HDI board (High Density Interconnector), that is a circuit board with a relatively high line distribution density using micro-blind and buried via technology. The HDI board has inner layer lines and outer layer lines, and then uses drilling, in-hole metallization and other processes to realize the internal connection of each layer of lines.

The electrical performance and signal accuracy of HDI boards are higher than traditional PCBs. In addition, HDI board has better improvement for radio frequency interference, electromagnetic wave interference, electrostatic discharge, heat conduction, etc. High Density Integration (HDI) technology enables more miniaturization of end product designs while meeting higher standards for electronic performance and efficiency.

Advantages of HDI boards

4.HDI technology has better electrical performance and signal validity;

5.HDI technology has better reliability;

6.HDI technology is better in heat dissipation;

7.HDI technology can improve RFI (Radio Frequency Interference)/EMI (Electromagnetic Interference)/ESD (Electrostatic Discharge);

8.HDI technology improves design efficiency;

HDI Printed Circuit Boards, which are known as High-Density Interconnect, are PCBs that use a larger number of interconnections than standard printed circuit boards. Such circuit boards have a pin density of around 120 – 160 pins per square inch, according to most electronics designers and developers. HDI printed circuit boards have dense component placement and denser circuit interconnections, which enable the reduction in the package size or footprint of electronic assemblies built from them. This technology has enabled size reductions for high-performance electronics in consumer products such as mobile phones, tablet computers, laptop computers, digital cameras, as well as enhancements in products for other markets such as medical technology.

HDI (high-density interconnect) printed circuit boards allow for more electronics to be packed into a smaller space, making products smaller in size. These circuit boards have many applications, some of which include:

- Healthcare and medical industry: HDI PCBs are used in implanted devices, like cardiac pacemakers, and external devices such as hearing aids.

- Automotive industry: Smaller and lighter electronics enabled by HDI technology save space and reduce the weight of vehicles.

- Consumer devices: HDI technology has helped reduce the size and weight of electronic devices like cell phones, tablets, laptop computers, and touchscreen products while improving their performance.

- Aerospace: HDI PCBs are used in electronic designs for missile systems, aircraft, and defense applications, providing reliable operation in extreme environmental conditions.
