3-D SCANNING SENSOR
Sep 1998PPT VISIONRequest Info
PPT Vision has introduced SpeedScan 3D, a high-speed, high-accuracy three-dimensional scanning sensor for OEM applications based on the company's Scanning Moire Interferometry (SMI) 3-D technology. Capable of coplanarity inspection on-the-fly at about 200 ms per component, SpeedScan 3D has an inspection accuracy of 2.5 µm. As a component moves past the SMI 3-D sensors, its entire surface is scanned and the 3-D topography is calculated in real time. The sensor can calculate both ball/lead and substrate coplanarity. SpeedScan 3-D is a compact, rigid sensor that scans a 2.25-in.-wide band at 5 in./s and can be integrated into most component-handling systems.
