Qualification Testing
The 2mm cPCI family of connectors has been flight qualification tested per Mil-DTL-55302, EEE-INST – 002 (NASA
Goddard Space Flight Center Document), GEVS-SE, Rev. A, General Environmental Verification Standard for STS &
ELV Payloads, Subsystems and Components. Testing included, but was not limited to:
LLCR:
DWV:
CRD:
Low Level Contact Resistance
Dielectric Withstanding Voltage
Contact Resistance
IR:
MFG:
Insultation Resistance
Mixed Flowing Gas

Testing was performed to determine if fretting occurs due to mechancial motion and to evaluate the integrity of
the Hypertac contact system relative to severe shock. To validate the test, low nanosecond event detection was
perfromed at 10 nanoseconds.
There were no events recorded.
** Testing was performed using a 6U Flight Chassis to determine if fretting occurs due to mechanical motion and
to evaluate the integrity of the test samples relative to severe mechanical eniviroment.To validate the test, low
nanosecond event detection was performed at 50 nanoseconds.
There were no events recorded.

1. Differential S-parameter
1, 2
2. Propagation Delay and Skew
Propagation delay through the intrinsic connector assembly is estimated by making a measurement on the reflected
signal received on the same broadband fixture that is used to obtain the full vector scattering parameters. In these
measurements, there is no inclusion of any other pin lengths other than what is within the intrinsic connector.
