Blind vs Buried Vias: A Comprehensive Guide for PCB Design

A printed circuit board (PCB) is made up of layers of copper foil circuits stacked on top of each other, and the connections between different circuit layers rely on vias. If the holes drilled by a drilling machine or laser are left as is, they will not conduct electricity, because the surface of the original drilled hole is only resin, which is not conductive. Therefore, a layer of conductive material (usually copper) must be plated on the surface of the drilled hole. In this way, current propagates ......

The Impact of Inner Layer Residual Copper Rate on Board Thickness

When we were kids, we heard the children's story "The Crow Drinks Water," where a crow raises the water level by dropping stones into a fixed amount of water in a bottle. The same principle applies to multilayer PCB lamination, where during high temperature and high pressure, PP sheets flow in a liquid state to fill the gaps between the layers. This process is called "resin filling." As seen in the diagram, when the copper coverage in the inner layer is minimal, PP sheets of the same thickness need to......
