About Blind Buried Via PCB
Blind vias and buried vias are two ways to establish connections between layers of printed circuit board. The blind vias of the printed circuit board are copper-plated vias that can be connected to the outer layer through most of the inner layer. The burrow connects two or more inner layers but does not penetrate the outer layer. Use microblind vias to increase line distribution density, improve radio frequency and electromagnetic interference, heat conduction, applied to servers, mobile phones, digital cameras.

The advantage of blind Vias and buried Vias for engineers is the increase of component density without increasing layer number and size of circuit board. For electronic products with narrow space and small design tolerance, blind hole design is a good choice. The use of such holes helps the circuit design engineer to design a reasonable hole/pad ratio to avoid excessive ratios.
