Q1: What is a Via?
A1: A Multi-Layer PCB. Connecting multiple layers of a board makes it possible to reduce the size of the PCB, as layers can be stacked. A via is constructed by placing copper pads on each layer of the PCB and drilling a hole through them. The hole is made conductive through electroplating or by placing copper cylinders directly in the drilled holes.is used to make an electrical connection between the layers of a
