HDI Special Feature - From Through-Holes to Micro-Holes: The Complete Design Logic for HDI Blind and Buried Vias

Modern electronic products—such as 5G base stations, AI chip packaging, and wearable devices—pursue smaller form factors and higher functionality. Traditional large-sized through-holes cannot meet the demands of high-density routing. High-Density Interconnect (HDI) boards utilize blind and buried vias as core technologies to maximize effective area utilization and enhance signal integrity.

HDI Special Feature - Case Study【Must-Read for RD】: 8-Layer HDI Stacking Strategy: Practical Optimization Guide for High-Speed PCBs from SI/PI to Warpage Prevention

As electronic products evolve toward greater thinness and higher performance, the design challenges for printed circuit boards (PCBs) continue to increase. Multilayer high-density interconnect (HDI) boards have become the mainstream solution for high-speed systems. The core feature of HDI lies in the implementation of blind and buried via technology, which effectively increases routing density, reduces board thickness, and delivers excellent high-frequency performance. Among these, 8-layer HDI boards strike a favorable balance between functional complexity and cost, finding widespread application in high-speed digital and communication-related circuits.

HDI Special Feature: A Deep Dive from First-Order Fundamentals to Third-Order Limits

In today's era where electronic products are racing toward ultra-thin designs and high performance, HDI (High Density Interconnect) boards have become the “nerve center” connecting the microscopic world. Unlike traditional PCBs, the “layer count” of HDI boards is not merely a simple stacking of layers. Instead, it represents a unique technological tier determined by the arrangement of micro blind vias, the number of lamination processes, and the frequency of laser drilling.
