WebThe first step in helium fine leak testing is to pressurize the sealed package in a 100% helium atmosphere also known as "bombing ", and if the part has a leak some of the gas will enter through the leak path. The amount of helium that penetrates the package will depend on the size of the leak channel, the bomb time and bomb pressure. WebJIS-Z2331 defines 8 major methods. (1) Spray Method ・To detect helium coming inside the test object by spraying helium with a spray gun after evacuating the inside of the test object. ・Suitable for finding a small leak point, applying to finding a relatively small leak.

These effects were seen between 23 and 100 °C after and during helium exposure at relatively low pressures of 140 to 380 kPa. Similar effects were not observed for hydrogen, argon and air. WebThis can be explained by considering the amount of helium entering a sensor package during helium bombing. Because partial pressure difference is what drives the movement of helium through the leak, more helium can get into the package cavity over a short time (e.g. 200 psi difference) than can get out (e.g. less than 1 mTorr difference). navigant credit union warwick plaza
