Method of stenciling with a magnetic stenciling apparatus
A method of stenciling a stenciled graphic in a desired position and orientation on the graphic-display surface of a substrate includes providing at least one stencil template defining the stenciled graphic and at least one guide element including mutually-space template positioning indicia. Both the stencil template and the guide element are magnetically attracted to the substrate. The guide element is magnetically affixed to the graphic display surface in a desired location and orientation. The stencil template is magnetically affixed to the graphic-display surface in a location selected with positioning reference to at least one template-positioning indicium of the guide element. With or without the guide element still affixed, pigment is applied to the graphic-display surface through the at least one stencil template to impart to the graphic-display surface the desired stenciled graphic. The at least one stencil template is then removed from the graphic-display surface.
Multi-functional print head for a stencil printer
A stencil printer includes a frame, a stencil coupled to the frame, and a support assembly coupled to the frame, with the support assembly including tooling configured to support the electronic substrate in a print position beneath the stencil. The stencil printer further includes a print head assembly coupled to the frame in such a manner that the print head assembly is configured to traverse the stencil during print strokes. The print head assembly includes a squeegee blade assembly and at least one paste cartridge to deposit solder paste on the stencil. The stencil printer further includes an end effector configured to pick up and release items from a tooling tray. The stencil printer further includes a movable cart configured to interface with the stencil printer to deliver changeover and/or replacement items within a stencil printer.
REUSABLE COMPOSITE STENCIL FOR SPRAY PROCESSES
Reusable composite stencils for spray processes, particularly for spray processes used in the fabrication of integrated circuit devices, may be fabricated having a permanent core and at least one sacrificial material layer. Thus, in operation, when a predetermined amount of the sacrificial material layer has been ablated away by a material being sprayed in the spray process, the remaining sacrificial material layer may be removed and reapplied to its original thickness. Therefore, the permanent core, which is usually expensive and/or difficult to fabricate, may be repeatedly reused.
THREE-DIMENSIONAL SCREEN PRINTING METHOD, COMPONENT PRODUCIBLE BY MEANS OF SAID METHOD, AND SCREEN PRINTING MASK
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.
Reinforced tensioning frame
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.

Restretchable stencil frame
The restretchable stencil frame according to the present invention consists of a metallic stencil foil mounted on a rectangular frame fabricated of tubular material or C-channel. Each corner of the frame is provided with one screw-actuated conical expander and one counterplate serving to biaxially tension the stencil foil. To ensure uniform stretching of the stencil foil, areas of increased elasticity are provided to the corners of the frame and to the foil itself in the form of oriented slots, cuts, holes and combination thereof.
ENVELOPE LINER TEMPLATE
An envelope liner template having a first panel having a pattern inscribed therein and a second panel. The second panel is positioned below the first template and attached by a fastening mechanism. The fastening mechanism is adapted to secure a decorative sheet in place between the first panel and the second panel when a cutting implement cuts through the pattern and the sheet against the second template panel to form an envelope liner.
SELF-CONTAINED STENCILING KIT FOR PRODUCING MULTICOLOR AND/OR UNICOLOR COMPOSITE IMAGES
The present disclosure relates to a self-contained stenciling kit for producing multicolor and/or unicolor composite images on a target surface, such as a piece of paper. The present disclosure also relates to a method of using the self-contained stenciling kit to produce a multicolor and/or unicolor composite image on a target surface.
