I have a method that balances the two (PCB vs schematic), in a way... I assign each
page of the schematic a range of numbers and annotate within that, e.g., page 1 is
100-199, 2 is 200-299 and so forth. Since the parts for a given page are USUALLY
physically close together, and don't cover a huge amount of board space, it's usually
fairly easy to find a specific designator.
A couple drawbacks:
- you're automatically stuck with 4- & 5-character designators;
- those few parts that 'wander' far from their schematic group can still be hard to
find!
Since we contract out the assembly, I don't hear the gripes of the assemblers -- for
better or for worse.

Hi Brad,
While I don't completely disagree with you. I have more sympathy for the
poor techs troubleshooting a pcb than the ring-wraiths seating in
developement meetings.
When looking for a part on a pcb, its far more practical to have the pcb
annotation in order. Schematic sheets are usually drawn in modules, so if
you know C23 is in the feedback of a high pass filter, you might try looking
on the filter schematic sheet. Of course, this is just my humble opinion.
Ring-wraiths - (Canadian term) - Engineers in Canada wear iron rings on
their working hands. It's symbolic and it matches the lobotomy scars!
