METHOD OF NONDESTRUCTIVE CHECK, DIAGNOSTICS AND REPAIR OF RADIO ELECTRONIC EQUIPMENT Russian patent published in 2011 - IPC G05B23/02 

FIELD: electricity.

SUBSTANCE: in method based on qualification of operable or faulty condition of controlled sample of radio electronic equipment (REE) depending on match or mismatch of measured values of parametres of electric signals of response and reference values of parametres of the same signals for operable condition of this type of REE, additionally infrared image (thermal image) of REE is produced with the help of digital video camera of infrared range with display of temperature conditions of electric radio elements (ERE) on it, as well as sections of electric circuits, and also their location in composition of REE sample, having detected REE faults by mismatch of measured and reference values of parametres of electric signals of response, produced infrared image of REE reflecting actual condition of ERE is compared with previously produced one, and results of comparison are used to determine location of faulty ERE to be replaced.

EFFECT: invention provides for detection of faulty electric radio elements without damage to integrity of moistureproof coating of printed circuit boards, increased efficiency and validity of REE faults diagnostics.
