A stencil printer for printing viscous material on a substrate , the stencil printer comprising: a frame ; a stencil coupled to the frame ; a print head , coupled to the frame , to deposit and print viscous material over the stencil; a lift table assembly configured to support the substrate in a transport position and a print position; and a conveyor system including a pair of rail members coupled to the frame , the pair of rail members extending through the frame and being configured to transport the substrate through the stencil printer , and for each rail member , a lift tool assembly coupled to the rail member , the lift tool assembly being configured to cooperate with the lift table assembly and to engage and support the substrate at a transport height and a print height, the lift tool assembly including a lifter portion , a main plate secured to the lifter portion , a clamping member coupled to the main plate , the clamping member being configured to move horizontally between a substrate engaged position and a substrate disengaged position, and a thin foil coupled to the main plate , characterized in that the thin foil is configured to move vertically and horizontally, independent from the clamping member , between an engaged position, in which the thin foil is moved horizontally to extend over an edge of the substrate and vertically to engage a top surface of the clamping member , and a retracted position, in which the thin foil is moved horizontally away from the substrate and vertically toward the main plate . a frame ; a stencil coupled to the frame ; a print head , coupled to the frame , to deposit and print viscous material over the stencil; a lift table assembly configured to support the substrate in a transport position and a print position; and a conveyor system including a pair of rail members coupled to the frame , the pair of rail members extending through the frame and being configured to transport the substrate through the stencil printer , and for each rail member , a lift tool assembly coupled to the rail member , the lift tool assembly being configured to cooperate with the lift table assembly and to engage and support the substrate at a transport height and a print height, the lift tool assembly including a lifter portion , a main plate secured to the lifter portion , a clamping member coupled to the main plate , the clamping member being configured to move horizontally between a substrate engaged position and a substrate disengaged position, and a thin foil coupled to the main plate , characterized in that the thin foil is configured to move vertically and horizontally, independent from the clamping member , between an engaged position, in which the thin foil is moved horizontally to extend over an edge of the substrate and vertically to engage a top surface of the clamping member , and a retracted position, in which the thin foil is moved horizontally away from the substrate and vertically toward the main plate . a lifter portion , a main plate secured to the lifter portion , a clamping member coupled to the main plate , the clamping member being configured to move horizontally between a substrate engaged position and a substrate disengaged position, and a thin foil coupled to the main plate , <EOS>
