HDI PCB, or high-density interconnect printed circuit board, uses fine conductors and compact interlayer connections to fit more wiring into a given area. Laser-drilled microvias and thin buildup layers help connect dense component pads without using a full-thickness hole at every connection. The design question is whether those features solve a routing constraint worth the added processing. Start with package geometry and layer access, then compare constructions.
