A tensioning frame for tensioning a printing screen comprises struts to reinforce the constituent beams. These may be provided either on a supplementary brace plate or integrally formed with the beam. A shaft may be used to retain engagement bodies within pockets formed in the beam.

A method for manufacturing a flex-tolerant three-dimensional printed antenna suitable for use in an electronic device provides a three-dimensional printed antenna with base layer, radiation layer, through holes, and feeder. The radiation layer includes a first radiation region, at least one second radiation region, and a feed end. A region between the first and second radiation regions is defined as a bent region. The radiation layer is formed by a screen-printing plate by a planar printing process. The through holes on the bent region form a line for bending. The feeder is electrically connected to the feed end. The second radiation region is canted from the bending line with respect to the first radiation region to form the three-dimensional printed antenna. The three-dimensional printed antenna and an electronic device are also disclosed.

Disclosed is a precision cut printing screen in which the features of a printing pattern are defined on a sheet material by a plurality of apertures within a target printing boundary. Also disclosed is a method of making the printing screen.

A method of forming solder paste on an object is provided. The method includes providing a multilayered stencil, each stencil layer having an aperture formed therethrough from a top surface of the respective stencil layer to a bottom surface of the stencil layer. The method also includes applying the stencil to a surface of the object. The method also includes filling a void space formed by a combination of the apertures in the stencil layers with solder paste. The method also includes removing the stencil layers in a sequential manner to leave the solder paste.

Disclosed herein are a system and method for producing paint templates for painting a design on a target surface. The system includes a processor configured to generate a geo-file of paint template designs. The processor includes a design module configured to parse the design into a set of paint sub-designs and a template design module configured to generate the geo-file of paint template designs based on the set of paint sub-designs. The generated geo-file of paint template designs includes a paint template design that corresponds to a paint sub-design. The system further includes a plotter configured to produce a set of paint templates based on the geo-file of paint template designs. Each paint template design includes a set of alignment marks and each paint template is produced with a set of alignment apertures corresponding to the set of alignment marks.

A screen printing form (1, 1′) for use in screen printing, in particular for producing a metallic contact structure of a photovoltaic solar cell, having a woven screen printing fabric (1b) with a plurality of elongate woven fabric elements, which are arranged in a first element direction and a second element direction perpendicular thereto, and a stencil (1c), arranged on the woven screen printing fabric (1b) that has at least one opening formed as straight channel with a channel width BK. The woven fabric elements have a spacing AF in the first element direction and a spacing which deviates by less than 5% from AF in the second element direction, and the woven fabric elements have a diameter DG in the first element direction and a diameter which deviates by less than 5% from DG in the second element direction. A screen printing device and screen printing form are also provided.

The present invention relates to a self-aligning stencil device for producing a multi-color composite image on a target surface. The self-aligning stencil device includes a central panel and a plurality of stencil panels foldably connected to the central panel. The central panel includes a solid region and a cut-out region. The solid region of the central panel includes a front surface and a back surface, and is defined by an outer border of the central panel and an inner border of the central panel. The cut-out region is vacant space that is defined by the inner border of the central panel. Each stencil panel has its own distinct stencil pattern and is foldably connected to a different corresponding portion of the outer border of the central panel, thereby forming a connection fold between each stencil panel and its corresponding portion of the outer border of the central panel. The plurality of stencil panels, when folded at their connection folds upon the central panel, self-align to collectively form a composite image, so that painting each distinct stencil pattern with a different color is effective to yield a multi-color composite image on a region of the surface imposed behind the cut-out region of the central panel. Also disclosed are kits and methods for producing multi-color composite images using the device of the present invention.
