Removal of backcoat on substrate e.g. glass substrate, involves warming up surface area of edge of back of substrate by electron bombardment for evaporation of solitary particles

摘要

#CMT# #/CMT# The backcoat on a substrate (2) formed by vacuum coating is removed by warming up the surface area of the edge of back (6) of substrate by electron (14) bombardment for evaporation of solitary particles, by freeing the back of substrate with undesired coating (5) by using superficial energy input. #CMT# : #/CMT# An independent claim is included for arrangement for removing backcoat on substrate. #CMT#USE : #/CMT# Removal of backcoat on substrate e.g. glass substrate. #CMT#ADVANTAGE : #/CMT# The method enables easy and economical removal of backcoat on substrate. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the coating with front face of substrate lying down. 2 : Substrate 5 : Undesired coating 6 : Back 8 : Hot cathode 14 : Electron.
