The latest in SMT automated optical inspection systems

Monday, November 24, 2014: Automated optical inspection (AOI) systems are powerful tools for process control and verification during the various stages of the assembly process. They are designed to quickly identify visible defects on PCBAs including missing, misaligned and incorrect components. Recent advances in optics, lighting and image processing have made AOI systems an excellent choice for assemblies with complex inspection requirements. AOI plays a key role in the overall test strategy to ensure the highest possible quality, and complements the other test solutions. While electrical tests such as ICT or FCT verify electrical parameters, AOI verifies key aspects such as misplaced components or incorrect sizes that cannot readily be identified through electrical testing.

Model: VT-S720, Brand: Omron, Manufacturer: Omron Corporation, Japan

omronLaunched in January 2014, Omron’s VT-S720 is a 3D automated optical inspection machine with multiple cameras for a detailed inspection of PCBA related defects. It greatly reduces inspection costs that have plagued AOI for some time. Moreover, the machine bolsters defect prevention. The end result is an industry first approach to helping users to slash failure costs and optimise their investments in quality. The VT S720 uses new image processing technology to automatically sample fillet topological features.

Key features

  • 3D inspection system

  • Advertisement

    One top camera, four angled cameras

  • Patented true colour imaging processing

  • RGB colour lighting

  • Parameters have been optimally set to pick up gradations unperceived by humans and automatically separate good from bad products

  • Constant monitoring of production makes it possible to spot inspection troubles instantly, giving users a system optimised for improving productivity and quality
