    Abstract: A stencil printer includes an electronic substrate support configured to support an electronic substrate and move the electronic substrate between a lowered position and a raised position. The stencil printer further includes a stencil shuttle assembly configured to support a stencil and to move the stencil 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 printer further includes a print head configured to engage the stencil to dispense a material onto the substrate during a print stroke. The stencil printer further includes a drive assembly configured to move the print head to perform the print stroke and configured to selectively move the stencil shuttle frame between the first and second positions.

    Abstract: 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.

    Abstract translation: 用于在电子基板上印刷粘性材料的模板印刷机包括其中形成有孔的模板，以及位于模板上方并构造成将粘性材料沉积在模板孔内的打印头。 打印头包括限定细长室的壳体，限定通道的源端口，该通道具有定位成允许粘性材料流入细长室的入口，一对叶片，其限定了提供出口的狭缝，粘性材料可从该出口流出 细长的柱塞可在细长室中移动以减小细长室内的粘性物质的体积，以及至少一个传感器以检测细长室内的粘性物质的压力。
