The ABXY-ZT4 Series is a 6-DOF hybrid air-bearing and mechanical motion platform engineered for the rigorous demands of back-end exposure, wafer inspection, dicing, and annealing.
·X/Y axes use air bearings for smooth, frictionless motion
·T-Axis: micro-rotational adjustment for leveling
·Dual-drive stepper-driven axes with passive damping modules
·Z-Axis: fast, precise focus motion
