Abstract
A system for dispensing a viscous material includes a motion system for controlling movement of a dispensing tip within a dispensing region and delivering a viscous material at a controlled flow rate in coordination with the dispensing tip movement in order to deliver a predetermined amount of the viscous material to predetermined positions within the dispensing region. A dispensing tip in fluid communication with a pump for use with the system includes outer and inner housings and outlet holes within a space between them. A contact element within the inner housing is capable of contacting a suitable surface for dispensing viscous material. In some embodiments, a face of the outer housing located a fixed distance from an apex of the contact element maintains a uniform thickness during dispensing. A method of using the system includes controlling the movement of the dispensing tip and the flow rate of the viscous material.
