Process Elemental Analysis by EDXRF of Chemical Bath for Copper Foil Surface Treatment

Rigaku Corporation
30 Apr 2013

Surface treating is an important part in the manufacture of copper foil for the electronics industry. Surface treatments are used to clean the copper foil, to create roughing and heat resistance treatments, and to make single or multiple layer thin film coatings to prevent oxidation or enhance the electro-chemical properties of the copper foil. The chemical baths must be constantly monitored to ensure the highest quality surface treatments. This application note demonstrates how the NEX OL analyzer can meet the analytical needs for trend analysis of bath composition.

X-Ray Diffraction and SpectroscopyX-Ray diffraction & spectroscopy are used in material characterization to discern the structure and elemental composition of a sample. X-Ray diffractometers (XRD) are superior instruments in elucidating the dimensional atomic structure of crystalline materials, including powders, thin films and single crystals. For large unit cells or ordered macromolecules, consider small-angle X-ray scattering (SAXS). X-ray spectroscopic techniques include X-ray fluorescence (XRF) and X-ray photoelectron spectroscopy (XPS), both providing simple and accurate methods for determining the elemental composition of a material. Energy dispersive (EDXRF) and wavelength dispersive (WDXRF) XRF spectrometers are available, as well as handheld/portable devices. High-resolution, 3D microstructure characterization of materials can be achieved with X-ray microscopes combining sub-micron resolution imaging with 3D computed tomography. Find the best XRD and XRF spectrometers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.NickelProcess DevelopmentProcess development aims to optimize the performance of manufacturing systems. This involves the assessment of quality and efficiency of both processes and products. This is particularly important in the scale-up of chemical processes.
