Conventional Leak Detection and Seal Testing

Rink International uses a conventional krypton-85 radioisotope (Radiflo®) and helium mass spectrometry (HMS) leak-detection equipment together with Fourier Transform Infrared (FTIR) spectrometry to perform hermetic testing and analysis of microelectronic components and related technologies. Our advanced equipment also allows us to analyze the physical and chemical characteristics of miscellaneous compounds.

Advanced Leak Detection and Seal Testing

Rink International performs leak testing of pressure vessels and advanced microelectronic technologies, as well as high-sensitivity leak-rate testing. The state-of-the art radioisotope detection equipment we have developed for these tests supports hermetic testing at high pressures (up to hundreds of atmospheres) while maintaining the rapid cycle times necessary to support the needs of high-volume manufacturing operations.

High-pressure vessels we test

Combustion / Internal Ballistics / Propulsion Testing and Analysis

Rink International specializes in testing energetic devices such as gas generators, initiators, primers and energetic materials over a wide range of conditions. For enhanced testing, we use high-pressure calorimeters and strand burners, pyro-valve devices, ballistic gas compressors and other experimental apparatuses. By carefully analyzing our test data, we are able to uncover important insights about the underlying thermochemical processes that affect the performance of the devices under test.

Other Unique Technologies

With the financial support of NASA, Rink International is currently developing a family of innovative, small-volume moisture standards to address an important need within the microelectronics manufacturing community. These standards will inform the calibration and validation of RGA systems used to assess the internal contents of microelectronic packages, implantable medical devices, MEMS (micro-electromechanical systems) and other technologies.

Consulting / Education

Rink International offers consulting services for and short courses on hermeticity testing and internal ballistics. Our courses cover leak detection and its relationship to the underlying fundamental principles of fluid mechanics, gas dynamics and thermochemistry.
