The FIDES Guide is a global methodology for reliability engineering in electronics.

It contains two parts:

  • A reliability prediction guide,
  • A reliability process control and audit guide.

The FIDES Guide aims to enable a realistic assessment of the reliability of electronic equipment, including systems operating in severe environments (aeronautics, defense systems, industrial electronics, transport, etc.). The FIDES Guide also aims to provide a concrete tool to develop and control this reliability. Its key features are:

  • Providing models both for electrical, electronic, and electromechanical components, and for the PWAs or some subassemblies.
  • Revealing and taking into consideration all technological and physical factors that play an identified role in a product's reliability.
  • Taking into precise consideration the mission profile.
  • Taking into consideration the electrical, mechanical and thermal overstresses.
  • Taking into consideration the failures linked to the development, production, field operation and maintenance processes.
  • The possibility of distinguishing several suppliers of a same component.

By identifying the factors contributing to reliability, whether technological, physical or process-based, the FIDES Guide makes it possible to revise product definition and intervene throughout the product lifecycle, to improve and control reliability.

There are two versions : in french and in english.
