PCB Land pattern with multiple shapes

Frozen001
Frozen001 over 6 years ago

I am trying to make a PCB land pattern for an RF shield that is mounted using special clips.

the clips are here:

https://hollandshielding.com/PCB-shield-mounting-Ultra-tiny-clip-UTC
https://hollandshielding.com/PCB-shield-mounting-Ultra-tiny-corner-clip-UTCC

I originally figured I could just create a custom symbol for the land pattern, but that does not work as you can only have one shape.  Ideally, I want a footprint that has the 4 corner clip patterns and the straight patterns all in one footprint that only has to have one pin in the schematic to ties those to ground.

Any thoughts on how to best do this?  I also need to have the keep outs in specific areas near the clips and where the shield would be near the PCB.

    If you don't need to connect to it (and will rely on the part making contact to the three pads) you can either make these mechanical pins so you then only have one pin the schematic. You can also place one pin down in a package symbol and then draw copper shapes for the other sections. Keepout areas can be drawn in the package symbol.

    Thanks for the input.  I think because I want them all connected to ground I may just run a small slice of copper to connect them all and call it a day.  That way it technically is "one" shape, but still has the distinct shape needed to match the recommended land pattern.
