Arbitrary Pad Shapes

e14 Contributor
e14 Contributor over 14 years ago

Hi,

 

I have a FET with the pad layout shown in the attached drawing.  I've tried

a few things but can't get past the "Package ... contains an invalid

polygon."

 

First I tried having 4 pads all connected with a polygon in the shape of an

"H".  That didn't work.

 

Next I tried a single pad with the "H" creating the other 3 pads with the

polygon.  That did't work.  In addition, if I make the polygon width too

large, it doesn't fit, too small, Eagle complains, and anything in the

middle leaves the corners of the other 3 pads rounded.

 

Next I tried a single pad but creating the pad with wires.  This doesn't

work either and I have the same problem with the rounded corners.

 

Finally I tried a single pad and making the "H" with overlapping rectangles

on the top side.  And guess what?  That didn't work either.

 

What is even more confusing is for the last 2 attempts there aren't even

any polygons in the package (and I have only this one library turned on so

there aren't any other conflicting packages).

 

I'm baffled as to how to do this.  Any ideas?

 

Thanks,

 

Dave

    And I just tried creating 6 pads, overlapping the left 4 with a polygon,

    then connecting the pads with wires.

     

    That didn't work.
