IMO, legally the callout 6012 + 6016 needs to be reconciled on your front end before you tender the quote, sorry Joey.

For what it is worth, every OEM we work with has transitioned to waiving 6016 callouts, or removing it from the drawings.  The big driver was wrap plating.

Also, I'm nearly 100% certain that 6012 + HDI (verbiage or features) does not imply a 6016 contract, even with the 6011 loop around.

Subject: [IPC-600-6012] 6012 & 6016

6012C section 1.2, item 3 implies that 6016 always applies to rigid boards containing HDI features.
We see designs with HDI features with mixed callouts: some 6012 only, others 6012 & 6016.
Are both callouts to be treated equally?? I believe so, but I'd like to see how others interpret the above.
