Abstract:
The present invention relates to a method of manufacturing low-density gas-filled disk drives involving test equipment utilized to determine gas leaks occurring in disk drives subjected to shock and vibration events. A disk drive is placed in a sealed container, which, in turn, is connected to a gas detection device. Following shock or vibration testing, the gas detection device determines if a leak has occurred, as well as the quality of gas leaked from the disk drive. The present invention also involves a test apparatus designed to check the accuracy and calibration of associated gas detection devices used during the shock and vibration tests. The test apparatus utilizes a sealed test chamber containing a known quantity of gas, which is released during a test event. Knowing the quantity of gas released, the output of the gas detection device can be monitored and calibrated as needed.
