‣ What are the three performance classes? ✓✓1-General Electronics 2-
Dedicated Service 3-High reliability
‣ Who is the end user? ✓✓The end user is the individual or agency that
contracts the printed board or assembly to be designed and manufactured
‣ Who determines the class of a product? ✓✓The end user
‣ What would be in class 3 performance? ✓✓Military, medical, etc.
