(R) Handbook for Robustness Validation of Automotive Electrical/Electronic
Modules
Description / Abstract:
This document addresses robustness of electrical/electronic
modules for use in automotive applications. Where practical,
methods of extrinsic reliability detection and prevention will also
be addressed. This document primarily deals with
electrical/electronic modules (EEMs), but can easily be adapted for
use on mechatronics, sensors, actuators and switches. EEM
qualification is the main scope of this document. Other procedures
addressing random failures are specifically addressed in the CPI
(Component Process Interaction) section 10. This document is to be
used within the context of the Zero Defect concept for component
manufacturing and product use.
It is recommended that the robustness of semiconductor devices and other components used in the EEM be assured using SAE J1879 OCT2007, Handbook for Robustness Validation of Semiconductor Devices in Automotive Applications.
The emphasis of this document is on hardware and manufacturing failure mechanisms, however, other contemporary issues as shown in Figure 1 need to be addressed for a thorough Robustness Validation. A Pareto of contemporary issues is shown in Figure 1. Although this document addresses many of the issues shown, however some are outside the scope of this document and will need to be addressed for a thorough RV process application. Examples of issues outside the scope of this document are system interactions, interfaces, functionality, HMI (Human-Machine Interface) and software. At the time of publication of this handbook, a system level Robustness Validation handbook, which addresses these issues, had been initiated.
Purpose
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.
The Robustness Validation approach emphasizes knowledge based engineering analysis and testing a product to failure, or a predefined degradation level, without introducing invalid failure mechanisms. The approach focuses on the evaluation of the Robustness Margin between the outer limits of the customer specification and the actual performance of the component These practices integrate robustness design methods (e.g.,, test-to-failure in lieu of test-to-pass) into the automotive electronics design and development process. With successful implementation of robustness validation practices, the producer and consumer can realize the objectives of improved quality, cost, and time-to-market.
The purpose of this Robustness Validation Handbook is to establish globally accepted concepts, processes, methods, techniques and tools for implementing the Robustness Validation qualification methodology for automotive electrical/electronic modules (EEM) and systems.
