A printing apparatus includes a base frame being bridged between a pair of legs and being configured to support a printing unit, and a board box being arranged under the base frame and being configured to accommodate a control board. A hook is provided to any one surface of a lower surface of the base frame and an upper surface of the board box, and a hole engageable with the hook is provided in the other surface. A female screw is formed in any one side surface of a side surface of the base frame and a side surface of the board box, and a fixing member configured to abut against the one side surface is provided to the other side surface. The board box is fixed to the base frame by a male screw screwed into the female screw through intermediation of the fixing member.

A stencil for use in stenciling complex symbols incorporates a stencil substrate employing a flexible material, having a plurality of symbols arranged thereon. A plurality of folding stiffeners are incorporated in the substrate, each stiffener being positioned to split symbols having stencil cutouts forming isolated elements within an interior of the symbol. The stiffeners are foldable about a vertex, to collapse into a raised position and bring together the split symbol, with the stiffeners supporting the isolated elements created by the cutouts and portions of the stencil cutouts forming the symbols that extend into coincident channels in the folding stiffeners, to bridge adjoining portions of said split characters.

A printed wiring board has conductor patterns (12) having a thickness (t1) of 50 m or more on an insulating substrate (11). An insulating layer (5) is provided in regions (L) on the conductor patterns and on the insulating substrate in regions (S) between the conductor patterns. A thickness (t.sub.L) of the insulating layer on the conductor patterns is preferably 0.1-1 times the conductor thickness (t.sub.1). The insulating layer is formed on the conductor patterns and on the insulating substrate between the conductor patterns by printing a resin composition using screen printing and then curing the resin composition. The resin composition has a viscosity of 50-300 P at 25 C. and a thixotropic index of 1.1-3.5. A screen printing plate used for screen printing has a mesh thickness of 2.2 or more times a yarn diameter of yarns.

A composite stencil for applying designs to walls and other surfaces is disclosed. The stencil includes a porous textile support layer to which a flexible stencil mask is bonded by an adhesion layer. The support layer supports unconnected parts of the stencil mask without bridges common with traditional stencils. Further, the textile support layer in the open areas of the stencil can be colored with a sublimation dye to suggest to a user the colors that should be applied in the various areas of the stencil. A pressure sensitive adhesive is applied to the back of the stencil. In use, the stencil is removably adhered to a surface by the pressure sensitive adhesive, whereupon paint or other pigment is applied through the textile support layer to the surface. The lack of bridges permits the entire design to be applied with a single stencil in a single session. The stencil is cleanable and reusable to apply additional designs.

A movable cart includes a housing configured to move along a horizontal surface and a plurality of shelves supported by the housing Each shelf of the plurality of shelves is configured to move between a retracted in which the shelf is positioned within the housing and an extended position in which the shelf extends from the housing. The movable cart further includes a sensing system configured to determine whether each shelf of the plurality of shelves is in the retracted position and a type of item supported by the shelf. Other aspects of the movable cart are further disclosed.

A stencil printer includes a frame, a stencil, a support assembly, and a print head, 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 support assembly supports the electronic substrate in a print position beneath the stencil. The print head assembly includes a print head a squeegee blade assembly configured to roll solder paste along the stencil. The stencil printer further includes a cover coupled to the frame to enclose operating components of the stencil printer, including the stencil, the support assembly, the print head gantry and the print head assembly. The cover includes an elongate opening formed therein and a movable door configured to selectively close the elongate opening. The elongate opening is sized to enable the stencil and/or a tooling tray to pass through.
