DIRECT TO MESH SCREEN STENCIL CREATION

A direct to mesh (DtM) screen printer for creating a screen stencil is provided. The DtM screen printer includes a frame to hold a pre-stretched mesh in place during application of a jettable emulsion, a fixture to hold the frame, a platen to hold a release fluid against one side of the pre-stretched mesh, a fluid dispenser for dispensing the release fluid onto the platen or mesh, and a printer carriage supporting a print head for printing the jettable emulsion on a side of the pre-stretched mesh opposite the platen. A process is also provided, the process being for using the DtM screen printer to prepare the screen stencil for screen printing.

Printing mask and method of printing adhesive pattern

The present disclosure provides a printing mask and a method of printing an adhesive pattern with the printing mask. The printing mask includes: a screen including: an annular permeable region through which an adhesive permeates; and a barrier region which surrounds the annular permeable region and stops a permeation of the adhesive through the barrier region, the annular permeable region including an adjustment sub-region configured to increase a permeability of the adhesive, and the barrier region including barrier sub-regions respectively located on an inner side and an outer side of the corresponding adjustment sub-region; a first film covering a side of the barrier region; and a second film covering sides of the barrier sub-regions facing away from the first film.

Manual squeegee system
11167543 · 2021-11-09 ·

The manual squeegee system applies one or more layers of inks to a targeted screen of a manual screen printing device. The manual squeegee system mechanically adjustably fixes the application pressure and the angle of attack of each of the one or more layers of inks. The manual squeegee system comprises a frame, a jib, a trolley, a plurality of slings, and a blade structure. The blade structure applies the one or more layers of inks at a consistent application pressure and the angle of attack. The plurality of slings attach the blade structure to the trolley. The trolley attaches the plurality of slings and the blade structure to the jib such that the position of the blade structure can be adjusted relative to the jib. The jib attaches the trolley to the frame. The frame attaches the manual squeegee system to the manual screen printing device.

Method for gripping variable thickness workpieces in a printing machine

A method of gripping a substantially planar workpiece while providing compensation for variations in thickness is described. During the process, the workpiece is overdriven into a clamping member before clamping force is applied, and the positions of the clamping member before and after application of the clamping force are measured. These measurements are then used to control a compensating movement of the tooling table and optionally a final lift of the conveyance rails.

THREE-DIMENSIONAL SCREEN PRINTING METHOD, COMPONENT PRODUCIBLE BY MEANS OF SAID METHOD, AND SCREEN PRINTING MASK
20230321721 · 2023-10-12 ·

The invention relates to a three-dimensional screen printing method for producing a green part from printing material for a powder metallurgical component, wherein the printing material contains a fraction of powder, more particularly metal powder or ceramic powder, and binder or consists of these materials, characterized in that a screen printing mask has a screen printing structure having openings for pressing the printing material through, the openings being partly undulate so that the green part at least partly has a three-dimensional undulate structure and/or undulate edges.

PRINTING STENCIL FOR PRODUCING A STRUCTURE OF AN ELECTRONIC COMPONENT, IN PARTICULAR OF A PHOTOVOLTAIC SOLAR CELL, AND METHOD FOR PRODUCING A PRINTING STENCIL OF THIS TYPE

A printing form for producing a structure of an electronic component, in particular a photovoltaic solar cell, having a screen frame and a screen, which is in the form of a sheet-like textile and has a multiplicity of elongate screen elements. The screen is arranged in the screen frame and the screen has at least one printing region which a printing paste can permeate and at least one barrier region which the printing paste cannot permeate. The elongate screen elements are made from glass fiber, carbon fiber and/or carbon nanotubes.

Stencil printer with component loading verification system and method

A stencil printer for printing an assembly material on an electronic substrate includes a frame, a stencil coupled to the frame, the stencil having apertures formed therein, a support assembly coupled to the frame, the support assembly being configured to support the electronic substrate, a print head gantry coupled to the frame, and a print head assembly supported by the print head gantry in such a manner that the print head assembly is configured to traverse the stencil during print strokes. The stencil printer further comprises a verification system to determine whether an item placed within the stencil printer is properly installed within the stencil printer.
