What is HDI PCB?
High-Density Interconnect PCB
An HDI PCB uses finer traces and smaller microvias than standard boards, packing more connections into less space for compact, high-performance devices.
HDI is what makes smartphones, wearables, and dense modules possible. It relies on microvias, blind and buried vias, and thin dielectrics — techniques that demand careful stackup planning and DFM to stay manufacturable.
