    Hole Size in Padstack Question

    rflowers

      Hi yall

      Just noticing that the hole circle in the padstack is not matching the correct size for the hole for a thru-hole padstack.

       

      The pad diameter matches exactly for the pad itself (55 mil pad in the padstack parameters is measuring exactly 55 mils diameter

      in the footprint), but the hole diameter of 30 in the padstack parameters is coming out at about 33.5 mils when you measure it in

      the footprint.  Why is it not exactly  30 mils like it is in the padstack?  Why the extra 3+ mils when you measure the hole in the footprint?

       

      Thanks!
