In modern PCB manufacturing, even small design choices can significantly impact performance, reliability, and cost. One such critical detail is solder mask over via (SMOV)—a
In modern electronics, PCB via holes play a critical role in connecting different layers of a printed circuit board. As electronic devices become smaller, faster,
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
