Buried Via PCB Assembly
Vias, that is, copper plated holes, play a key role in the interconnection between layers in a printed circuit board. Generally speaking, vias in PCBs can be classified into the following categories: through-hole via, blind via and buried via. Blind/buried vias are widely applied in SMT (Surface Mount Technology) just to compensate for disadvantages of through-hole vias.
Buried vias connect only inner layers inside printed circuit board so that they are invisible just from the outer appearance of a PCB since they are internally "buried".
