Annotation:  The general principles of a choice of information source types and character for the systems of non-destructive control of electronic modules based on the information theory are defined in the paper. It is established that combined system of optical and x-ray control allows to define the greatest number of defect types. The images of optical range have strictly predetermined number of defect types (up to 64%) and provide some priori information on defects which can be defined on x-ray images. It is offered to characterize the differences of the x-ray images from the image of an optical range by values of conditional entropy received at various operating modes of the equipment. Computing experiment has been made for the purpose of efficiency check of disparity measure using for detection of defects of electronic module. It is established that the accuracy of defect detection on x-ray images is from 83,3%.
