Scope

GB/T 7289-2017 is the English-translated version of 电学元器件可靠性失效率的基准条件和失效率转换的应力模型.

GB/T 7289-2017 is the Chinese standard "Electric components -- Reliability -- Reference conditions for failure rates and stress models for conversion". Its scope clause reads: 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.

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.
