HDI PCB

HDI PCB stands for High-Density Interconnect Printed Circuit Board. It is a high-end circuit board that delivers significantly higher component and interconnection density than traditional PCBs. By leveraging advanced manufacturing processes such as micro-vias, fine-line patterning, and multi-layer stacking, HDI PCBs enable smaller vias, finer traces, and increased layer counts, supporting more compact and complex electronic designs. This makes them ideal for space-constrained applications, including smartphones, tablets, and other portable devices, as well as medical equipment, aerospace and defense systems, automotive electronics, industrial machinery, and consumer electronics. In short, HDI PCBs are essential components for any application requiring miniaturization, high-density interconnects, and superior performance in limited space.
