Subject: Connector Reliability
Message:
We are using high-quality connectors (e.g. Cannon, AMP) in a military application. All connectors are PCB mounted. Using MIL-HDBK-217F we predict relatively high failure rates, in fact over 50% ofa module's failure rate.
My questions: Does anybody have any information regarding the applicability of the MIL-HDBK predicted rates for PCB connectors? Does anybody have other sources of PCB-connector reliability? Does anybody have a justifiable scaling factor for the MIL-HDBK rates? Or, are the MIL-HDBK rates realistic for these connectors?
We need a quantitative rate for the connectors for use in the FMECA.
Thanks, Andy Holton
