    How to define different via landing and capture pad size?

    mdt

      Hi,

       

      how can I define Vias spans with a larger via capture pad than via landing pad? I only managed to influence the top, bottom and inner layer via pad diameters. But this is not working for me because I need multiple layers of hdi vias.

       

      Example for clearification:

      * On via span 1-2 I need 350 µm via capture pad on layer 1 and 250 µm via landing pad on layer 2 (working)

      * But on via span 2-3 I need 350 µm via capture pad on layer 2 and 250 µm via landing pad on layer 3 (not working)

      * And on via span 3-4 I need 350 µm via capture pad on layer 3 and 250 µm via landing pad on layer 4 (not working)

       

      Does anyone has a solution for this?

       

      Regards, Michael
