HDI pcb boards support more electrical connections per unit area than traditional single-layer boards. This is mainly due to the use of multiple layers as interconnects between layers in both laminated and blind holes.
High Density Interconnect (HDI) is a technique for creating high speed and high density PCBS. HDI uses blind and buried holes to increase signal density and thus improve the performance of printed circuit boards.
HDI technology allows designers to drastically reduce the size of the circuit, while still ensuring the required reliability and signal integrity. For engineers, the challenges to be faced are particularly tough, mainly related to the fabrication process.
Maintain the integrity of signal transmission and prevent the "ground projectile phenomenon" caused by the division of ground wire.
