METHOD OF DIAGNOSTICS OF RADIO ELECTRONIC DEVICES Russian patent published in 2019 - IPC G01R31/26 

FIELD: physics.

SUBSTANCE: invention relates to technical diagnostics and can be used for automated contactless diagnostics of the technical state of radio electronic devices (REU) of various types. Method for diagnosing radio electronic devices includes placing a technically sound multilayer printed circuit board in a fixed position in an alternating rotating electromagnetic field of strictly defined intensity, in such a way that the vector of the electromagnetic field intensity affects all elements of the printed circuit board from different directions and induces an electromotive force in them, measurement of the EMF indices from the outputs of the multilayer printed circuit board and taking them as reference ones; introduction of a subsequent printed circuit board in the same fixed position in the alternating rotating electromagnetic field of the same intensity, measurement of EMF indicators from the outputs of the multilayer printed circuit board and their comparison with reference indicators stored in the data bank, and if there are differences between real and "reference" indicators exceeding the permissible, the parameters of the mismatch are sent to a computer to make a decision on the further operation of the multilayer printed circuit board.

EFFECT: technical result is higher reliability of selection of diagnosed radio engineering devices.
