Q4. How do we carry out quality control?
A: 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.
