Electrical components reliability failure rate of the benchmark
Stress model of conversion of condition and failure rate
1 Scope
This standard specifies how to use the failure rate data for the reliability of electronic components in electronic equipment is expected.
The reference condition is a typical value of component stress observed in a large number of applications. The base condition is useful because it passes
The stress model considering real working conditions is used to calculate the failure rate under any conditions. In the early design stage, failure under the baseline conditions
The rate allowed for the actual reliability is estimated.
The stress model described in this standard is a general-purpose model that can be used to convert failure rate data to true working conditions when needed
Under the failure rate of the basis, which simplifies the estimation method, the conversion of failure rate data only allows the use of functional components within the specified limits
get on.
This standard also provides guidance on how to construct a component failure rate database to provide a failure rate that can be used in this standard stress model.
The baseline condition for specifying failure rate data is to allow data from different sources to be compared on the same basis. If the failure rate data according to
According to this standard is given, you do not need to attach specific conditions of the information.
This standard does not provide the basic failure rate of components, but to provide models to obtain failure rates obtained by other means by a working condition
Conversion to another working condition of the failure rate.
The methods described in this standard assume that components are used during their useful life. The standard method has versatility, but clear appropriate
For the component types given in Chapter 6 and Appendix E.2.
