Title: METHOD AND APPARATUS FOR CONTROLLING JET DISPENSING BY DISPLACEMENT MEASUREMENT
Abstract:
A method for jetting a viscous medium onto a substrate (23) is disclosed. The method comprises providing (110) viscous medium to a jetting chamber (5) of an ejector (1), operating (120) an impacting device (6, 7) to impact a volume of the viscous medium in the chamber such that viscous medium is jetted through a nozzle (4), connected to the chamber, towards the substrate, and monitoring (130) a displacement of the impacting device during the impact. An ejector and a system comprising such an ejector and a control unit (32) is also disclosed. The monitoring of the displacement allows for the operation of the impacting device to be controlled accordingly, thereby providing for an improved control of the jetting process.
