Abstract: A stencil printer (10) includes a stencil (18), a material applicator (20) to apply material on the stencil (18), and a stencil wiper assembly (34) to selectively wipe the stencil (18). The stencil wiper assembly (34) includes has a quick-change material module (38) having a supply roller (46) to receive a roll of material, a take-up roller (48) to receive used material, a drive (52) to move the material across the stencil (18) from the supply roller (46) to the take-up roller (48), and a controllable tension device (14) configured to vary a tension of the material when driving the material from the supply roller (46) to the take-up roller (48).

Abstract: A stencil printer (10) includes an electronic substrate support (22) configured to support an electronic substrate (24) and move the electronic substrate between a lowered position and a raised position. The stencil printer further includes a stencil shuttle assembly (18) configured to support a stencil (16) and to move the stencil between a first position in which the stencil is positioned toward a front of the stencil printer and a second position in which the stencil is positioned toward a back of the stencil printer. The stencil printer further includes a print head (20) configured to engage the stencil to dispense a material onto the substrate during a print stroke. The stencil printer further includes a drive assembly configured to move the print head (20) to perform the print stroke and configured to selectively move the stencil shuttle assembly (18) between the first and second positions.

Abstract: A stencil printer for printing viscous material on an electronic substrate includes a stencil having apertures formed therein, and a print head positioned over the stencil and configured to deposit viscous material within the apertures of the stencil. The print head includes a housing defining an elongate chamber, a source port defining a passage having an inlet positioned to allow viscous material to flow into the elongate chamber, a pair of blades defining a slot that provides an outlet from which viscous material can flow out of the elongate chamber, an elongate plunger movable in the elongate chamber to reduce a volume of viscous material within the elongate chamber, and at least one sensor to detect pressure of the viscous material within the elongate chamber.
