Impact of burn-in testing on power supply reliability

Optimizing process control
The important point to note is that quality and reliability cannot be “tested in” or “inspected in.” Burn-in testing is ultimately another inspection process, but serves as a mechanism for process control and feedback. Failures in burn-in along with field failures prompt failure analysis and corrective action to ensure that the product design and process have been centered and optimized to provide the best product possible in the field. Studies have shown that higher factory yields give higher product reliability, happier customers and lower warranty-return costs.
