How to define a socket header between PCB and plugin module?

We have designs that use plugin DIP modules similar to arduino nanos where a PCB has two parallel rows of headers plugs into my design. In my schematic I create a symbol for the actual part with all the pin functions and typically create a footprint with both rows so that the spacing and place bound is fixed during layout. This would all be fine if we just solder the module in, but we really want two rows of socket headers to plug the module in. We also use CIS so the database part calls out the actual module to be ordered in the BOM. I'm not seeing how to properly call out the socket headers.

Options I've considered are: 

1) add a manufacturer part for the socket header to the module database part so the BOM will call out headers instead of the module, then create another database part for the module itself to be called out in the BOM for purchase

2) add the socket header to the part as a mechanical part and call out some assembly instruction to use the header (seems wrong as I type it)

3) place the header parts as a separate footprint on top of the module footprint

Is 1 the cleanest option?

On a related note, if I socket header parts that are the exact number of pins per row, how do I tell CIP that it will need a qty of 2 for that one database part?

  • You mention that you have CIP so open the part in CIP and you should see a Mechanical Parts tab for each part. You can add Mechanical Parts to your database (Mechanical table) then add these to your header part. When you output a BOM enable the "Output Mechanical Part Data" checkbox in CIS - Reports - Standard and they are included.

    I can see how using mechanical parts will allow calling out 2 headers in the BOM. In this case, the module would be called out in the BOM with a refdes like U1 while the headers are not directly associate to a footprint. So would you use assembly notes to make sure the headers are applied to U1 instead of the module being soldered directly?
