An annular ring is the copper area surrounding a plated via on a PCB. It establishes a solid connection between the via and copper traces.| Sierra Circuits
Drilling is the most expensive and time-consuming process in PCB manufacturing. A small fault in the drilling process leads to a great loss.| Sierra Circuits
PCB via current carrying capacity can be regulated using the process of tenting, plugging, and via current calculators.| Sierra Circuits
Vias are miniature conductive pathways drilled into the PCB to establish electrical connectivity between the different layers.| Sierra Circuits
