4.4.4.3 Dose rate upset testing. Dose rate upset testing shall be performed in accordance with test method 1021 of
MIL-STD-883 and herein (see 1.5).
a. Transient dose rate upset testing shall be performed at initial qualification and after any design or process changes
which may effect the RHA performance of the devices. Test 10 devices with 0 defects unless otherwise specified.
b. Transient dose rate upset testing for class Q and V devices shall be performed as specified by a TRB approved
radiation hardness assurance plan and MIL-PRF-38535.
4.4.4.4 Single event phenomena (SEP). When specified in the purchase order or contract, SEP testing shall be
required on class V devices (see 1.5 herein). SEP testing shall be performed on a technology process on the Standard
Evaluation Circuit (SEC) or alternate SEP test vehicle as approved by the qualifying activity at inital qualification and after
any design or process changes which may affect the upset or latchup characteristics. The recommended test conditions
for SEP are as follows:
a.The ion beam angle of incidence shall be between normal to the die surface and 60° to the normal, inclusive (i.e. 0°
< angle < 60°). No shadowing of the ion beam due to fixturing or package related effects is allowed.
b.The fluence shall be > 100 errors or > 106 ions/cm2.
c. The flux shall be between 102 and 105 ions/cm2/s. The cross-section shall be verified to be flux independent by
measuring the cross-section at two flux rates which differ by at least an order of magnitude.
d.The particle range shall be > 20 microns in silicon.
e.The test temperature shall be +25°C and the maximum rated operating temperature +10°C.
f. Bias conditions shall be defined by the manufacturer for latchup measurements.
g.Test four devices with zero failures.
4.5 Delta measurements for device class V. Delta measurements, as specified in table IIA, shall be made and recorded
before and after the required burn-in screens and steady-state life tests to determine delta compliance. The electrical
parameters to be measured, with associated delta limits are listed in table IIB. The device manufacturer may, at his
option, either perform delta measurements or within 24 hours after life test perform final electrical parameter tests,
subgroups 1, 7, 9.
5. PACKAGING
5.1 Packaging requirements. The requirements for packaging shall be in accordance with MIL-PRF-38535 for device
classes Q and V or MIL-PRF-38535, appendix A for device class M.
6. NOTES
6.1 Intended use. Microcircuits conforming to this drawing are intended for use for government microcircuit applications
(original equipment), design applications, and logistics purposes.
6.1.1 Replacability. Microcircuits covered by this drawing are intended for use for government microcircuit applications
(original equipment), design applications, and logistics purposes.
6.1.2 Substitutability. Device class Q devices will replace device class M devices.
6.2 Configuration control of SMD's. All proposed changes to existing SMD's will be coordinated with the users of record
for the individual documents. This coordination will be accomplished using DD Form 1692, Engineering Change Proposal.
