Accelerated Life Test

13 Test, Reliability, Yield & Failure Analysis

Notation ALT

Definition

A reliability test in which components are operated under elevated stress so failures occur sooner, allowing models to project lifetime or failure behavior at normal use conditions.

Application

Used for semiconductor qualification and reliability modeling with stresses such as temperature, voltage, current or humidity, while avoiding stress levels that introduce unrealistic failure mechanisms.
