Capacitive Touch Button

marialemv

Hi all,

I am trying to make a footprint for a simple capacitive touch button with a via pin. I made a circular shape on the top plane and added the pin but I am getting DRC error: thru pin to shape spacing.

I tried editing the constraint value to 0, and also tried a connector with a via instead, but I need the via to be my pin and I can't get rid of the DRC error.

Can someone please help me out?

    Just a comment about this. You will ALWAYS see a DRC in a package symbol when you place pins, vias, clines and shapes that overlap because the package has no netname assocaition and the DRC system reports this. Save the package symbol with DRCs then once this symbol is used in a design with a netlist, the shape/via/clines takes on the same netname as the pin and no DRC will be shown.

    The only MFG problem you may see per your design example would be- If your board needed wave soldering. For solder re-flow none. The solder may bubble up thru your thru-pin if not covered by the solder mask during waving. So, if you can live with this, then problem.
