Abstract: A dispensing system includes a frame, a support coupled to the frame, a dispensing unit configured to dispense viscous material, and a gantry assembly coupled to the frame. The gantry assembly includes a gantry configured to support the dispensing unit and to move the dispensing unit in x-axis, y-axis and z-axis directions and a tilt and rotate subassembly configured to tilt and rotate the dispensing unit. The dispensing system further includes a controller configured to control dispensing unit and the gantry assembly to perform a dispense operation on the electronic substrate. The controller is configured to control the dispensing unit to dispense material from the nozzle of the dispensing unit at a flow rate configured to deposit a desired amount or density of material on the electronic substrate along a three-dimensional path.

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.

Abstract translation: 配置成在衬底上分配材料的分配器包括具有壳体的分配单元，所述壳体具有腔室，设置在腔室中并可在腔室内轴向移动的活塞以及联接到壳体的喷嘴。 喷嘴具有与壳体的腔室同轴的孔口。 分配器还包括联接到分配单元并被配置为驱动活塞的上下运动的致动器，以及联接到致动器和活塞的柔性组件。 柔性组件构造成允许致动器和活塞之间的有限的相对行进。 进一步公开了一种分配方法。
