    Problem with SOT-89 thermal pad connection Reply

    I'm having a problem with Layout when using a SOT89 footprint, and trying to connect to the thermal tab. The footprintshows it as being connected to the centre pin, but the DRC will not allow me to connect to it, causing a lot of issues when routing. Anyone have a workaround for this problem ? Currently I turn off DRC, make the connection and when running the DRC at the end of routing, ignore that error. Seems a bit of a silly problem. Any ideas ?

    What type of DRC are you getting? That should give you a better clue as to what the problem could be. Do any of the lines connecting to the SOT89 pins have very large line to line spacing rule constraints?

    Hi

    DRC may be because of route keepout near the component.

    please post the DRC Error.
