View Engineering Inc. (Simi Valley, CA), a designer and manufacturer of vision measurement systems, has announced the integration of linear motors into their View Summit series of large format, vision measurement/inspection systems. Linear motors are not subject to the same velocity and acceleration limitations inherent in systems converting rotary to linear motion, such as lead screw systems.
The integration of linear motors provides the platform with the higher velocities and accelerations needed to satisfy near-line measurement/inspection requirements. The systems operate precisely to 0.1 micron at velocities ranging from 400 to 500 mm/sec. The combination of precision and speed is critical in addressing the process monitoring and quality improvement needs of manufacturers challenged by higher manufacturing volumes, decreased design geometries and tighter tolerances.
The inspection system's design features include a fixed bridge design with a heavy-duty granite base and arch, passive vibration isolation system and non-contact stage encoders offering 0.1-micron resolution. Available in a variety of sizes, it can measure large footprint parts such as printed circuit boards (PCBs), stencils, flat panel displays, etching sheets and mask patterns, as well as nested groups of smaller parts.
