Ansaldo Breda is one of the world leading train manufacturing company that has had long term collaborations with the University of Naples Federico II in fields as diverse as metal processing, welding and brazing, advanced materials technology, metrology, nondestructive evaluation, material characterisation, etc. Ansaldo Breda recently submitted a technological enquiry regarding the establishment of appropriate metrology procedures for nondestructive characterization of micro features in insulated gate bipolar transistor(IGBT)assembly devices for the railways traction industry.

Assistance was given by the University of Naples Federico II to the Ansaldo Breda company about the general aspects concerning the metrological problems applied to the micro features of insulated gate bipolar transistor (IGBT) for for the railways traction industry. The development of advanced ultrasonic nondestructive evaluation procedures was proposed to achieve the client requirements. The collaboration could lead to a future paid RAS initiative based on a dedicated consultancy contract and project development.
