APPARATUS FOR SENSING AN ERROR OF A NEEDLE POSITION AND DISPENSING HEAD FOR SEMICONDUCTOR POTTING SYSTEM

摘要

PURPOSE: An apparatus for sensing a needle position error for a dispenser head and a coating head for a semiconductor potting device including the same are provided to prevent the defect of a substrate or chip by simply detecting a needle position error for a dispenser head with two brackets. CONSTITUTION: A first bracket(110) comprises a first sensor. The first sensor has a separation space and surrounds at least part of an outer side of the needle. A second bracket(120) includes a second sensor. The second sensor has the separation space and surrounds the outer side of the needle in an opposite direction to the first sensor. A space controller(150) horizontally move the second bracket and controls a separation distance between the needle and the second sensor. A contact detector detects whether the outer side of the needle is contacted with the first sensor and the second sensor.
