[PCB_FORUM] Re: How to connect Two thru-hole pads that are placed same location.

With OrCAD I Delete pins from symbol and what remains is only graphic
lines. Like this it wont appear in netlist but it has P/N
which can be output into BOM. I am not sure if is possible with Concept?

Our schematic feeds the BOM. Must have both in the schematic for different
populations.

      IMHO - The best way to would to let the BOM control which connector
      is populated and only have one connector on the schematic.

      In some backplane applications, the pins are really short and the
      primary side connector and the secondary side connector share the
      same hole.
      On this type of backplane we have the BOM control the connector and
      the schematic shows only one connector, even though both connectors
      (top, bottom) are populated.

      Mark,

      I never have done this, but it seems like it might work.

      Move one of the connectors off board and make the connections, then
      move the connector back into position.

      If I had to guess, Allegro will keep the connection.

      Just an idea, Hope this helps.

      Subject: [PCB_FORUM] How to connect Two thru-hole pads that are
      placed same location.

      We have two thru-hole connectors placed on top of one another. One
      populated, one not.
      PROBLEM: We can not get rid of rats, because two pins / pads at same
      X:Y.

      Any ideas how to get connection to both pads?

      We decided to remove net names from one of the connectors in the
      schematic, to allow us to connect to one pad on board. Then waive
      DRC's.
      We are using V.15.7 and Concept front end.

      Regards,
      Mark
