Abstract
The aim of the invention is to simplify and improve the production method for circuit arrangements that are mounted on a support element ( ), said element having thermal through-platings ( ) which are at least partially scaled by a screen printing process. To this end, the screen printing process is carried out after the application of a first metallization layer ( ) to the support element ( ) which forms the base metallization layer, whereby the residue of the screen printing material ( ) remaining on the underside ( ) of the support element ( ) is stripped once the screen printing material ( ) has been cured, using at least a mechanical cleaning process and/or a chemical cleaning process.
