Test methods are referenced to MIL-STD-883 as determined by MIL-PRF-38534.
notes:
1. Redmond site, Interpoint brand, has a DSCC approved Radiation Hardness
Assurance plan. Our SMD products with RHA “P” or “R” code met DSCC
requirements.
2. Space Prototypes are non-QML products and may not meet all of the
requirements of MIL-PRF-38534. “O” in the RHA designator position in Interpoint
model numbers indicates DSCC RHA “-” defined as no RHA.
3. All processes are QML qualified and performed by certified operators.
4. not required by DSCC but performed to assure product quality.
5. Burn-in temperature designed to bring the case temperature to +125°C minimum.
6. Includes low dose rate to the rated total dose (TID)
7. no upset at the pins.
