What is HDI PCB

HDI PCB is a modern technology developed in the PCB industry in the late 20th century. HDI PCB manufacturers are springing up like mushrooms in China. Multi-layer HDI PCB manufacturers adopt incremental method and micro-blind buried hole manufacturing, which is composed of the following different holes:

Micropores: In HDI PCB manufacturers, holes less than 6mil (150um) in diameter are called micropores.
Buried hole: the hole buried in the inner layer, not visible in the finished product, is mainly used for internal line conduction, can reduce the probability of signal interference, maintain the continuity of the transmission line characteristic impedance. Since burials do not take up the pcb's surface area, it is easy for HDI PCB manufacturers to place additional components on the pcb's surface during manufacturing.

Blind hole: refers to the conduction hole that HDI PCB manufacturers use in the design to connect the surface layer to the inner layer without passing through the entire board.

The drilling of traditional pcb board is considerably affected by the drilling tool. When the borehole size reaches 0.15mm, the total cost for HDI PCB manufacturers becomes particularly steep and difficult to increase. Instead of relying on traditional mechanical drilling, HDI PCB manufacturers use laser drilling technology, sometimes called laser plate.

The hole diameter of HDI PCB board is typically 3-5mil(0.076-0.127mm), and the line width is commonly 3-4mil(0.076-0.10mm). The pad size can be considerably reduced for HDI PCB manufacturers and additional lines can be distributed per unit area, resulting in superior density interconnections.The emergence of HDI PCB technology has adapted and promoted the development of the FPC/PCB industry, enabling HDI PCB manufacturers to arrange more dense BGA, QFP, etc., in their designs. At present, HDI PCB technology has been widely used, and the development of HDI PCB technology promotes the development of chip technology, which in turn promotes the improvement and progress of HDI PCB technology, and also promotes the gradual increase of domestic HDI PCB.
