This master thesis has been carried out in collaboration with SPEA, a worldwide electronic testing leader company. SPEA systems have several fields of application: automotive, MEMS and sensors, aerospace, communications and medical. As biomedical devices are essential for the patient's health, testing them becomes crucial for their proper functioning. Therefore, feasible testing procedures are necessary. Many manufacturers adopt SPEA systems to guarantee both product functionality and integrity. During this internship, I have focused on the general issue of testing an electronic board in order to develop its basic principles. SPEA testing is divided into three main phases: in circuit test (ICT), on board programming (OBP) and functional test (FCT).
