Burn-in testing is a process used to identify early failures in electronic components or systems. During this testing, devices are operated under elevated temperatures and voltages for an extended period. This helps to stress the components, allowing any potential defects to manifest before the product is deployed. The goal of burn-in testing is to improve reliability and ensure that products meet quality standards. It is commonly applied in industries such as electronics, computers, and automotive manufacturing. By catching issues early, manufacturers can reduce the risk of product failures in the field, ultimately saving time and costs.
