Fundamentals of Reliability Testing: ALT, HASS, and ESS
This course provides a comprehensive introduction to the fundamental principles and practical applications of reliability engineering. Participants will gain a deep understanding of how to define and quantify product life and reliability, differentiate between failure mechanisms and failure modes, and establish accurate operational profiles.The curriculum delves into the calculation of product reliability and explores various types of reliability tests, with a strong focus on Accelerated Life Testing (ALT) and Highly Accelerated Life Testing (HALT). The course will also cover the critical role of environmental stress screening (ESS) in production control, demonstrating how reliability engineering principles can be leveraged to design robust quality controls, minimize defects, and enhance overall product quality.
