Développement d’un Système de Diagnostic des Cartes Electroniques par Mesure d’Impéda (Flying prob ICT) nce

Abstract

Electronic card manufacturers are faced with the requirement of quality control and the shortening of their time to market. This requires an efficient and rapid quality control process, and therefore a well-adapted test strategy. In any manufacturing process, tests are normally carried out on the product, the tests are carried out in two phases, a first one consists of electrically testing all the components soldered on the PCB and a second phase in which the operation of the whole assembly is assessed. In this context, we have proposed a diagnostic system for electronic boards by impedance measurement (ICT). The realized system consists of a measurement circuit based on an Arduino Uno, this circuit connected to a user interface to display and detect the defective components. The device produced is capable of measuring a range of resistances ranging from 100Ὼ to 50kῺ .the results of the tests carried out on the system produced are conclusive and allow in perspective to improve the measuring device in order to be able to measure the impedances L, C.
