Annular Ring Explained by a PCB Manufacturer | Sierra Circuits
2020年8月18日 · An annular ring is the area of copper pad around a drilled and finished hole. The finished hole we are talking about here is nothing but a copper-plated via. All around this via there should be enough copper to form a solid connection between the copper traces and the via in a multi-layer PCB.
Annular Ring: A Comprehensive Guide for PCB Design
2024年8月29日 · What is an annular ring in PCB design? An annular ring in PCB design is the ring-shaped area of conductive material surrounding a drilled hole (via). Its role is to ensure reliable electrical connections between different PCB layers and to provide mechanical support for components and vias.

2018年2月13日 · Annular rings come into play when considering the physical location of the drill holes through each via trace. There are a few factors that come into play when determining the proper annular ring size for your application.
Everything About PCB Annular Rings - WellPCB
2024年7月26日 · What is the PCB annular ring? An annular ring is an area of the copper pad that sits around a finished and drilled hole. The dead point here is the through-hole copper plating. In all around this via, there needs to be sufficient copper. Enough copper enables the formation of reliable connections between the via and the copper traces.
Understanding the Importance of Annular Rings in PCB Design
The size of the annular ring in a PCB is critical for ensuring reliable electrical connections and mechanical stability. An adequate annular ring width is essential for creating robust solder joints, preventing breakout during drilling, and reducing the risk of pad lifting.
