Editor note; although not mentioned, vibration is a major concern. All part reliability models include the effects of environmental stresses through the environmental factor π E (except for the effect of ionizing radiation). But many failure modes in the real world do not follow the equation. 1990. The 217 Plus prediction module incorporates the component failure rate prediction models developed by the RIAC (Reliability Information Analysis Center). As a consequence of the rapidly advancing and ever-changing technology base, in the brief span of less than 3 years, MIL-HDBK-217C was updated to MIL-HDBK-217D in 1982, which in turn was updated to MIL-HDBK-217E in 1986. If anyone has access to DoD Assist a search for MIL-HDBK-217 will take you to the active version where there is a link for the revision project. MIL-HDBK-217 provides two reliability prediction methods: The Parts Count Method. The tool simplifies the microcircuit portion of the MIL-HDBK-217 parts count method by defaulting the learning factor to 1.0 and not providing the quality factor calculations for custom part screening regimes, as both of these are rarely used in practice. The main physical contributors to failures in storage are not the same than in operation. Capacitor Style. MIL-HDBK-217 Environmental Conditions.
