In our company the materials science department is a tool to check the quality of the products ( here electoplated metal layers like copper, nickel, gold, silver, chromium and others on glas and resin materials.) and to investigate failures on the products. For this different methods are used, like simple micro section of sample parts and check by light microscope, SEM and EDX analysis. Newest tool is FIB Focus ion beam to investigate structures of metals and failures on it.
