摘要

The long-term reliability of surface mount (SM) interconnectionsremains an important issue in many electronics packaging technologies.Strain-reliefs with sufficient compliance can minimize the cyclic loadsimpressed on SM solder connections during operational temperatureexcursions, appreciably increasing the margin for long-term attachmentreliability. Compliance evaluation was performed for an inter-boardstrain-relief, or bond-strap, in a commercial Low-Noise Amplifier (LNA)used in various AT&T wireless transmission systems. The bond-strapcompliance was optimized, within practical forming and assemblyconstraints, to provide robust SM interconnection during the expectedproduct service life

7. ABSTRACTudThe purpose of this research is to obtain an optimal formulations of Black mulberry leaves dried noodle product by using Design Expert Application with Design Mixture D-optimal method.udThis research was done with two phases. The preliminary procedures research is to determine levels of antioxidant activity, chlorophyll content, and the levels of tannin that was contained in black mulberry leaves, the black mulberry leaf flour, a pare fruits, and pare flour. Primary research is to determine the best formulation by using a Mixture Design Expert Design D-optimal method, for a purpose is to optimized the Black mulberry leaf dry noodle. Responses in this studies are a chemical analysis response by using a crude fiber analysis and protein analysis. Physical response is water absorption. Sensory response are color, flavor, and odor.udBlack mulberry leaves dried noodles was made from wheat flour, black mulberry leaf flour, and pare flour, other materials such as an eggs, water, salt, and sodium bicarbonate, of the 16 formulations that has offered to produce an optimal formulation based on desirability which contains 39.69 Flour,14.25 Black Mulberry Leaves flour, 3.06 Pare fruit and flour amounted, and other materials are 30 water, 10 eggs, 2 salt, and 1 sodium bicarbonate. The formulation has been result by program 11,05 crude fiber content, 12.93 protein, 274.31 water absorption, 4,31 for color attribute, 3,87 for taste attribute, and 3,71 for aroma attribute.ududKeyword: Black mulberry leaf dried noodles, optimization.
