Domepad eagle lib part

Former Member

image

Hi,

 

The image above is a so called "domepad", a landing pattern for a button.

But does anybody know how to make this correct in a eagle library element?

 

The inner part and outside line should be functioning as different pin's.

 

The problem is that i have to draw with copper to get this shape, else i need to use many different pads.

But this way i get endless DRC errors like clearance and overlap.

And i need to choose a central point (The physical pad for in library) where the connection is made.

 

Does anybody know how to make a element where i have 2 connection points in the schematic and a DRC free footprint?

 

Thanks in advance,

    Have a read of the manual Section 8.14 Arbitrary Pad shapes.

    The manual is in the docs folder of your installation. This will give you

    an understanding of the requirments for arbitrary pads.

     

    Attached is a rough library of what you are asking for. Revese engineer it

    to understand how its done especially CONNECT where each pin is connected

    to many pads. The first pin pad connection is made with the CONNECT button

    and subsequent ones made with the APPEND button.
