In many industrial inspection applications, the high speed analysis of greyscale images is required. ICOS has developed vision systems, which can be, because of their programmability, used in a wide variety of vision applications. Four examples of applications in the electronics industry are presented and the main features of each application are described. The first application deals with the inspection of reed switches. The second and the third application are an inspection and alignment task in the assembly of PCBoards. The last application is a combined alignment and inspection task in the semiconductor industry. These present a sample of industrial applications solved with ICOS vision systems.
