Mismatch in components location between pick/place file and OBD file

Hello All

Greetings..

I have designed a PCB with the components on both TOP and bottom layer . Generated OBD++ and pick/place file. But the Assembly house is reporting that the ODB++ file generated from PCB is showing that all the component location is TOP on their tool (CAD CAM Professional). where as the pick/place file shows the bottom components correctly as "m" orientation.

Not sure why the OBD++ file is showing wrong positions. Kindly help.

Tool: PCB Designer professional 16.6 ( with ODB++ inside)

Regards

Hi. I've never encountered that problem with ODB++, sorry. I'm currently running 17.2 and still no issues. I suspect it's the assembly house's issue, not yours.

When you generate the ODB++ do you also review the ODB++ data when you do the output? That should show you that the component orientation is correct.

Thanks for the reply. I too never encountered before. Yes, I do review the ODB++ file with its free viewer and there it shows correctly as displayed in PCB or Artwork file. Even the Placed Component report also shows the correct location. I'm confused.

I would recommend asking the assembly house to verify that CAD CAM Professional is reading the ODB++ data correctly,

I just verified that the components on the bottom layer are written to the <jobname>/steps/stp/layers/comp_++bot/components file...
