What is HDI PCB

HDI : High Density Interconnection Technology.

Non mechanical drilling, micro blind hole size less than or equal to 150um (6mil), the trace L/S between inner and outer layers less than 4mil, pad diameter ≤ φ The 0.35mm increase layer method for multi-layer board production is called HDI board

Compact design

The combination of micro vias, blind vias, and buried vias greatly reduces board space. With the support of HDI technology, a standard 8-layer through-hole PCB can be simplified into a 4-layer HDI PCB but with the same functions.

Excellent signal integrity

With smaller vias than normal PCBs, all stray capacitance and inductance will be reduced. Combining the technology of bonding vias and vias in pads helps to shorten the length of the signal path. These will lead to faster signal transmission and better signal quality.

High reliability

HDI technology easier wiring and connection, and provides PCBs with better durability and reliability under hazardous conditions and extreme environments.

Save costs

If the traditional pressing process is used and the board layer exceeds 8 layers, then more manufacturing costs are required. But HDI technology can reduce costs and maintain functional purpose.

Products application

HDI is currently widely used in mobile phones, digital (camera) cameras, MP3, MP4, notebook computers, automotive electronics and other digital products like medical equipment, among which mobile phones are the most widely used. HDI boards are generally manufactured by the build-up method. The more layers are built up, the higher the technical grade of the board. Ordinary HDI boards are basically one-time build-up, and high-end HDI uses two or more build-up technologies, and at the same time adopts advanced PCB technologies such as stacked holes, electroplating and filling holes, and laser direct drilling. HDI multi-layer circuit board production.

Industry information

The development of HDI PCB technology has brought unprecedented design freedom and flexibility to engineers, allowing more components to be placed on both sides of the original PCB as needed, while allowing smaller components to be placed together. This means that HDIPCB ultimately results in faster signal transmission as well as enhanced signal quality.

HDI PCBs are widely used to reduce the weight and overall size of products, as well as enhance the electrical performance of devices; often appear in mobile phones, touch screen devices, laptops, digital cameras and 4G network communications. HDI PCBs are also prominent in medical equipment as well as various electronic aircraft components.

Most High Density PCB have small tracks width and gap min. 3/3mil, which let engineers realize more functions on one limited dimension PCB.
