A hybrid integrated circuit comprises a combination of two or more integrated circuit types, or one integrated circuit type and discrete components. This section describes the failure rate model to be used for predicting the failure rate of a hybrid device under stated environmental and operating conditions. However, because the model involves both discrete components and integrated circuits, it is also necessary to refer to the tables in Appendix A for discrete electronic and electro-mechanical components and for microelectronic devices.

This section describes the failure rate model for a hybrid device and provides failure rates and factors for those characteristics that are peculiar to a hybrid device. Other failure rates and factors that are part of the total model are contained in the tables found in Discrete Electronic and Electro-mechanical Components1 and the tables found in Microelectronic Devices (Excluding Hybrids). An example is given of the application of the model.
