Low cost programmable modular system to perform In-Circuit Test (ICT) full development of the hardware, software and mechanics of an ICT machine

Abstract

An In-Circuit Test machine (ICT) is a tool to carry out electrical tests on already assembled printed circuits through a set of probes making contact on some selected circuit nodes to monitorize their electrical signals or to induce electrical states at those nodes. This paper introduces the hardware, software and mechanical development of a low cost modular test system to make In-Circuit Test (ICT) intended for electronic prototypes of small and medium manufacturing series.
