RADC-TR-78-15, FINAL TECHNICAL REPORT: CRIMP CONNECTION RELIABILITY (JAN-1978)

RADC-TR-78-15, FINAL TECHNICAL REPORT: CRIMP CONNECTION RELIABILITY (JAN-1978)., This effort supports RADC TPO R-5-B, Solid State Device Reliability. Appendix A of the report, which includes a prediction model and updated crimp connection base failure rates, will be included in the next revision of MIL-HDBK-217B, Reliability Prediction of Electronic Equipment.\" Use of this revised and updated model and updated base failure rates will greatly improve the accuracy of crimp connection reliability predictions. The model developed consists of a base failure rate modified by multiplicative factors for environment, type of crimping tool, and quality procedures. The failure rate calculated from the model for a crimp termination in a fixed ground environment is approximately one order of magnitude less than the value of 0.0073 failures/10^ hours presently given in MIL-HDBK-217B.
