Symbols and units
a
Units entering (units)
b
Units passing without rework (units)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Counts first-pass units, not defects or eventual yield after rework. Supported limits: 0<=passing<=entering; integer counts.
