A quantitative technique to analyze materials trade-off for SEM `E´

The standard electronic module (SEM) is defined by a Department of Defense specification designed to optimize electronic module materials and designs for the military, as well as to reduce system life cycle cost through standardization of design and test requirements. The size of the module is defined by its format designation. For example, the E format specifies a substrate dimension of 133 mm (5.25 in) by 152.4 mm (6 in). However, the specification does not define the materials composing the substrate, leaving material specification to the module designer. The performance requirements for SEM E are evaluated using a technique called multiattribute utility analysis (MAUA). This technique has been employed in a wide range of engineering problems in general, and materials specification problems in particular, and its application to this problem yields rich insights into the critical elements of materials selection for the SEM E application
