Glass Lead Seal Test Apparatus.
Abstract
Glass lead seal test apparatus in which a multiplicity of microcircuit packages with the leads sealed relative thereto by glass are checked for leakage between the glass seals and the microcircuit package structure and relative to the leads; this is accomplished by providing an apparatus for evacuating a chamber of the microcircuit packages and a chamber of the apparatus, and then injecting helium into the chamber of the apparatus and then utilizing test structure to test leakage around the glass seals if a perfect seal is not present. The device is designed to handle a multiplicity of microcircuit packages during a given test cycle. (Author)
