Description

Technical Specification of Intermediate Frequency AC Magnetron Sputtering Power Supply, SST Series

SST series of intermediate frequency magnetron sputtering power supply work in two-stage high frequency conversion mode, AC sinusoidal output 40kHz. Intermediate sputtering power supply makes two sputtering targets as load, two targets work alternatively. Therefore, each sputtering target has inverse voltage over half of the time during the work cycle, enabling the stored charge on the target surface to discharge sufficiently, beneficial to restrain arc discharge of the target materials and surface poisoning.
