2-sided footprint that's not a mirror image

Postby fedor » Wed Jun 11, 2014 5:01 pm

I'm trying to make a footprint for SMA board edge connector (e.g. DigiKey P/N WM5536-ND). the connector has 3 solder pads on top side and 2 on the bottom. I search the forums and still cant figure out how can I make such a footprint. Could you point me in a right direction?

You will need to make two footprints. One for the top and another for the bottom pads. Once you have the footprints place them on you layout.

  1. Move the top pads into position.
  2. Mouse over the footprint for the bottom layer pads, right click and select opposite side. This will mirror the footprint and place it on the bottom layer.
  3. Move the footprint into position.

Sal,

Thanks for info! Do I understand it right that there will be one footprint on the layout attached to actual schematic part (say, the top footprint) and a second (bottom) foot print which is not part of the schematic?

Both sides of the part, top and bottom footprint will be represented on the schematic. If you don't create a symbol for the bottom pads one will be created for you on the schematic sync page. It's up to you how you want to see it on your schematic.

Thanks again!

How do I treat edge connectors in PCB123? When I place pads at the board edge, I get an error that required spacing between objects and board edge is 0.0125". Should I ignore it or move pads away from edge?

You probably don't need pads right up to the edge, but if you do you can ignore the warning. Pulling the pads back 10 to 20 mils will resolve the error.
