asymmetric pad shape. help!

vnick

Hi,

I need to built an footprint with asymetric pads. The required pad has oblong at an edge and rectangle at the other edge (QFN package).

Could somebody help me!

    Hi Steve,

    It's a good point.

    Unfortunatelly, command Add rarc doesn't work (I use vers Orcad16.0). In that case I can't make the round side of the pad.

    Do you have other suggestion?

    Regards,

    When you are in the add shape command change the options menu from lines to arcs depending on what you want to draw. This means you can draw a line, then change to arc, draw the round side then change back to line and so on....

    It works. Many thanks!

    Do you know how could I add soldermask/pastemask to that pad?

    Using the same method. Just have 3 shapes, pad, pad_mask and pad_paste and in pad designer define the shape at each layer.
