Abstract:
1. 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 for the frame, to deposit viscous material over the stencil; a substrate support constructed and arranged to hold the substrate; and a control apparatus for controlling movement of at least one of the stencil, the print head and the substrate support along multiple axes of motion, the control apparatus comprising wherein the first relay is configured to be manipulated in response to the actuation signal between a first state in which the switch is electrically connected to the first contact and a second state in which the switch is electrically connected to the second contact; wherein the first and second motors are coupled to the substrate support to provide movement of the substrate support; wherein the first relay comprises an additional contact coupled to the direct current source; and wherein the first relay is constructed and arranged such that when the relay is in the first state, the direct current signal is applied to the second motor.
