Abstract

Provided are a pump position feedback type dispenser and dispensing method, in which an image of a work, to which a viscous liquid is to be dispensed, is captured to determine an accurate position and direction of the work, and then a position of a pump is received in real time so as to dispense the viscous liquid to the work while ensuring that the pump reaches the accurate position of the work.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2015-0151759 filed with the Korean Intellectual Property Office on October 30, 2015, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to pump position feedback type dispensers and methods of dispensing, and more particularly to pump position feedback type dispensers and methods of dispensing in which capturing will dispense viscous liquids ) of the workpiece to determine the exact position and orientation of the workpiece, and then receive the position of the pump in real time for dispensing the viscous liquid to the workpiece while ensuring that the pump reaches the exact position. Background technique [0004] In an underfill process performed by coating a semiconductor chip with a viscous liquid or a process of coating a light-emitting diode (LED) with a phosphore...
