 Internal Water Vapor Content

 In order to eliminate failures in microelectronic components  caused by chemical reaction (corrosion), the internal gas  composition of the component must be known. MIL-STD-883,  Method 1018.5 is generally the accepted specification for  internal water vapor content. This method defines procedures  for RGA equipment calibration and device testing, as well as  the maximum acceptable limits for water vapor content.

RGA is useful for more than moisture content analysis. SEAL Laboratories' RGA system can detect all masses up to 100 AMU, allowing common gasses to be identified and quantified. Samples of process atmospheres and unusual sealing environments can be analyzed to detect the evolution or resorption of gasses. The system software can determine moisture content as well as an entire spectrum of gasses in the component.

In addition to providing routine RGA analysis, SEAL Laboratories staff has the technical expertise to identify the origin of the "problem" internal gasses and provide corrective action on an as-needed basis.

PACKAGES:
DIP's, Quad Packs, TO-x Cans, Metal Lidded Devices, Filler Gas Containers and many other geometries can be analyzed.

VOLUMES:
0.01cc to 25cc volumes can be analyzed. Precision radiographic and computer modeling techniques are used to determine the volume of a package

ANALYSIS:
All gases with molecular weights between 1-100 mass units can be identified with a survey scan, or up to 16 components can be preselected for quantitative analysis.

MIL-STD-883/750 TESTING:
Nitrogen, Oxygen, Argon, Carbon Dioxide, Moisture, Hydrogen, Helium, Fluorocarbons, Methane, and Ammonia are measured and reported.
