HDI PCBs
What Is HDI PCB?
HDI PCBs stand for High-Density Interconnector Printed Circuit Boards. It has a higher wiring density per unit area than conventional printed boards. We can get features like high-layer count and fine-laminated boards. HDI PCBs also have sophisticated lines & spaces, minor vias & capture pads, and higher density of connection pad density.
HDI PCBs have great electrical performance, lighter weight, and smaller size of equipment. Therefore, the HDI circuit board has become the better option for costly laminated and high-layer count circuit boards.
Other Advantages:
High-speed, small size, high-frequency, advanced technology, high-density.
Application & Advantages
Though HDI PCB has a complex manufacturing process, it has a wide range of applications. It can be used in various industries, such as electronics and medical. The lighter weight and small size give it appropriate reasons to be installed in miniature equipment.
HDI PCB is consumer-driven and fit for more delicate and sophisticated electronic equipment. Nowadays, people prefer agility electronic equipment because of its convenience and lightweight. HDI PCB makes the equipment small and smart. It is thin, light, and features high-end technology and high-speed operation capability.

What is HDI Technology?
HDI technology is a high-end technology used to manufacture HDI PCBs. This printed circuit board features high density and good performance in circuit interconnection. Therefore, people also know it as a high-density interconnect PCB. Nowadays, HDI PCBs have become one of the fastest-growing technologies in the printed circuit board industry.
According to the vias, HDI boards can be divided into six different types:
- Face-to-face through vias
- Through vias and buried vias
- Two or more layers with through vias
- Non-electrical connection and passive substrate
- Coreless construction with layer pairs
- Alternate constructions of coreless constructions with layer pairs
- HDI Printed Circuit Board Manufacturing
Advanced HDI technology Methods
- Via in-pad process: In this process, HDI PCB manufacturers place bias on the surface of the flat lands. And then, it fills the vias with conductive or non-conductive epoxy. Later, it is capped and plated over. The result makes the via invisible.
- Via fill technology: Professional HDI PCB manufacturers use specific materials. These include silver-filled, conductive epoxy, non-conductive epoxy, electrochemical plating, and copper-filled..
- Non-conventional HDI PCB building: HDI PBCs must combine more lines and annular rings on a thin, high-density board. Therefore, to create advanced HDI PCBs, one should make lots of effort on the board design and manufacturing equipment.
- Laser drill technology: A laser beam of light 20 microns in diameter can create the smallest vias on the surface of HDI PCBs. This high-energy light is precise & efficient and can cut through metal and glass to make a tiny via hole.
There may be some misunderstandings against Chinese PCB manufacturers. Some may think that they provide cheap but inferior products. Actually, no matter what country it is, a high price doesn’t always mean high quality. It depends on various factors. However, in most cases, a high price may determine the high quality of the product. They typically come with durable PCB materials and sophisticated PCB designs. In addition, they resemble excellent PCB manufacturing and assembly equipment. If the PCB company has its R&D basic, it might price relatively high for its products.
There are a few reasons for the lower product prices of Chinese manufacturers. It is not the unreliable product quality or inferior PCB fabrication and assembly equipment but the local market and policy. Reasons why you should choose Chinese HDI PCB manufacturers are:
A crowded market stimulates advanced technology
With over 15 years of experience, the Chinese PCB market has a well-established system of PCB services. Fierce competition in this market encourages Chinese PCB manufacturers. It enhances its manufacturing technology to offer competitive products continuously. However, market dynamics make prices generally lower than in Europe.
Lower-cost labour with efficient production
China’s competitive employment market also produces lots of efficient labour with lower costs. China nowadays can achieve mass PCB manufacturing and assembly in a highly efficient way. It lowers the production time and cost. Besides, it provides an affordable price with the same quality as other developed countries.
High-quality PCB service
As the PCB market matures, Chinese PCB manufacturers can provide satisfying services. Their full-service includes full-service from PCB manufacturing to deliver only your requirements online. The Internet provides a chance for every PCB company to buy PCB online.
