    PADS layout - How to draw a masked part in the middle of a decal pin

    luca.rivano

      Hello everybody,

      i am creating a custom PADS decal, modifying the central square pin (3x3mm) of a standard QFN decal.

      I would like to draw on it a central solder mask part (2x2mm), in order to let a bare copper frame on the pin boundary.

       

      The final purpose is to place a bare die on the central insulated part and make a wire bonding between the die itself and the other QFN pins around.


      Can anyone suggest me how to draw a masked part in the middle of a pin?
      Thank you in advance.
