Process and device for generating test patterns when applying solder paste by a screen process on printed circuit boards

摘要

The invention relates to a method and an apparatus for generating test patterns during the application of solder paste to printed circuit boards by means of the screen-printing process, a structure being optically recorded as a reference pattern in a teach-in method step and this recording being used to generate reference data for the test patterns. It is provided that the printing stencil for the screen-printing process is optically recorded as the structure.
