High Density Interconnect (HDI) PCBs feature a higher line density than traditional PCBs, utilizing microvia technologies and materials with low dielectric constants to enhance signal transmission. These advanced boards incorporate features like laser-drilled microvias, stacked vias, and fine lines to support the dense arrangement of miniaturized components. Essential for devices requiring high-speed signal integrity and reduced electromagnetic interference, HDI PCBs are widely used in smartphones, laptops, and automotive electronics, driving forward the miniaturization and performance enhancement of modern technology.
