This is used as a mean of process control aimed at identifying any latent manufacturing problems and determining the effectiveness of burn-in. Every day, 5 samples will be picked up randomly from one of the production lines for burn in at 50°C+/-5°C for 24 hours.

b. On-going Reliability Demonstration

This is a longer-term program aimed at providing data on continuous basis to demonstrate the reliability of product. 10 units per month are randomly collected from one of the production lines for burn-in for 168 hours at 50°C+/-5°C.
