4.4.2 Group B inspection. Group B inspection shall be in accordance with table II of MIL-PRF-38535.
4.4.3 Group C inspection. Group C inspection shall be in accordance with table IV of MIL-PRF-38535 and as
a. End-point electrical parameters shall be as specified in table II herein. Delta limits shall apply only to
subgroup 1 of group C inspection and shall consist of tests specified in table IV herein.
b. The steady-state life test duration, test condition, and test temperature, or approved alternatives shall be
as specified in the device manufacturer's QM plan in accordance with MIL-PRF-38535. The burn-in test
circuit shall be maintained under document control by the device manufacturer's Technology Review
Board (TRB) in accordance with MIL-PRF-38535 and shall be made available to the acquiring or
preparing activity upon request. The test circuit shall specify the inputs, outputs, biases, and power
dissipation, as applicable, in accordance with the intent specified in test method 1005 of MIL-STD-883.
4.4.4 Group D inspection. Group D inspection shall be in accordance with table V of MIL-PRF-38535. End-point
electrical parameters shall be as specified in table II herein.
4.5 Methods of inspection. Methods of inspection shall be specified and as follows:
4.5.1 Voltage and current. Unless otherwise specified, all voltages given are referenced to the microcircuit GND
terminal. Currents given are conventional current and positive when flowing into the referenced terminal.
4.5.2 Burn-in and life test cool down procedures. When the burn-in and life tests are completed and prior to
removal of bias voltages, the devices under test (DUT) shall be cooled to within 10°C of their power stable condition
at room temperature; then, electrical parameter end-point measurements shall be performed.
TABLE IV. Delta limits at 25°C.
1/ The above parameters shall be recorded before and after the
required burn-in and life tests to determine deltas (Ć).
