TL;DR: I like internal part numbering systems for passive chips and the like, and keeping MPNs for active components (or components with many variants and/or options that could be easily confused as equivalents). I've always been a fan of internal

charles, i can appreciate the hand held "reel to reel" scanner as a good solution that is very cost effective. during my smt supervision days we had a number of part loading checks. 1. load plan check, 2. scan check, 3. reel to reel manual check.

Don�t be afraid of the more standard doubles sided mixed process. Even without a chip wave it works, don�t get me wrong it works better with the chip wave, but even without chances are you will be spending more on the additional steps than you would
