Various embodiments of the teachings herein include a method for monitoring a flux application in a soldering process. An example includes: defining flux wetting surfaces in relation to an image of an application surface; generating a thermographic recording of the application surface selectively provided with liquid flux; defining adjustment points on the application surface which can be identified on the image and on the thermographic recording; superimposing the image and the thermographic recording on the basis of the adjustment points; and comparing the position of temperature anomalies on the application surface identified by the thermographic recording with the position of the flux wetting surfaces on the image.

Monitoring a flux application

Various embodiments of the teachings herein include a semifinished product for use in the populating of a power electronics component by a connecting method. The product includes an electrically insulating prepreg frame electrically insulated. The prepreg frame is configured for surrounding an applied connecting material at a metallized installation site during the population. A material of the prepreg frame enables simultaneous processability of electrical connection and electrical insulation by compression of the insulation material in the form of the semifinished product since the processing parameters of the electrical connecting material and the semifinished product are compatible.

A carrier plate has test areas for the assessment of a selective soldering process. The carrier plate has different zones, which are provided with peripheral borders. The zones are not wettable with solder, while the peripheral borders are wettable. If a selective soldering head is brought up to the reference areas, then, as long as there is no deficiency in quality, the respective peripheral border must be just wetted with solder, whereby an assessment of the selective soldering process is possible. The test plate advantageously makes a simple optical evaluation possible, for example by visual inspection.
