A Brief Primer on HDI PCB Manufacturing
HDI is the abbreviation for high-density interconnector. It refer to a technology for manufacturing printed circuit boards (PCB). Based on traditional multi-layer printed circuit board manufacturing technology, HDI introduces a new process of foil-RCC (Resin Coated Copper) laminate, supplemented by laser drilling, horizontal/vertical PTH (Plated through Hole) wet process and other processes produced by the blind hole/multi-layer buried PCB circuit boards.
