Problems solved by technology

The disadvantage of gravure printing is that the method has so far hardly been translated for high-volume technical applications, and thus the achievable limits are still unknown
Furthermore, the possibilities for variable, precise material transfer to the printing plane have hitherto been limited

Embodiment Construction

[0026] figure 1 A schematic illustration of a device 1 for producing a printing cylinder 3 according to the invention, which is used to realize an electronic circuit (here a thin-film solar cell circuit) in printing technology, is shown. The digitally created circuit template 5 colored with a predefined gray gradient is post-processed in the processing unit 9 according to a predetermined processing algorithm. From said processing unit 9 the data obtained reach a laser control unit 11 which controls a processing laser 13 which generates a processing laser beam 13a not only in terms of the instantaneous laser beam energy but also in terms of the orientation of the laser beam . This is done by creating, on the surface of a printing cylinder prototype rotating at a constant speed, a configuration consisting of printed depressions with a predetermined transverse profile and a corresponding local predetermined depth, which after using a suitable printing paste and a suitable post-t...

Abstract

The present invention relates to a method used for manufacturing an electronic circuit, a printing roller and a method for manufacturing the same. A method for manufacturing an electronic circuit by using a printing roller, wherein the electronic circuit comprises a plurality of circuit components with predetermined sections, the printing roller has a coating with low surface energy, a plurality of delimited printing sags are formed in the coating, the printing sag has a sag volume which is accurately adjusted corresponding to the predetermined section of the circuit component, wherein, in the process of printing, printing liquid contained in the printing sags is completely transferred onto a circuit substrate.

Description

technical field [0001] The invention relates to a method for manufacturing an electronic circuit comprising a plurality of circuit elements having a predetermined cross-section. Furthermore, the invention relates to a printing cylinder that can be used in such a method, and finally to a method for producing such a printing cylinder. Background technique [0002] Printing technology has been gaining increasing attention in the last few years for this method, especially after inkjet printing technology has proven to be suitable for manufacturing technical products outside of the original field of application, for example in textile technology. [0003] With the print quality required in gravure printing, it is not practical to use this printing method for technical applications. Especially the scanning and localization accuracy is relatively coarse in graphics applications (resolution of the human eye is ~100 μm spot size at a viewing distance of 50 cm). Very precise pigment...
