China Wholesale Circuit Board Assembly Pricelist - 14 Layer Blind Buried Via PCB – Huihe
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,... -
