Tg170 Multilayer Board(3+4+3) HDI PCB Wearable Devices

♦ What is HDI PCB?

HDI (High Density Interconnect) PCB is a high-density circuit board constructed by micro blind buried via technology, and uses a build-up process to achieve three-dimensional interconnection of inner and outer layer circuits. The core of its manufacturing lies in the use of laser drilling and electrochemical hole filling processes to form micron-level conductive paths between layers, so that each layer of circuit can be vertically connected without relying on traditional through holes. Ordinary HDI uses a single-layer structure, while high-end products are stacked through multiple layers, combined with advanced technologies such as stacked holes and laser direct forming, to further improve circuit density and electrical performance.
