  • DETECTING LEAKS
    Pressure vessels, valves, tanks, heat exchangers, radiators, drums, welds, and gasket integrity are just a few products that require high seal integrity to. insure a reliable leak free product. There are a few ways to insure this integrity, pressure decay or leak testing is the most common. Helium
  • Leak Testing (.pdf)
    , helium is introduced to the exterior of the part and a sensor reads molecules of helium transferred through the part indicating a leak. ./df57746e-515e-4d8a-bb83-0f0da19e15d1. Appl. ication:  Leak Testing. Practic. ally every pressure-containing vessel is leak tested during production or assembly
  • Technical Article: Automotive Leak Testing
    Leak Testing of automotive components or assemblies to newer emission specifications or tighter OEM specifications is challenging. ATC, Inc. has extensive knowledge and experience in the automotive industry, and helped to develop some of these specifications such as fuel and vapor components
  • Leak Testing Meets - New Semiconductor Industry Needs
    Helium leak detectors have evolved quite dramatically in recent years. Thanks to the electronics revolution, expanded features and interface capabilities have become more user friendly and more suitable for advanced applications, such as those found in the semiconductor industry. Manufacturing

The valve type, seal, wattage, and. spring force all play a role in. determining minimum leak rates. Factors to consider that directly. affect leak rates include: • Pressure. Figure 1: GC
  • Medical Device Link . Electrical Testing and Environmental Screening of Hybrid Microelectronic Devices
    leak detector, which measures the rate at which the helium is escaping from the package. A maximum allowable rate has been established that determines whether a part is passing. Gross leak testing repeats the eight-hour pressurization, replacing the helium with an inert liquid. The part
