6 layer HDI PCB with microvia technology
$36.50
6 layer HDI PCB is a type of multilayer circuit board with six conductive layers, which adopts high density interconnect technology to increase the routing density per unit area. This technology enables circuit boards to integrate more components and support complex tracing routing by using microvias, blind/buried vias, and finer trace widths and spacing. Compared with four layer HDI PCBs, 6-layer HDI PCBs have extra layers to increase routing flexibility, reduce via usage, and save space.
