MIL-PRF-38535K
APPENDIX A
A.4.5.8 Nonconformance. Lots that fail subgroup requirements of groups B, C, and D (and E if applicable) may be
resubmitted in accordance with the provisions of A.4.3.3.1. A failed lot that is reworked (see A.3.7.1) or is rescreened
(resubmittal to inadvertently missed process steps is not considered a rescreen) may not be resubmitted to the failed
subgroups (and shall be counted as a failure) for periodic group B, C, or D (or E if applicable) quality conformance
inspection (QCI) coverage. The lot may be resubmitted only to the failed subgroup to determine its own acceptance.
If a lot is not resubmitted or fails the resubmission, the lot shall not be shipped, and all references to MIL-PRF-38535,
or this appendix, shall be removed. For RHA microcircuits where group E tests are performed, and a sample plan of
18(1) and 38(1) is utilized for two successive lots of the same device type or for more than 10 percent of the lots
during the preceding 18 months, data as specified herein shall be provided. Resubmission for RHA qualification
inspection, in this case, may be required. Lots that are not resubmitted, fail the resubmission, are withdrawn from
compliance consideration, reworked, or rescreened (excluding resubmittal to final electricals when test conditions or
limits are not changed) due to the failure of a PDA or QCI requirement of this appendix shall be recorded and
properly dispositioned. The reporting of these lots shall include the following, as applicable:
a. PIN.
b. Inspection lot identification code.
c. Quantity of lot.
d. Point of scrap in manufacturer's flow.
e. Test results and date of failure (including all rescreening, reworks, and resubmissions).
f. Reason for failure or scrapping including applicable test results.
g. Date of scrapping or withdrawal from military consideration.
h. Disposition action of affected lots.
NOTE: The Government reserves the right to request and receive information concerning implementation of
corrective actions and justification for rework and rescreening.
A.4.5.8.1 Group B failure. When a lot failure occurs for a group B subgroup, then all other sublots within the
inspection lots shall be submitted to the failed subgroup.
A.4.5.8.2 Alternate group B failure. When a failure has occurred in group B using the alternate group B procedure,
samples from three additional inspection lots of the same package type, lead finish and week of seal as the failed
package shall be tested to the failed subgroups. If all three inspection lots pass, then all devices manufactured on
the same assembly line using the same package type and lead finish and sealed in the same week may be accepted
for group B inspection. If one or more of the three additional inspection lots fails, then no inspection lot containing
devices manufactured on the same assembly line using the same package type and lead finish sealed in the same
week shall be accepted for group B inspection until each inspection lot has been subjected to and passed the failed
subgroups.
