parts-units with the start-up circuit broken or disconnected-AND make sure they
fail the test. Then leave the test in the flow. Don’t drop the test just because nobody
has ever seen a part fail. Dropping that test would be courting disaster. Here at
National Semiconductor, we’ve appointed a Czar of Start-up Circuits. He is the
repository of all knowledge about circuits that do (and don’t) start properly. Since
this shy fellow (I shan’t give his name) began to reign, the goof-up rate has been cut
by many decibels.
