Particle Size Distribution in Aluminum Manufacturing Facilities

Particle Size Distribution in Aluminum Manufacturing Facilities

As part of exposure assessment for an ongoing epidemiologic study of heart disease and fine particle exposures in aluminum industry, area particle samples were collected in production facilities to assess instrument reliability and particle size distribution at different process areas. Personal modular impactors (PMI) and Minimicro-orifice uniform deposition impactors (MiniMOUDI) were used. The...

Kernel-Density-Based Particle Defect Management for Semiconductor Manufacturing Facilities

In a semiconductor manufacturing process, defect cause analysis is a challenging task because the process includes consecutive fabrication phases involving numerous facilities. Recently, in accordance with the shrinking chip pitches, fabrication (FAB) processes require advanced facilities and designs for manufacturing microcircuits. However, the sizes of the particle defects remain constant, in...

Particle Size Distribution in Food Powders

Project: Controlling Particle Size and Particle Distribution in Crystalization Operations

Crystallization is a widely used technology for solid-liquid separation in the process industry. It is extensively used in the production of pharmaceuticals to separate the drug from the solvent mixture as well as to ensure that the drug crystal product conforms to size and morphology specifications. The crystal size in crystallization processes is one of the most important variables since it i...
