The layer of clients in e-business network environment tends to produce demand fluctuation, here in consideration of the poorest demand fluctuations at the layer of clients under general conditions,...
In present study, an interesting phenomenon of solder bridging presents in fine pitch BGA device is reported. The failure mechanism is investigated by solder formation modeling, and examined by experimental results of multi-factors evaluation. Results show that the risk of adjacent joints bridging is highly influenced by printed circuit board design attribute. A mathematic model is applied to describe...

In order to further empirical study of the performance of structural models in China, this paper empirically tests four structural models of corporate bonds pricing: those of Merton (1974), modified Merton with exogenous recovery rate, Black and Cox (1976) and Leland and Toft (1996). The article implement these models by using a sample of 45 Chinese firms issuing short-term financing bonds in 2006...
