RJA only, as applicable (see 1.3) and in accordance with thermal impedance curves.

Not applicable.

4.4.3.3 Group C sample selection. Samples for subgroups in group C shall be chosen at random from any

inspection lot containing the intended package type and lead finish procured to the same specification which is

submitted to and passes table I tests herein for conformance inspection. When the final lead finish is solder or any

plating prone to oxidation at high temperature, the samples for C6 life test may be pulled prior to the application of

final lead finish. Testing of a subgroup using a single device type enclosed in the intended package type shall be

considered as complying with the requirements for that subgroup.

* 4.4.4 Group D inspection. Conformance inspection for hardness assured JANS, JANJ, and JANTXV types shall

include the group D tests specified in table II herein. These tests shall be performed as required in accordance with

MIL-PRF-19500 and method 1019 of MIL-STD-750, for total ionizing dose or method 1017 of MIL-STD-750 for

neutron fluence as applicable (see 6.2 herein), except group D, subgroup 2 may be performed separate from other

subgroups. Alternate package options may also be substituted for the testing provided there is no adverse effect to

the fluence profile.

4.4.5 Group E inspection. Group E inspection shall be conducted in accordance with the conditions specified for

subgroup testing in table E-IX of MIL-PRF-19500 and as specified in table III herein. Electrical measurements (end-

points) shall be in accordance with table I, subgroup 2 herein; delta measurements shall be in accordance with the

applicable steps of table IV.

4.5 Methods of inspection. Methods of inspection shall be as specified in the appropriate tables and as follows.

4.5.1 Pulse measurements. Conditions for pulse measurement shall be as specified in section 4 of

MIL-STD-750.
