Abstract
PURPOSE: To accurately decide the presence or not of any pinhole in a state where there are substantially no disturbances by evaporating volatile materials deposited on the surface of hermetic packges and cooling and recovering the same.
CONSTITUTION: Hermetic packages A are disposed in the 1st chamber 1 and the first chamber 1 is made airtight; at the same time, it is evacuated by an evaporating vacuum suction device 2 to evaporate volatile materials such as moisture, oil, and volatile material deposited on the surface of the packages. The evaporated materials are frozen and recovered into a cold trap 3 provided in the 1st chamber 1, whereby the volatile materials on the hermetic packages A are removed. Next, the packages A are led into the 2nd chamber 4 and the 2nd chamber 4 is put in an evacuated state by a measuring vacuum suction device 5, then the pressure rise in the 2nd chamber is measured with a pressure measuring device 6, whereby the pressure or not of any pinhole is detected.
