The requirements for wafer-level packaging (WLP) are becoming more and stringent both from a sustainability perspective process performance. For instance, there is demand continuous improvement within die uniformity (WID) operating in low acid environment copper pillar plating. Antagonistic these requests are; however, we must devise novel ECP techniques additive designs to meet such ambitious ...

Bentonite bleaching earth is utilized for purifying used motor oil through a recovery process in order to improve the quality and stability of the final product. Indeed, spent bleaching earth is generated due to adsorbing oil impurities. Polluted spent bleaching earth contains 20-40% (w/w) oil and is flammable. Its disposal without pre-treatment leads to loss of oil along with environmental imp...

Abstract There are many models in the current statistical literature for making inferences based on samples selected from a finite population. Parametric may be problematic because inference is sensitive to parametric assumptions. The Dirichlet process (DP) prior very flexible and determines complexity of model. It indexed by two hyper-parameters: baseline distribution concentration parameter. ...
