In PCB drilling, a via passing the hole diameter inspection does not guarantee that subsequent copper plating processes will be trouble-free. There are usually three main causes: resin smear caused...

There is a gap between Nominal Model and Fabrication Reality. While high-current PCB engineers model vias as ideal cylinders in EDA simulations (e.g., Altium, Ansys), high-current PCB factories pro...

Signal traces are purely about a basic electrical continuity—clean DC connection, not raw flow capacity. But high-current vias is the power rail, it serves as active components of the power delive...

“How much current can this trace carry” is a main part of the topic about high-current PCB. This can easily lead to the impression that high-current PCB design is mainly about designing traces to...
