The main vehicle for testing of high reliability flatpack packages has been MIL-PRF-38534 (General Specification for Hybrid Microcircuits). This document outlines the general requirements of fully assembled devices, whether they are single chip, multichip, or of hybrid technology. The test procedures of these requirements are found in MIL-STD-883 (Test Methods and Procedures for Microelectronics) as a listing of test methods. These methods cover various aspects of the minimum requirements that a microelectronics device must be able to attain before it is considered a compliant device.
