A method of applying paste material to a substrate and supplementing application of paste material to a paste deposit of the substrate, controller, computer program product and screen printer

摘要

A method for applying paste material (30) to a substrate (20) and for applying paste material (30) to a paste deposit (13) of the substrate (20) in a screen printer (100) for fastening a component (23) to the substrate (30). 20), comprising the steps of: - initially applying paste material (30) to the substrate (20) at at least one paste material position (43), - detecting a three-dimensional structure of a paste deposit (13) at the at least one paste material position (43 ), - making a comparison between the detected three-dimensional structure and a desired structure, and - supplementary application of paste material (30) on the at least one Pastendepot (13) by means of a dispenser (60) depending on the performed comparison, characterized in that the three-dimensional structure of the paste deposit (13) is detected by means of a camera (50) which, prior to the initial application of the paste material (30), for aligning the substrate ats (20) is used in the screen printer (100).
