Production Run List - Slug 158 - IHWP IN - Flip-LEFT - Production

Slug started at approx 21:30 on March 7

• Good - Run 6991
  • Current steps up from 120 uA to 130 uA to 140 UA during run
  • BCM worries: Looks good. Pretty trippy, so BCM DD mean value jumps around. Concern is from digitals BCM DD disagreeing with analogs (and being a 2 sigma outlier) > So the digitals probably need to be checked on for this run. Specifically BCM DG US disagrees the most w.r.t. the rest of them and it has 5 extra ppm of noise for some reason
