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.

A stencil printer for printing viscous material on a substrate includes a frame, a stencil coupled to the frame, and a print head, coupled for the frame, to deposit and print viscous material over the stencil. The stencil printer further includes a substrate supporting and clamping assembly to support and clamp a substrate in a print position. The substrate supporting and clamping assembly includes at least one support member to support the substrate in a print position, a pair of rail members, coupled to the frame, adapted to engage opposite edges of the substrate, and a clamping mechanism, coupled to the frame, to move at least one of the rail members against the substrate to clamp the substrate. The clamping mechanism includes at least one piston to move the at least one of the rail members between a first position in which the rail member is spaced away from one of the opposite edges of the substrate and a second position in which the rail member engages one of the opposite edges of the substrate to clamp the substrate between the rail members during a print operation. The clamping mechanism further includes a pressure regulator to control a clamping force applied by the piston to the rail member against the edge of the substrate.

A stencil printer for printing viscous material on a substrate includes a frame, a stencil coupled to the frame, and a print head, coupled for the frame, to deposit and print viscous material over the stencil. The stencil printer further includes a substrate support to support a substrate in a print position and a substrate clamping assembly to clamp the substrate in the print position. In a certain embodiment, the substrate clamping assembly includes a pair of rail members coupled to the frame. The rail members are adapted to engage opposite edges of the substrate. The substrate clamping assembly further includes a pair of foils, one for each rail member, with each foil being releasably secured to the rail member in a position so that the foil overlies the substrate. The substrate clamping assembly also includes a pair of clamping members, one for each rail member and foil, to releasably secure the foil in place on the rail member.

A stencil printer apparatus is provided. The stencil printer apparatus may include a stencil, a material applicator to apply material on the stencil, a supply roller configured to receive a roll of web-material, the supply roller comprising a first shaft, a take-up roller to receive a roll of web-material, the take-up roller comprising a second shaft, at least one spring-loaded protrusion element associated with one of the first shaft and the second shaft, and a drive configured to move web-material across the stencil between the supply roller and the take-up roller, and a frame to support the supply roller, the take-up roller and the drive. The at least one spring-loaded protrusion element may be configured and arranged on the at least one of the first shaft and the second shaft to resiliently engage at least one web-material core around which web-material may be disposed. Other embodiments and methods ate provided.
