摘要： A system for accurately dispensing controlled amounts of viscous material. The system includes a pressurized supply of the viscous material, a dispenser connected with the pressurized supply and a feedback control for ensuring that a discrete dispensed amount corresponds closely to the desired dispensed amount for a particular application. The different methods of feedback control include changing pressure of the pressurized supply after measuring a dispensed amount and comparing the dispensed amount with a stored value representing the desired amount. Another manner of feedback control includes changing an air operating pressure associated with the dispenser. A third type of feedback control includes adjusting the duration that the dispenser is maintained on to dispense the viscous material. Each of these types of feedback control are preferably used in succession, as necessary, to ensure that the desired amount of viscous material is discharged from the dispenser. Methods of controlling an amount of viscous material discharged from a dispenser further include using one or more of the feedback controls described above.

摘要： A system for dispensing a viscous material onto a substrate which includes a dispensing element, a viscous material reservoir and a metering device coupled between the reservoir and the dispensing element for metering a variable amount of a viscous material through the dispensing element. The dispensing element and metering device can be moved by a positioner along a predetermined pattern adjacent a surface of a substrate. A weigh scale located adjacent the substrate receives a metered amount of the viscous material and produces signals representative of a variable weight of the material dispensed during a predetermined time interval. A controller adjusts a speed of movement of the positioner along the predetermined pattern to cause the dispensing element to dispense a desired amount of material based on a calculated flow rate. Alternatively, the controller adjusts a rate of delivery of the metering device based on the calculated flow rate to cause the dispensing element to dispense the desired amount of material along the predetermined pattern. Closed loop temperature control may be provided for the dispensing element and/or the substrate to ensure a substantially constant viscosity and a substantially constant flow rate. A prime and purge station may be provided adjacent the substrate for sucking air bubbles from the dispensing element and metering device.

摘要： A method of underfilling a space between a semiconductor flip chip and a substrate to encapsulate a plurality of electrical connections with a viscous underfill material. The flip chip is mounted to the substrate with a plurality of electrical connections thereby forming a gap between opposed surfaces of the flip chip and substrate. The viscous underfill material is dispensed adjacent at least one edge of the flip chip. The flip chip and substrate are the rotated to move the underfill material into the gap under the influence of centrifugal force. The underfill material is cured after fully encapsulating the electrical connections.

摘要： An auger type liquid dispenser accommodates floating head operation by using a floating coupling along the dispensing axis between the motor drive shaft and a pump body coupling which holds the dispensing auger within the pump body in alignment with the dispensing axis, the floating coupling being variable in axial dimension to accommodate relative axial movement between the pump body coupling and the drive shaft during “floating head” dispensing. An auger cartridge removably connects to the pump body via a quick release engagement lever which radially and axially holds the auger cartridge relative to the pump body. This structure facilitates torque transmission to the auger while reducing wear, and the quick release lever facilitates connection to and disconnection from the valve body. The dispenser flowpath includes a frustoconically shaped transition portion residing adjacent the inlet to promote liquid flow without clogs. A linear bearing operatively connects the “floating” pump body to a mounting surface which is parallel to the dispensing axis, to promote smoother “floating” and reduced friction.
摘要翻译：螺旋式液体分配器通过使用沿电动机驱动轴和泵体联接器之间的分配轴线的浮动联接器来适应浮动头操作，泵体联接器将分配螺旋推运器保持在泵主体内与分配轴线对准，浮动联接器可变轴向尺寸以在“浮动头”分配期间适应泵主体联接器和驱动轴之间的相对轴向运动。螺旋推运筒通过快速释放接合杆可拆卸地连接到泵体，该快速释放接合杆相对于泵体径向地和轴向地保持螺旋推运器。这种结构有助于扭矩传递到螺旋推运器同时减少磨损，并且快速释放杆便于连接到阀体和与阀体断开连接。分配器流路包括驻留在入口附近的截头圆锥形过渡部分，以促进没有堵塞的液体流动。直线轴承将“浮动”泵主体与平行于分配轴线的安装表面可操作地连接起来，以促进更平滑的“浮动”并减少摩擦。

摘要： A air jet source is used in conjunction with a micro-extrusion printhead assembly in a micro-extrusion system to bias extruded material onto a target substrate. The printhead assembly utilizes paste valves or other feed system to push/draw an extrusion material through dispensing orifices defined on an extrusion needle, nozzle or stacked plate printhead as the printhead assembly is moved over the substrate. The air jet source is positioned near the dispensing outlets, and directs a gas jet against the extruded material such that the extruded material is reliably biased against the target substrate. Multiple dispensing orifices are defined in a paste dispensing needle to improve starts and stops, as well as improving overall ink distribution. Two independently activated air sources and multiple air jet outlets are utilized to improve control over the quality of bus bars formed by the extruded material.
