Abstract: A print head assembly of a stencil printer includes a print head frame and a wiper blade assembly coupled to the print head frame. The wiper blade assembly includes wiper blades that contact the stencil to print solder paste onto the stencil during a print stroke. The wiper blades are configured to force solder paste through the apertures of the stencil. The print head assembly further includes a dispensing unit coupled to the print head frame. The dispensing unit is disposed between the wiper blades to deposit solder paste between the wiper blades. The dispensing unit includes a cartridge receiver. The print head assembly further includes a cartridge positioned in the cartridge receiver and a sensor coupled to the print head frame proximate the cartridge. The sensor is configured to measure a temperature of the cartridge.

Abstract: A dispenser, configured to dispense material on a substrate, includes a dispensing unit having a housing with a chamber, a piston disposed in the chamber and axially movable within the chamber, and a nozzle coupled to the housing. The nozzle has an orifice co-axial with the chamber of the housing. The dispenser further includes an actuator coupled to the dispensing unit and configured to drive the up- and down movement of the piston, and a compliant assembly coupled to the actuator and the piston. The compliant assembly is configured to permit limited relative travel between the actuator and the piston. A method of dispensing is further disclosed.
