HDI PCBs allow engineers to fit more functionality into smaller spaces by using fine lines and spaces, microvias, blind vias, buried vias, via-in-pad structures, and sequential lamination. These features make HDI important for compact, high-performance electronics such as smartphones, wearables, laptops, medical devices, automotive systems, aerospace electronics, and high-speed computing hardware.
As electronics continue to shrink while performance expectations increase, HDI PCB technology will remain central to advanced product design.
