ABSTRACT
This chapter discusses the Development Phase through the application of reliability Design Maturity Testing (DMT) for Integrated Circuits, hybrids, and assemblies to ensure high reliability and long-life applications. DMT should be based on statistically driven sampling plans, primarily for environmental testing, to ensure that products are robust against life hazard conditions that could cause catastrophic field failures. The chapter describes DMT methods as well as the associated models for accelerated testing, statistical confidence, and reliability success-and-failure probability confidence bounds. DMT demonstrates a certain level of product reliability to help verify a product’s failure rate. The development of proper DMT planning requires a unique understanding of the technology platform. DMT documents should call for a capability test before and after accelerated life testing. To make DMT planning feasible and maintain consistent test methods on all products, it is advisable to use automated test planning software.
