High Brightness LED (“HB-LED”) usage is increasing for new applications as manufacturing costs decrease and performance improves. Applications such as mobile phone LCD screens and keypads and flashlights for camera phones have been the drivers for market growth in the last couple of years, as well as car headlights, LCD TV backlights and traffic signaling. HB-LED’s typically are used for high-end applications, making quality control imperative. Our ICOS wafer inspector offers outgoing automated visual inspection of HB-LED wafers for quality of the wafer surface.
