Are Polygon Footprints With Eagle Possible?

Community PCB Design

All,

Designing a board for an LED project I’m doing.

The driver is LGA, and combines pins for one signal.

For the pins that are square or rectangular it’s okay,

Because I can just spot a SMD pad with the proper

Dimensions and it works well.

But when the pins are not and require a different shape, I

Can’t figure it out, ha ha.

Attached is a photo from the data sheet that shows the

Suggested copper layout.

What I’m currently doing is putting a rectangular pad on the edge, turning off the stop and cream for the pad, then filling the rest with a polygon of copper. I can then attach a wire to the net in board layout.

But for the ground when I do a ground fill it only attaches to the pin inside the polygon not all of the polygon layout for the ground. And I need to connect all of it for good heat management.

How do you guys do LGA ICs.

Thank you all for your help.

Attached are pictures of in schematic and layout of what I’m trying to do.

Thank you.

Would it be better to do it in board layout rather than library editor?

I gave up on EAGLE when DesignSpark PCB was released.

I am still not exactly sure what it is you’re trying to do…??
