The Companion Guide to... Ultra High Density Interconnect (UHDI)

The Companion Guide to… Ultra High Density Interconnect (UHDI) examines how UHDI is transforming PCB design and manufacturing. As trace widths decrease from 25 microns to 5 microns, UHDI allows for finer geometries, tighter impedance control, enhanced RF performance, and fewer layers. This guide highlights key differences between HDI and UHDI, advanced via structures, copper-filled microvias, material innovations, and solder mask considerations. Designers gain greater routing freedom while assuming stricter process discipline and must collaborate early with fabricators. Ideal for RF, high-speed, aerospace, and miniaturized applications, UHDI offers clear improvements in size, weight, power, reliability, and overall electronic performance.
