Support blocks for printed circuit boards (PCB's) and printed circuit board assemblies (PCBA's), wherein the support blocks are produced from a 3D printing process. The support block including a bottom surface having a vacuum connection; a top surface having at least one vacuum hole; at least one recessed surface that is offset from the top surface; and at least one vacuum channel extending from the vacuum connection to the at least one vacuum hole.

The invention relates to a system for producing three-dimensional screen-printed articles, comprising a press bed with a printing screen, by means of which at least one printing exploit can be printed multiple times, wherein after each completed printing, the lift-off can be increased by the application thickness of the previous printing.

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.

An apparatus that communicates with a screen printer and a solder inspection device is disclosed. The apparatus according to the present disclosure may include a process that is configured to: obtain first information associated with each of a plurality of pads on the substrate; obtain second information associated with each piece of the solder paste applied to each of the plurality of pads from the solder inspection device; determine a position correction value for the stencil mask with respect to the substrate based on the first information and the second information; and deliver the position correction value to the screen printer.

A screen printing adapter device is disclosed. In an example, the screen printing adapter device includes a body configured as an accessory to a printing board having a tag printing surface. The body is attached to a screen and moves on and off of the printing board along with the screen for a screen printing operation. The body supports areas of the screen for a squeegee that are otherwise unsupported by the printing board. The example screen printing adapter device also includes a shoulder edge of the body shaped to fit adjacent and conform to a shoulder edge of the printing board. The example screen printing adapter device includes a collar edge of the body. In an example, the collar edge of the body is shaped to fit fully around a perimeter of the tag printing surface of the printing board.
