            •  Usually, there are two ways to monitor reliability during the manufacturing process.

                 a. Early Life Test

                     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. Units are monitored and tested on daily basis. Failed units will be analyzed and corrective                                 actions taken where necessary.
