New Way Porous Media Precision Chucks are engineered for use under or near precision FPD glass manufacturing processes or Automated Optical Inspection (AOI) stations, inline or off-line. They provide a much higher level of precision, stiffness, and damping than traditional air conveyors. The vacuum holes are designed so that, with air pressure on, the flow through a vacuum hole is the same whether there is glass over it or not. Simple and smart. This also means that as the glass comes on and off the chuck, the vacuum pressures and air gaps remain the same.

These FPD precision chucks provide ±5µm control, well within the focal range of most optical inspection systems. This is a significant advantage over conventional contact bearings or orifice-based air bearings, especially for coating or AOI applications in Gen-10 or higher manufacturing lines. Superior stiffness provides for faster settling time and higher yield, without the scratching or breakage typical of competitive systems. And the larger the glass size, the bigger your advantage.

In addition to the standard porous media precision chuck(shown), custom fpd solutions are also available. Just contact the New Way Sales Department.
