Frequently Asked Questions

What is HDI in PCB manufacturing?

HDI (High-Density Interconnect) PCB manufacturing refers to the production of circuit boards with a higher wiring density per unit area than conventional PCBs. HDI boards use microvias, fine lines, and advanced layer stackups to achieve miniaturization and improved electrical performance. They are commonly used in smartphones, medical devices, aerospace electronics, and other compact, high-performance applications.
