TESTER OF PACKAGE FOR LEAK TESTER OF PIEZOELECTRIC ELEMENT PACKAGE

PURPOSE: A testing apparatus of a leak testing package of a piezoelectric element package is provided to provide an impedance measuring structure of an aligned piezoelectric element package before and after pressurization. CONSTITUTION: A pair of first and second X-axis rails is horizontally arranged. A pair of shuttle pockets(30) processes different processes by being respectively arranged on the first and second X-axis rails. A bowl bushing(311) is formed under the shuttle pockets to be guided to an upper direction by a pressure unit(313). A pressure spring(32) for restoring an original position of the shuttle pockets is formed under the bowl bushing. The shuttle pockets are moved as a pressurized unit(31) following the first and second X-axis rails. A testing unit(40) performs a leak test of a work about one of the shuttle pockets.
