We experience multiple lots of NC4AD3243 low yield on FT HOT at VOL tests (10.04 – 10.06, R1,R2,R3_VOL).
Unfortunately, this is DOS test program so I could not retrieved the datalog from different mom lot to see the process variation.
The product is on the single pass hot test route. My team has collected HOT, ROOM, COLD datalog from 100 units, the VOL seems worst at HOT.
Can we extended the FT HOT max limit to 0.330V(EC Table max is 0.4V) base on 6sigma limit base? Kindly help review GBD characterization summary sheet and let us know your recommendation. Thank you.
