Thermal analysis of power hybrid microelectronic packages
In this dissertation a simplified nondimensional approach for the thermal analysis of power hybrid circuits is presented. The new technique uses only the metallization and the substrate as layers and represents everything below the substrate by an external thermal resistance (expressed as an …

Modeling and simulation of surface mount packages
… and performance evaluation of plastic packages for surface mount devices. Of particular interest in this work are packages for use in the gigahertz range. In order to accurately model these packages, time and frequency domain measurements of two different packaged structures are …

Assembly Yield Model for Area Array Packages
… assembly process. Assembly yields of area array packages are heavily dependent on design of the board as much as package and process parameters. The economics of IC technology is such that the maximization of yield rather than the optimization of performance has become the topic of prime …

Analysis of column interconnects for wafer level packages
… Copper column (CuC) interconnect for wafer level packages. First, a simulation-based design optimization process was established based on ABAQUS and Minitab. This process integrated finite element simulation, design of experiment and numerical optimization, generating a systematic and efficient …

HYGROTHERMALLY-INDUCED DELAMINATION AND CRACKING IN PLASTIC IC PACKAGES
Plastic-encapsulated packages are susceptible to moisture-induced cracking due to high moisture permeability of the typical epoxy molding compound. During solder reflow, the high temperature together with the previously absorbed moisture will result in high hygrothermal stresses at material …

The Emotional Effects of Warning Labels on Nicotine Pouch Packages
The aim of the study was to measure the emotional effects of warning images on nicotine pouches containers on users and non-users of nicotine pouches. If applicable, similar warning images might be used to affect people’s consumption of nicotine pouches. Participants observed five sets of warning …
