We reported the material properties, that we use in the numerical analysis, controls the quality of the analysis result directly in our previous paper. In this paper, we focus on the optimization of underfill for the high density packaging such as consumer electronics devices. We report the methodology to optimize the underfill properties through some parameter studies with numerical analysis. It...
We have obtained Eu2+-doped glass-ceramic phosphors, where the two-phosphor crystals of green and red were precipitated by novel GC preparation "frozen sorbet" method and postceraming process. The as-made GC consisted of glass and spherical beta-Ca2SiO4:Eu2+ crystal phases with size of about 20-40 mum. After ceramization, Ca3Si2O7:Eu2+ crystals were also precipitated in addition to the beta-Ca...
The POP (Package on Package) has been the core technology for high density package in the area of electronics devices, such as Mobile Phone, Digital Camera, Digital Video Camera and Notebook PC. And its utilization has been increased rapidly. The development of the new technology POP has been expected and the most focused concern is the reliability of it. In this paper, the reliance of the material...
