Moiré interferometry is employed to test electronic control units, which are developed for automotive application utilizing transfer molding technology. The control units are subjected to a thermal cycle, and the two orthogonal in-plane displacement fields of the package cross-section are obtained at various temperatures. The results are used to(More)
The effects of the outer EMC on the thermal deformation of an automotive electronic control unit (ECU) are studied using moiré interferometry and FEA modeling. Two sets of ECU specimens molded with and without outer EMC are subjected to passive and active thermal conditions, respectively. Two orthogonal in-plane displacement fields on the cross(More)
In this study, we firstly report that hydrophilic graphite nanoparticles were successfully synthesized by liquid phase pulsed laser ablation method and the carbon-polymer composite sensor prepared with the nanoparticles showed a markedly enhanced gas sensing performance. The pulsed laser ablation of graphite rod in water generated well dispersed hydrophilic(More)
A hybrid experimental/numerical method is proposed for predicting the junction temperature distribution in a high-power laser diode (LD) bar with multiple emitters. A commercial water-cooled LD bar with multiple emitters is used to illustrate and validate the proposed method. A unique experimental setup is developed and implemented first to measure the(More)
