AmberClean™ 558 is a unique, high purity blend of nonionic surfactants designed to remove process residues and particulate contaminates from the surface of sensitive microelectronic components. It is recommended for use in highly technical, aqueous cleaning processes such as those encountered in the fabrication of thin film, MR and GMR heads. AmberClean 558 contains almost no anion and cation contaminants, and will not leave residues or films. It is formulated to be non-aggressive toward exotic metal alloys.
