Electronics

Surface Science Western has worked with manufacturers of electronic devices from Canada, The United State and Asia. Much of our work has involved identifying residues and contaminants associated with the fabrication of microchips, photomasks and silicon wafers. We have also helped assemblers with quality control issues by examining defective solder joints, residue and contamination on circuit boards and addressed concerns with regard to lead content.

Companies that are active in research and development have also benefited from SSW’s expertise, including improving flat panel displays and evaluating prototype devices.
