Pressure screen for technical screen printing in substrate of solar cell, has one group of fabric threads that are run transverse to another group of fabric threads and parallel to longitudinal direction of print image aperture

摘要

The pressure screen comprises a wire cloth (2) that is clamped in a clamping frame. A structural layer (3) such as photo-emulsion layer is provided with a print image aperture (4a) corresponding to a print pattern and is extended along a longitudinal direction of the wire cloth in strip form. Two groups of parallel fabric threads (2a,2b) are arranged in the wire cloth. The fabric threads (2a) are run transverse to the fabric threads (2b) and are run parallel to the longitudinal direction of the print image aperture.
