ELECTRIC PROPERTY TESTER FOR FPD SUBSTRATE HAVING FUNCTION PREVENTING DAMAGE FROM STATIC ELECTRICITY

摘要

PURPOSE: An electric property tester for an FPD substrate having a function preventing damage from static electricity is provided to remove static electricity of low voltage remaining on the surface of the FPD substrate. CONSTITUTION: In an electric property tester for an FPD substrate having a function preventing damage from static electricity, an electrical property test(200) having an SMU terminal connected to a signal transmission cable. A probe station(100) including a probe pin and a probe card assembly. A first relay which is contacted to the probe pin is connected to the signal transmission cable. A discharge circuit discharge static electricity which is induced in a substrate when the probe pin is contacted to the substrate.
