Xy Linear Motor Stages, Low-Profile

Aerotech has introduced a series of integrated open-frame Linear Motor Stages with precise geometric performance and micrometer-level straightness. The new PlanarDLA stages include high precision roller bearings, precision machined surfaces and non-contact linear motors that drive through the axes’ centre of stiffness. These features result in straightness to ±0.5µm and flatness to ±1.25µm. The low-profile stages are designed for a wide range of applications from highly dynamic two-sided LED wafer processing to quasi-static optical metrology. There are nine models in the series to accommodate customer requirements for travel and accuracy. The PlanarDLA enables high-throughput, high-accuracy processing with 2 m/s velocities and 2 g accelerations, resulting in superior process yield and a low total cost of ownership. It achieves high servo bandwidths while maximizing the clear aperture available and keeping the overall height to a minimum.
