Active Testing of Electronic Components

During testing, the infrared image reveals an electronic component pulsed with a current pulse. The clearly visible hot-spot is an indicator of a defective part. The aim of the quality control is to check whether the wire has defects or breaks. To do this, the resistor is pulsed with a pulse current for a short time (a few ms), with a thermal image being taken at an exactly defined point in time after the current pulse has been applied. Defects are clearly identifiable in the image: if the wire has breaks, there will be no warming. Defects in the wire lead to localised temperature increases (hot spots). The thermal image is analysed in a fully automatic process using the IrControl software, giving out a “good” or “bad” signal as appropriate.
