| Abstract: | The possibility of testing the electrical conductivity of soldered joints using and eddy-current transducer has been studied.
The simplest model calculations allowing evaluation of the relative value of a signal from an inhomogeneity depending on its
location inside a specimen are presented. It is shown that signals yielded by an eddy-current transducer are quite informative
for determining the quality of soldering of current-carrying joints. |
