Abstract:

This is the first of two volumes. The other volume WL-TR-91-3119 is Fracture Mechanics. The objective of the Electronics Reliability Fracture Mechanics ERFM program was to develop and demonstrate a life prediction technique for electronic assemblies, when subjected to environmental stress of vibration and thermal cycling, based upon the mechanical properties of the materials and packaging configurations which make up an electronic system. A detailed investigation was performed of the following two shop replaceable units SRUs Timing and Control Module PN 3562102 and Linear Regulator Module PN 3569800. The SRUs are in the Programmable Signal Processor 3137042 Line Replaceable Unit LRU of the Hughes ANAPG-63 Radar for the F-15 Aircraft.
