Unlike traditional PCBs, HDI PCBs leverage microvias (blind, buried, or through vias with diameters as small as 50μm), fine-pitch traces (≤3mil), and stacked/sequential lamination to pack more functionality into smaller spaces . Technical Evolution of HDI PCB The journey of HDI PCB began in the late 1990s, driven by the mobile phone industry’s demand for thinner, more compact devices. Early iterations focused on single-layer microvia structures,
- [Flexible PCB Assembly](https://hcjm-pcba.com/pcb-assembly-services/flexible-pcb-assembly/): Flexible PCB Assembly HCJMPCBA’s Precision Solutions for Advanced Electronics Introduction: What is Flex PCB Assembly?  Flexible PCB assembly (or flex pcba) is the process of integrating electronic components onto flexible printed circuits (FPCs) to create functional, bendable electronic modules.
