduced. I believe that many people will get a headache when opening a circuit board with the dense connection lines on it, but this situation will not appear on the circuit board with a clear wiring level. By increasing the number of wiring levels of the circuit, not only can it provide designers with more imaginable space in the design, but also make the structure more reasonable. It can also greatly strengthen the rationality of the wiring. The overall formation of a set of reasonable circuit processes is like an elevated highway in transportation. After the hierarchical line layout is carried out, the current can pass through it more quickly and reasonably.

In addition, the reliability of the multilayer circuit board is well received because of the internal magnetic circuit shielding layer. The magnetic circuit shielding layer not only has the basic function of power shielding like the traditional shielding layer, but also has the effect of heat dissipation. This means that even if it is used for a long time, the internal circuit will not cause a fire accident due to the high temperature generated by the current. It further improves the overall safety factor, even if it is used for a long time, there is no need to worry about safety issues.
