Introduction to HDI Circuit Board
High - Density Interconnect (HDI) circuit boards are a type of printed circuit board (PCB) that feature a higher wiring density per unit area compared to traditional PCBs. They are designed to meet the increasing demand for miniaturization and high - performance in modern electronic devices. HDI boards typically use microvias, buried vias, and blind vias to achieve a more compact design and better electrical performance. These boards are widely used in smartphones, tablets, laptops, wearables, and other high - end electronic products. The manufacturing process of HDI circuit boards is more complex and requires advanced technology and equipment, which makes the production cost relatively higher than that of traditional PCBs. However, the advantages of HDI boards in terms of size reduction, signal integrity, and reliability make them an indispensable component in the development of the electronics industry.
