Interfacial impedance method was applied to evaluate the interface stability of solder joints. Results showed that the surface treatment on rolled copper strongly influenced the solder joint interface structure. The composition and interfacial impedance between rolled copper and solder were also influenced by the surface treatment of the copper. Especially, a correlation was found between the surface treatment and time dependence of the interfacial impedance value. The admittance spectra of interfacial impedance between as-rolled copper and solder showed strain from the semicircular shape, although the plasma ashed copper or thermally oxidized copper showed no such strain over time. The strain probably represents solder joint instability. The interfacial impedance method can be useful for evaluation of the solid metal interface, not only the interface between the liquid and solid.

Electrolyzed alkaline water, obtained by the electrolysis of a dilute NaCl solution in a cathode compartment shows high pH (alkalinity), low ORP (Oxidation Reduction Potential), and moderate reducibility and oil-emulsification. By utilizing the characteristics of the alkalinity and the oil-emulsification of the electrolyzed alkaline water, metals and lead frames stamped with oil were washed and cleaned, then the cleanness of metals and lead frames for electronic products was evaluated. The surface analysis and quantitative data on remaining residual oils and ionic contamination, AES (Auger Electron Spectroscopy) analysis on metals, and wire-bond pull strength on the lead frames which were washed and cleaned by the electrolyzed alkaline water, showed the same level of cleanness compared to that of the conventional cleaning method by chemicals.

Chemical polishing solutions for aluminum based on mixtures of phosphoric and nitric acid cause air pollution with hazardous gaseous emissions, such as NOx, during the chemical polishing process, and cause water pollution due to the effluent of wastewater that contains phosphates and nitrates. Hence, the authors attempted to polish aluminum in an alkaline solution containing sodium hydroxide as an alkaline agent and sodium persulfate as an oxidizing agent. In this process, exceptionally bright surfaces of aluminum were obtained; that is, the brightness of the surface polished in the alkaline solution was comparable with that of the surface polished in an acid chemical polishing solution. The composition of the alkaline solution that had the least polishing effect had a concentration of sodium hydroxide in a range of 0.5 to 1.5% by weight for pure aluminum and a range of 1.0 to 2.0% by weight for commercially pure aluminum, while the concentration of sodium persulfate was 35% by weight. At with a high magnification on a scanning electron microscope (SEM), network patterns were observed over the entire polished surface of the aluminum polished in the alkaline solution and that in the acid chemical polishing solution. On the surface of the commercially pure aluminum polished in the alkaline solution, very small projections were observed by SEM, that were identified by electron probe microanalysis (EPMA) as insoluble phases that included foreign elements such as Fe and Si in the aluminum. On the other hand, on the surface of the aluminum polished in the acid chemical polishing solution, very small pits were observed, formed by dissolution of the phases in the acid solution. Also, use of x-ray photoelectron spectroscopy (XPS) and fourier transform infrared spectroscopy (FT-IR) indicated that the oxide films formed on the surface of the aluminum polished in the alkaline solution were thicker and contained a larger amount of hydroxyl radicals than those on the surface polished in the acid chemical solution.
