NS221 — Basic Vacuum Systems II
NS 221 - Basic Vacuum Systems II NS 221 - Basic Vacuum Systems II Vacuum technology is the field whereby very low-pressure environments are created, maintained and analyzed, such as those needed in the fields of semiconductor manufacturing, glass coating and research. NS221 covers the pump-down performance of rough vacuum systems based on the process of positive displacement. System conductance and pump-down performance are affected by the selection of the specific vacuum hardware component types, such as pumps, pressure gauges, valves, and chambers. Course
