    There are 18 pads in this padstack (the number of elements in the pad list), and information about some of the pads is shown in the image below

    Total Number of pads = 3* Number of Layers + Soldermask_top + Soldermask_bottom + pastemask_top + pastemask_bottom + filmmask_top + filmmask_bottom

    Number of Layers are 4 (TOP, GND, VCC, and BOTTOM) =3 *4 + 6=18

    Note that for every layer, three types of pads are defined: Regular, Thermal, and AntiPad. You can confirm it from the Padstack Editor Design Layers

    For the maskLayers, the information about the pad from Allegro SKILL and Padstack Editor is shown in the image below:
