General discussion

Bonjour,

Je ne comprends pas pourquoi lorsque les paramètres "Chimique" sont remplis dans le profil de vie (colonnes P à S du premier onglet de l'outil ExperTool), le résultat après simulation ne fait pas apparaître de donnée dans la partie Stress Chimique.

Quand je modifie les données "Chimique", le taux de défaillance n'est pas modiéfié au final.

Merci d'avance

Hello everyone,

As for FIDES, is parts count method applicable for HF (microwave) / RF (radiofrequency) components?

In the section of "Parts-count reliability prediction" of FIDES Guide 2022, parameters for HF/RF components are not shown.

Is FIT the measure unit of lambda_physical?

In the standard I found the following:

For information, the link to the APSYS Training, on FIDES use, is broken. Is there training material elsewhere on how to complete the excel FIDES file?

I can see that the maximun number of records covered by the template is 1000. Is there a way to increase this number, or do I need to run a second template, to include all the components (1400 ish) and then add the failure rates?

Bonjour,

J'aurais 2 questions concernant la mise à jour de FIDES 2022 (Juillet 2023) Edition A.

• Ma première question concerne le "lambda_0Constructeur" appliqué aux condensateurs céramiques.

J'aimerais savoir pourquoi ce facteur n'a pas évolué depuis FIDES 2009, il en va de même pour les autres types ? 
(Dans le sens où ce facteur multiplicateur soit moins important).

Dear all,

our customer requests to use the FIDES tool to be used for evaluation of the failure rate and further integration in FMEDA.

However, during some part of its life, the part will be submitted to temperatures up to 150ºC.

In the FIDES, there is  a clear indication that the "The reliability prediction is applicable only in the range for which the component is qualified. The theoretical temperature range for which the FIDES Guide is applicable is: -55°C ≤ Tambient ≤ +125°C."
