Q6. How do we carry out quality control?
Usually, there are two ways to monitor reliability during the manufacturing process. Early Life Test This is used as a means of process control to identify any latent manufacturing problems and determine the effectiveness of burn-in. Every day, 5 samples will be picked up randomly from one of the production lines for burn-in at 50C+/-5C for 24 hours. On-going Reliability Demonstration This is a longer-term program aimed at providing data that continues to demonstrate the reliability of the product. 10 units per month are randomly collected from one of the production lines for burn-in for 168 hours at 50C+/-5C. Units are monitored and tested on daily basis. Failed units will be analyzed and corrective actions are taken where necessary.
