Abstract : Microelectronic packages with marginal glass-to-metal seals often escape detection at receiving inspection when they are tested by present methods for determining hermeticity. A more effective test method is desirable for fulfilling the requirement of effectively detecting marginal quality microelectronic package hermeticity. This final report describes the results of an extensive study of various dye penetrant materials and specially designed equipment in developing an optimum and effective liquid dye penetrant test method for determining the hermetic quality of various types of microelectronic packages.
