X-ray instruments help to comply with RoHS

"X-ray instruments automate analysis procedures, are fully enclosed, and can be operated with basic skill levels in the factory with minimal safety requirements. The detection limit of lead, mercury and bromine is below 10 ppm, for cadmium and chromium below 20 ppm. As the instruments use a range of collimators, very small specimens, or areas on specimens, can be measured and analysed, using a video camera for precise positioning. This allows, for example, the analysis of lead and cadmium in narrow PCB tracks and the smallest soldering pads." Source: manufacturingtalk.com
