MIL-PRF-19500/620J
4.3.1 Screening (JANHC or JANKC). Screening of die shall be in accordance with MIL-PRF-19500. As a
minimum, die shall be 100-percent probed in accordance with table I, subgroup 2, except for thermal impedance.
4.3.1.1 JAN testing. JAN level product will have temperature cycling and thermal impedance testing performed in
accordance with MIL-PRF-19500, JANTX level screening level requirements. Electrical testing shall be in
accordance with table I, subgroup 2 herein.
4.3.2 Burn-in conditions. Burn-in conditions are as follows: IF = 3.0 A dc (min). Mounting and test conditions shall
be in accordance with method 1038 of MIL-STD-750, test condition B.
4.3.3 Thermal impedance measurements. The thermal impedance measurements shall be performed in
accordance with method 3101 or 4081 of MIL-STD-750, as applicable, using the guidelines in that method for
determining IH and IM. The thermal impedance limit (ZθJX) shall be less than the process determined statistical
maximum limit as outlined in method 3101 or 4081 of MIL-STD-750, as applicable. See group E, subgroup 4 of table
II herein.
4.4 Conformance inspection. Conformance inspection shall be in accordance with MIL-PRF-19500 and as
specified herein.
4.4.1 Group A inspection. Group A inspection shall be conducted in accordance with table E-V of
MIL-PRF-19500, and table I herein. The following test conditions shall be used for ZθJX, group A inspection:
a. IM measurement current:
1 mA to 10 mA.
b. IH forward heating current:
3A.
c. tH heating time:
10 ms.
d. tMD measurement delay time: 70 µs maximum.
4.4.2 Group B inspection. Group B inspection shall be conducted in accordance with the conditions specified for
subgroup testing in tables E-VIa and E-VIb (JANS, JANTXV, JANTX, and JAN) of MIL-PRF-19500 and as follows.
Electrical measurements (end-points) shall be in accordance with table I, subgroup 2 herein.
