... on solder joint stress. Optimization of assembly parameters was achieved through the application of the Taguchi method. An extensive analysis was conducted using different assembly parameter combinations, employing the L9(3 4 ) orthogonal array design to explore the thermal cycling effects. The computed...

... phosphor diameters, and using finned phosphor layers were considered as optimization measures to improve the heat dissipation performance of LED filament lamps. When these optimization measures are applied, chip junction temperatures are reduced. A reduction of 6.9 °C is seen when the lamp radius...

... to bring significant thermal challenges for 3D packages due to localized hot spots. Embedded thermoelectric coolers (TECs) have potential to provide reliable and localized cooling at these hot spots. In this work, peak package temperature or active cooling per power consumption of TECs are optimized...

..., x ¯ , of the multi-objective problem is either dominated or nondominated; all nondominated solutions are called Pareto-optimal solutions. The vector, x ¯ i , dominates a vector x ¯ j if x ¯ i is at least as good as x ¯ j...

...M. O. Özdemir; H. Yüncü The objective of this study is to predict numerically the optimal spacing between parallel heat generating boards. The isothermal boards are stacked in a fixed volume of electronic package enclosed by insulated lateral walls, and they are cooled by laminar forced convection...

...Hsien-Cheng Tseng Advanced collector-up (C-up) heterojunction bipolar transistors (HBTs) with the thermal-via configuration (TVC) have been analyzed using a genetic algorithm (GA). Novel packaging structures are presented and evaluated in detail. With careful optimization, the thermal performance...

...Afzal Husain; Kwang-Yong Kim A microchannel heat sink shape optimization has been performed using response surface approximation. Three design variables related to microchannel width, depth, and fin width are selected for optimization, and thermal resistance has been taken as objective function...

...Avram Bar-Cohen; Madhusudan Iyengar; Allan D. Kraus The effort described herein extends the use of least-material single rectangular plate-fin analysis to multiple fin arrays, using a composite Nusselt number correlation. The optimally spaced least-material array was also found to be the globally...
