APPENDIX A
A.3.4.1.2.6 Lead trimming and final lead finish thickness. The manufacturer shall monitor the package lead
lengths to assure meeting the applicable device specification or drawing for proper lead length and the final lead
finish thickness in accordance with this appendix. The frequency of the lead length monitor shall be performed at
each equipment setup as a minimum. A sample and test plan shall be available for review by the qualifying or
preparing activity.
A.3.4.1.3 Qualification to RHA levels. Qualification to a RHA level shall consist of characterization to the highest
offered RHA level of total ionizing dose (TID). The conditions for radiation testing shall consist of exposing the
devices in a step-stress manner to the highest dose level offered and as a minimum the two next consecutive lower
RHA levels. The levels are identified as follows: 3K Rad(Si), 10K Rad(Si), 30K Rad(Si), 50K Rad(Si), 100 K Rad(Si),
300K Rad(Si), 500K Rad(Si), 1M Rad(Si). The radiation testing plan (QM Plan) and qualification to the appropriate
quality and reliability assurance level for device classes B, Q, S, V, Y or T shall be submitted for QA approval. The
designator RHA levels are defined below:
