The software architecture of smart learning environment can be perceived as an environment that is equipped with various audio-visual objects to capture human motion, utterance and gesture, allowing the teacher to deliver lectures to both local and remote audience through the Internet. The interactive objects in such architectural environment are interfaced with simple navigation, depending on operation...
Die attach material (DA) is important to heat dissipation and light output of solid state lighting (SSL) packages. Even though high thermal conductivity benefits to reduce the bulk thermal resistance of die attach, high viscosity will increase the contact thermal resistance in the packages. To face such a dilemma, it is of desirable to develop new technique to increase the filler loading without sacrificing...
The mechanism of thermal conductivity enhancement of silver epoxy based die attach materials (DA) by iodine treatment is studied. Iodine treatment is found to be able to uniform the polymer network and accelerate the curing of die attach at relatively lower temperature with shorter curing duration. In addition, several metal halide salts are proved to have the same effect as the iodine treatment and...
