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 total dose radiation level from a cobalt 60 source and 168 hr, 100? 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. omnirel? radiation test procedure note: sample die from each wafer were tested at each krad increment shown above. standard class level screening mil-prf-38535 screen level b* level s* test method required test method required wafer lot acceptance ----- ----- 5007 100% non-destructive bond pull ----- ----- ----- ----- pre-cap visual inspection 2010 100% 2010 100% temperature cycle 1010 100% 1010 100% constant acceleration 2001 100% 2001 100% visual inspection ----- 100% ----- 100% pind test ----- ----- 2020 100% serialization ----- ----- ----- 100% pre-burn-in electrical data sheet 100% data sheet 100% burn-in 1015/160 hrs. 100% 1015/240hrs. 100% interim electrical ----- ----- data sheet 100% pda calculations 5% functional lot 5% functional lot final electrical data sheet 100% data sheet 100% fine & gross seal 1014 100% 1014 100% radiographic ----- ----- 2012/two views 100% ** conformance inspection gr a 100% gr a 100% final visual inspection 2009 sample 2009 sample available product screening omr1033sr, omr1033st, OMR1033NM * for ? level screening add ? to part number, for ? level screening add ? to part number, see part number designator. ** additional conformance inspection testing, i.e. group b, c, & d optional.
