A Physics-of-Failure Approach for Accelerated Product Qualification and Quality Assurance

Overview:
Are you spending too much time and money in accelerated testing to improve the integrity of your products? Does your testing give you quantitative information about in-service reliability? Does your test program provide information for designers and manufacturers to proactively build-in reliability and quality into future products?
The physics-of-failure (PoF) approach provides a verifiable way to accelerate product maturity cost-effectively, and tailored accelerated stress testing is one of the key resources in the PoF approach. Accelerated stress exposures can be used to simulate compressed life-cycles, to evaluate potential failure mechanisms. If done early in the development phase, in conjunction with PoF design, stress tests can accelerate process and design maturity, and enable early introduction of products with robust stress margins. Accelerated stress exposures are also useful as a stress screen in the production phase, to stimulate and precipitate latent defects that could cause infant mortality in the field. Proper PoF-based use of accelerated
stress tests results in cost savings, time savings and quality
improvements, which are orders of magnitude better than those attained using traditional empirical approaches.
Learn the latest techniques for making accelerated stress testing a value-added activity. Hear how industry leaders are using accelerated test results to take pro-active corrective action early in the design and production phases for ensuring consistently high integrity of design and process. See the latest web-based tools to facilitate the job of integrating PoF approaches into the product qualification and quality assurance process.
