Robustness Validation – EEModules + Systems

For the ZVEI, electric vehicles are a key to the climate- and environmentally-compatible mobility of the future. Reliable and constant general conditions in particular are essential to make Germany the lead supplier in this field.

For electrical/electronic modules (EEMs) the Robustness Validation approach allows significant improvements regarding quality, cost, and time-to-market.

Robustness Validation EEModules (2nd edition)

Whereas the first Handbook is about the validation of semiconductors and electronic components in general, the second Handbook is concerning about Robustness validation of stand-alone Electronic Control Units. 

More than 140 pages documented the practical application, methods of extrinsic reliability detection and prevention of Failures. This Robustness Validation Handbook provides the automotive electrical/electronics community with a common qualification methodology to demonstrate robustness levels necessary to achieve a desired reliability according a Zero Defect Strategy. 

Although this document primarily deals with electrical/electronic modules (EEMs), it can easily be adapted for use on mechatronics, sensors, actuators and switches. 

Knowledge Base EEM / ECU 

In order to apply and interpret the results of the Robustness Validation process, knowledge of the basic failure mechanisms of the electrical/electronic module is required. 

The EEM Knowledge Matrix lists known systematic failures mechanisms, i.e., failures that are systemic or inherent in the product by design or technology. It is a collection of the lessons learned by the organization using the Robustness Validation process. 

Component Process Interaction Matrix

The understanding of how a manufacturing process can reduce or affect the robustness of a product related to the mission profile is essential for its’ intended use. The Component Process Interaction Matrix is a tool which allows the evaluation of critical attribute interactions, the CPI – Matrix. 

Robustness Validation System Level 

This publication (as an Appendix to RV Handbook for EEM) focuses to the validation of robustness of a group of two or more interacting Electronic Control Units respectively Electrical/Electronic Modules.
