individual tests or groups of tests.
J.3.11.1 Group A electrical testing. Group A electrical testing shall be satisfied by in-line inspections performed in
accordance with the applicable procedure of MIL-STD-883 on actual devices.
J.3.11.2 Group C life tests. Life tests shall be performed on the SEC at intervals set by the TRB in the quality
management plan.
J.3.12 Test optimization requirements. The process used by the manufacturer to optimize testing utilizing the best
commercial practices available while still assuring all performance, quality and reliability requirements herein. All of
the applicable JEP121 process elements shall be addressed for test optimization. Any screen or TCI test prescribed
herein may be reduced, modified, moved, or eliminated by the QML manufacturer provided the following
considerations are addressed as a minimum.
a. Nodes critical to test outcome, called test critical nodes, have been identified and are in control in
accordance with TechAmerica EIA557.
b. Test critical nodes have exhibited sufficient capability to assure low product defect rates.
c. An understanding and control of assignable causes at test critical nodes.
d. The long term reliability of devices remains unaffected or is improved.
e. Low defect rates in the process and delivered product are maintained.
f.
Measurements taken for out of control conditions along with corrective actions are recorded and this data is
maintained for a time period consistent with data retention requirements herein.
g. Method and frequency for revalidation of optimized tests shall be defined in the manufacturer’s
documentation.
The manufacturer is expected to maintain the established process control and evaluate the effect on quality and
reliability of any out of control conditions that may exist at critical nodes. The manufacturer shall also evaluate if a
relationship exists between any optimized test and any field failure returns, take appropriate corrective actions, and
report this information as part of the TRB status reports. Regardless of testing modifications, the manufacturer shall
supply product capable of passing any screening or TCI/QCI test prescribed herein. As a part of the QML philosophy
and the conversion of customer requirements the manufacturer shall communicate variations in screening, end-of-line
testing with customers as appropriate. This information shall be available from the manufacturer and to the QA.
