MIL-PRF-19500/558J
4.4 Conformance inspection. Conformance inspection shall be in accordance with MIL-PRF-19500 and as
specified herein. If alternate screening is being performed in accordance with MIL-PRF-19500, a sample of screened
devices shall be submitted to and pass the requirements of table I, group A1 and group A2 inspection only (table E-
VIb, group B, subgroup 1 is not required to be performed again if group B has already been satisfied in accordance
with 4.4.2 herein).
4.4.1 Group A inspection. Group A inspection shall be conducted in accordance with MIL-PRF-19500 and table I
herein.
4.4.2 Group B inspection. Group B inspection shall be conducted in accordance with the conditions specified for
subgroup testing in table E-VIa (JANS) of MIL-PRF-19500 and 4.4.2.1 herein. Electrical measurements (end-points)
and delta requirements shall be in accordance with table I, subgroup 2 and 4.5.5 herein, delta parameters apply to
subgroups B4 and B5. See 4.4.2.2 for JAN, JANTX, and JANTXV group B testing. Electrical measurements (end-
points) and delta requirements for JAN, JANTX, and JANTXV shall be after each step in 4.4.2.2 and shall be in
accordance with table I, subgroup 2 and 4.5.5 herein.
4.4.2.1 Group B inspection, table E-VIa (JANS) of MIL-PRF-19500.

VCB = 10 V dc, PD ≥ 100 percent of max rated PT (see 1.3). (NOTE: If a failure
B5

occurs, resubmission shall be at the test conditions of the original sample.)
Option 1: 96 hours minimum sample size in accordance with MIL-PRF-19500,
table E-Via, adjust TA or PD to achieve TJ = +275°C minimum.
Option 2: 216 hours minimum, sample size = 45, c = 0; adjust TA or PD to
achieve TJ = +225°C minimum.
4.4.2.2 Group B inspection, (JAN, JANTX, and JANTXV). Separate samples may be used for each step. In the
event of a lot failure, the resubmission requirements of MIL-PRF-19500 shall apply. In addition, all catastrophic
failures during CI shall be analyzed to the extent possible to identify root cause and corrective action. Whenever a
failure is identified as wafer lot and wafer processing related, the entire wafer lot and related devices assembled from
the wafer lot shall be rejected unless an appropriate determined corrective action to eliminate the failure mode has
been implemented and the devices from the wafer lot are screened to eliminate the failure mode.
