WebThe traces are 0.254 mm in width. Adding a via between pads 1 and 3 and connecting the traces to them complete the ring, but is there another way to create the guard ring? Also, how do I ensure that no soldermask covers the ring? Does the ring need to not have soldermask (be exposed copper as shown in this example board) in order to work properly? WebSep 22, 2016 · Guard traces are traces without solder mask (with exposed copper), which are meant to stop creepage current across the surface of the PCB.
