PCB vias can transfer electrical signals between different layers, and they are an indispensable part of complex circuit design. However, the process of drilling and
PCB vias are the electrical connections between layers. Vias are handled in the following ways: PCB vias be covered: Standard: Over-line holes must be covered,
When designing a PCB, how to choose the via size? There are two voices.One voice said: choose 10-12mil via,Large vias are not helpful for heat
Most of PCB manufacturers use Al sheet to plug vias.We use blank net to make solder mask and plug vias after many experiences, it’s stability
