Subject: Microcircuit Quality Factors for Custom Screening
MIL-HDBK-217F, Notice 2; Section 5.10 - Microcircuits Quality Factors Reference Page 5-16: In the Quality Factor calculation for Custom Screening Programs, MIL-STD-883 Tests for Group 1 & Group 2 are the same. However (1) Point Valuation for Group 1 is 50; (2) Point Valuation for Group 2 is 37 ????? How can both Groups having same tests have different Point Valuations and hence different Quality Factors ?????
