|PPT VISION's new 3D sensor for OEM triples the speed of coplanarity inspection.|
|PPT VISION has announced SpeedScan 3D®, a high speed, high accuracy 3D scanning sensor for OEM applications based on the company's Scanning Moire Interferometry 3D (SMI® 3D) technology. This patented technology increases the speed and accuracy of coplanarity inspection by over 300% for BGA, QFP, CSP, TSOP and other bumped or leaded components. In OEM applications, SpeedScan 3D sensors are capable of coplanarity inspection on-the-fly at about 200 milliseconds per component, with inspection accuracy of 2.5 microns. This is many times faster and more accurate than currently available systems that are typically based on laser technology, vision triangulation techniques or some form of structured lighting.
SpeedScan 3D is a compact, rigid sensor that scans a 2.25 inch wide band at 5 inches per second and can easily be integrated into most component handling systems. "The large area of coverage, high scanning speed and exceptional accuracy make SpeedScan 3D particularly attractive to OEMs. Since components are inspected while in motion, throughput is maximized and mechanical complexity is minimized," says Joe Christenson, president of PPT VISION.
SMI 3D is based on the long established phase-shift Moire interferometry technology, with the added feature of scanning at a high speed. As a component is moved past the SMI 3D sensor, its entire surface is scanned and the 3D topography is calculated in real time. Both ball/lead and substrate coplanarity can be calculated by the new sensor.
PPT VISION is an industry leader in solving difficult inspection problems utilizing advanced machine vision techniques.
