RGA has been designed to observe contamination in vacuum process. It also controls process. They are used to detect contaminants in low pressure atmosphere of gas. They are also used to determine quality of the vacuum. They are found in those applications that are of high vacuum such as accelerators, surface science set ups and in research compartments. The most easily available kind of this tool is open ion source, but the closed ion source is also available.
Applications apply to a wide range of industries including Microelectronics, Large Hermetic Modules, Metals, Ceramics, Telecommunications, Food, Medical Devices, Pharmaceutical, Packaging and Illumination.
The gas content inside sealed components, particularly moisture concentration, can cause long term reliability problems such as corrosion, fogging, leakage, current bit errors and lubrication issues. Known to some as Residual Gas Analysis (RGA) or "Mil-Std 1018", the test measures the primary sealing gases and trace gases. It is ideally suited for process development, sealing quality control, studying long term out-gassing of the enclosed materials inside the components, and for product qualification.
Both systems were designed and manufactured by ORS. Please view our IVA™ Instrument Sales web page for more information on acquiring this technology for use in your facility.
In parallel with Internal Vapor Analysis, ORS offers additional analytical techniques for the Qualification and process development of polymers, epoxies, coatings, and adhesives used in passive or active components. Outgassing of solvents, extenders, or reaction by-products and their deposition on critical surfaces can be a reliability concern. Residual outgassing products can be monitored and quantified by the following methods: Internal Vapor Analysis, Static headspace analysis by GC/MS, and ampoule analysis.
Test Methods
MEL-1053: Internal Vapor Analysis - Commercial Practice
This test procedure is used for testing hermetic devices in accordance with ORS’ Commercial Practice for Internal Vapor Analysis .This test method extends the scope and capabilities of traditional Mil-Std-883 or 750, method 1018 analysis. It permits variations to the procedure and/or device test conditions to achieve the best test conditions for specific client applications. Client specific protocols may be established for maximum accuracy and sensitivity for product monitoring applications, process development, R&D, materials evaluations and failure analysis projects. The data is not subject to inclusion in the annual retention report to DLA and all records regarding these tests are confidential.
MEL-1018: Internal Water Vapor Content - DLA Suitability for Military Devices
This test procedure is used exclusively for testing hermetic devices in accordance with Mil-Std-883 or 750, method 1018, procedure 1 per the conditions of “Suitability” status granted by DLA Land and Maritime (DLA). No variations are permitted to this procedure or to the device test conditions. Furthermore, all tests performed per this procedure are subject to inclusion in the annual retention report to DLA and all records regarding these tests are subject to audit and inspection by the U.S. Government.
Including Observations on the Outgassing Characteristics of Materials:
Using the 22 to 1 oxygen/argon ratio, we can determine that the oxygen content has also decreased from an expected 20.3% to a reported 15.6%. In this particular case, it was determined that a new lot of ceramic lids had a hydrocarbon residue that was thermally degrading during the sealing process, consuming oxygen and generating carbon dioxide and moisture in the process. The contaminant may have been from the manufacturing operation (e.g., a mold release agent) or from the packaging used in ship-ping (e.g., a residual plasticizer). The device manufacturer's usual cleaning process was insufficient to remove the contaminant.
