Abstract:
A print head assembly (20) of a stencil printer (10) includes a print head frame (36) and a wiper blade assembly (74) coupled to the print head frame. The wiper blade assembly includes wiper blades (78) that contact the stencil (18) to print solder paste onto the stencil during a print stroke. The wiper blades (78) are configured to force solder paste through the apertures of the stencil (18). The print head assembly (20) further includes a dispensing unit (56) coupled to the print head frame (36). The dispensing unit (56) is disposed between the wiper blades (78) to deposit solder paste between the wiper blades. The dispensing unit includes a cartridge receiver (66). The print head assembly (20) further includes a cartridge (68) positioned in the cartridge receiver (66) and a sensor (80) coupled to the print head frame (36) proximate the cartridge (68). The sensor (80) is configured to measure a temperature of the cartridge (68).
Abstract:
A stencil printer (10) includes a stencil shuttle assembly (18) coupled to a frame (12). The stencil shuttle assembly is configured to move the stencil (16) in an x-axis direction 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 shuttle assembly (18) further is configured to move the stencil (16) in a y-axis direction to align the stencil. The stencil printer further includes a wiper (164) to remove material from the stencil as the stencil is translated away from the substrate (24) by the stencil shuttle assembly. The stencil shuttle assembly, when the stencil is translated away from the substrate, is configured to move the stencil (16) in the y-axis direction in an oscillating manner. Methods of cleaning a stencil are further disclosed.
