As component sizes shrink, printed circuit board manufacturers have
adapted to changing trends. Make the PCB smaller, higher density,
more components, and faster. The birth of HDI solves this problem
very well. High-density interconnected PCB circuit boards, blind
hole plating, and second-time pressing are all HDI boards, which
are divided into first-order, second-order, third-order,
fourth-order, and fifth-order HDI. The high-density interconnect
PCB circuit board is a relatively high line distribution density of
the circuit board using microblind and buried via technology.
High-density interconnection HDI is just a PCB circuit board with
more interconnections and occupying the smallest space.
