METHOD AND DEVICE FOR DETECTING A FAILURE OF ELECTRONIC UNITS IN PRINTED CIRCUIT BOARD ASSEMBLIES

摘要

The present invention relates to a method for detecting failures of electronic units (3) in a printed circuit board assembly (1), comprising the following steps of: consecutively activating the electronic units (3) according to a power-up sequence,wherein in each activating step one or more of the electronic units (3) are activated; after each step of activating one or more of the electronic units (3), obtaining an indication of an electrical parameter change with respect to a state before activating the one or more electronic units (3) and comparing the indication of the electrical parameter change with a provided reference parameter change associated to the one or more electrical units (3); and signaling a failure depending on the result of each comparing step.
