What is HDI PCB? HDI PCB is the name of a printed circuit board with a large number of interconnects. In other words, it means a PCB with more components and circuits per unit area than a normal PCB. This complex design is the basis of many electronic products today, from mobile phones to computers and…
1.What is HDI circuit boards HDI (High Density Interconnector) board, or high-density interconnect board, is a circuit board with a relatively high line distribution density that uses micro blind buried hole technology. It contains inner and outer layer circuits, and then uses drilling and metallization processes in the holes to achieve the connection function between the…
What is an HDI stackup? HDI stands for High Density Interconnect. An HDI printed circuit board is characterized by a high density of components and routed interconnections. HDI design is inherently a high-performance design. It features fine lines and spaces (≤100µm), small vias (<150µm), small capture pads (<400µm) and high connection pad density (>20 pads/cm2). The small…
