Fault diagnosis device of an electronic circuit and a fault diagnosis method

摘要

according to the invention, (a) the line circuit (100) of a circuit in the voltage or a voltage in order to supply (a), (b) the energy beam and the fluid jet generator (4, 10), (c) energy beam or fluid jet, and to investigate the change of temperature. uc2dcucf1c wiring of electric resistance changing the devices (5, 11), (d) distribution of the flow of current to the detection of the detector (3 3a) and (e) in the circuit is broken, the current and the current distribution of the fault, to decide whether the comparator (7, 7a, 7b, 7c, 7d) include the electronic circuit (100) can be used in order to provide a fault diagnosis device. according to the invention, the line circuit of the circuit in the current trend can be measured, and the structure of the circuit fault diagnosis approach is not able to.
