ABSTRACT The aim of this thesis was to design a new system interface to exploit the new automatic test equipment “T100” designed by Spea Spa, to program and test the washing machine control panel and its board into as a whole and verify its performance. It can also be seen as an improved design of flying probe tester, by adjusting the test head, fixture and other important parts to broaden its field of application. This thesis was offered by SPEA Spa, through the coordination of Fabrizio Carnisio and Piergiuseppe Ranieri, respectively customer manager and test engineer in Spea company. The project was commissioned by a European leader company in this field.
