What Is an HDI PCB vs a Standard Rigid PCB? Microvias, Fine Pitch, and Medical-Grade Density
Quick Summary An HDI PCB (High-Density Interconnect PCB) achieves routing density that a standard rigid PCB cannot by using microvias, finer trace/space, and build-up layer structures that support fine-pitch components. In U.S. medical devices, HDI is most valuable when the design must shrink, carry more channels, or improve signal integrity while staying reliable under thermal […]
