Ioan,
See IPC-9261.
It's not real clear which category of opportunity polarity falls into, but I would include it as a placement defect.
Placement opportunities are separate from termination opportunities, and there's one placement opportunity per component whether or not the component has a polarity.

Dear Technos,
For DPMO purposes, how do you define polarized components? And I mean beyond diodes, tantalum caps and ICs, for instance connectors or DPAKs. Hypothetically one can mount a DPAK at 90, 180 or 270 degrees. It is obvious, easy to see if this part, or an RJ connector is mounted in a different position than required, but are they considered polarized parts when doing the opportunities count?
Thanks,
Ioan Tempea, ing.
