https://www.raypcb.com/wp-content/uploads/2022/04/hdi-PCB-Manufacturers.jpg1920800Introduction In printed circuit boards (PCBs), vias provide electrical connections between layers of the multilayer board. While basic vias span the entire board thickness, advanced PCB technologies enable creating buried vias that connect only between internal layers without reaching the outer surfaces. This article provides an in-depth look at buried vias, discussing their definition, fabrication […]
