•

Radiation Testing is performed on a single wafer by wafer basis.

•

Each wafer is identified and a random sample of 5 die per wafer is selected.

•

The die are then individually assembled in a hermetic package, data logged, electrically

tested, hi-rel screened and then submitted to radiation testing.

•

The packaged die are submitted to Steady State Total Dose radiation per Method 1019,

Condition A, at a dose rate of 50 RAD/sec biased at maximum supply voltage.

•

Final electrical test is performed within two hours of both Total Dose Radiation level from

a Cobalt 60 source and 168 hr, 100°C annealing process. Read and record data

including two non-radiated control samples.

•

The wafer is then qualified only if samples from wafers meet full electrical specifications

after 150% of total dose rating as specified in each product data sheet.

•

Omnirel’s controlling specifications are as follows: For Voltage Regulators the

controlling specification is MIL-PRF- 38534/MIL-STD-883. For Rectifiers/Schottky the

controlling specification is MIL-PRF-19500/MIL-STD-750.
