  • Technical Article: Air Under Water (AUW) - Also known as the "Bubble Test" / Dye Penetrant Leak Test
    AUW, also referred to as the "bubble test," may be okay for medium and large leaks, but is poor for SPC and correlation to other leak test methods is almost impossible. AUW can be used to detect
  • High Throughput Leak Detection
    Various methods have historically been used to check leaks in systems and components from bubble tests to rotameters and pressure loss detection. While these traditional methods have their place, they each have serious drawbacks in accuracy, throughput, and automation.

    of the test equipment available. The limited dynamic range of conventional helium leak detectors required that a secondary test procedure be developed to cover the large, or gross, leak range. Several methods have been tried, and the most commonly used procedure, referred to as the bubble test, involves

    incidental fluid exposure or as complex as a full-penetration fusion weld for bioimplants such as pacemakers. Hermetic seals can be characterized by a variety of test methods, from standard pressure-decay or bubble-emission tests to sophisticated mass spectrometer or radioactive analyses. Because all
  • MICRO: Tool/Fab Support
    Mutsuhiro Amari, Aiwen Wu, and Hee Jun Yang, Linda Chen, Thomas Bowling, and Michael Watt, Particulate- and bubble-induced defects cause distinct problems for 193-nm photoresist systems. Microbridging defects in the photoresist and cone defects in antireflective coatings are particularly

    stream that they want to de-bubble, or remove dissolved oxygen, carbon dioxide, or other gases from this product works great in the flow ranges for which it was designed. Customers that have fluids other than water may need to purchase one of these devices to test applicability. We know that ink

    struggle with the possibility of false-positive results when performing sterile integrity testing (bubble-leak or dye-penetration tests) on a flexible sterile barrier system (SBS) containing porous materials. A false positive can occur when a flexible pouch containing a porous material is bent, folded
