SFT080D Vibration Damping
SFT060D Vibration Damping
SFT040D Vibration Damping
Introduction:
The SFT series of shock-resistant active vibration isolators use pneumatic isolators as the main support in the vertical direction. In the horizontal direction, they employ a mechanical inverted pendulum negative stiffness mechanism in parallel with a positive stifiness mechanism. Combined with active vibration control and precise positioning control in both the vertical and horizontal directions, the system achieves high-performance active vibration isolation and stabilization across six degrees of freedom. This design meets the high-performance vibration isolation and shock resistance stability requirements for a wide range of equipment used in back-end packaging, semiconductor inspection and metrology applications.
Features:
● Pneumatic Air Sping as Main Support
● Active Vibration Control and Precision Positioning Control
● High-Performance Vibration lsolation and Impact Resistance
● Mechanical Inverted Pendulum Negative Stiffness Mechanism in Parallel with Positive Stiffness
● Meets High-Performance Vibration lsolation and Shock Resistance Stability Requirements
● Application Fields: Back-End Packaging. Semiconductor inspection, Metrology, Etc
