The wonderful thing about the half-hole function of PCB

PCB half-hole is a special process in the circuit board manufacturing process. It has a wide range of functions, such as: increasing circuit board density, strengthening circuit board rigidity, enhancing intra-board signal transmission, saving space and reducing board thickness, etc. This article will elaborate on the wonders of PCB half-holes from four aspects, including increasing circuit board density, strengthening circuit board rigidity, enhancing signal transmission within the board, saving space, and reducing board thickness.

1. Increase circuit board density

By processing half holes on the circuit board, the density of the circuit board can be made higher. Half vias can be used in dense sections, allowing you to fit more components into the constrained space, which will improve overall board performance and power, significantly reducing board size and power without increasing board area. weight.

2. Strengthen the rigidity of the circuit board

There is a copper blocking ring next to the PCB half hole. Even if the area where the half hole is located is very thin, it has good mechanical strength. This is because the half-hole processing process makes the surrounding copper layer harder, thereby enhancing the rigidity and planarity of the circuit board. In this way, the circuit board is not only stronger during the entire PCB installation process, but also can withstand the impact of various mechanical stresses and equipment vibrations, and its lifespan and reliability will be higher.

3. Enhance intra-board signal transmission

Half-hole technology can effectively improve the high-frequency and signal transmission performance of the circuit board. It prevents interference across the circuit board between signal and power lines. The half-hole will create a good grounding and shielding environment, form a closed loop on the circuit board, and separate it, which can effectively reduce crosstalk and signal distortion, thereby improving the performance of the circuit board in terms of high frequency and signal transmission.

4. Save space and reduce plate thickness

Since PCB half-hole technology can effectively increase the density and rigidity of the circuit board without affecting the board area and electrical performance, it can effectively reduce the thickness of the circuit board and improve signal transmission and high-frequency performance. This technology is even more important as circuit boards and electronic devices become smaller and smaller.

PCB half-hole technology brings many advantages to circuit board manufacturing and design, providing better performance, smaller size and shorter production cycle. Therefore, in the electronics industry, half-holes are widely used in various application fields, such as communications, computers, medical, and aviation.
