Mech pins use antipads as route keepout
WebDrill to Metal DRC Drill hole to metal-based checking covers both holes associated with circuitry (pins and vias) and holes associated with mechanical pins, where the antipad can be used as an implicit route keepout area. Drill holes are commonly referred by their plating category; plated or non-plated. WebDec 8, 2011 · Hello. I've got a problem with copper pour and routing keepout. I need to make PCBs where is not allowed a connection on top layer directly on the pads, so I put route keepout areas on top layer directly in the pattern definition. This usually works fine with the routing part, but as soon as I copper pour the top layer, the pads are connected ...

WebNov 17, 2024 · Via with antipad and an NFP on a single-ended net. A Low Frequency Model (up to 3-5 GHz for Dk = 3 to 4) At low frequencies, there is a simple model that can be used to approximate via behavior. The point in applying a specific antipad is so that the via impedance can hit a specific target.
WebAnti-pads are void areas around a plated through-hole that stops other signals from connecting to the particular hole. Some PCB manufacturers use anti-pads to avoid short circuits between neighboring vias. You can also use Antipads on landing pads and internal plane vias.
