Tin plated surface used for contact surface such as connectors is usually covered with the oxide vfilm in the atmosphere. As the surface covered with the film, surfcae corrosion is prevented from gas in the atmosphere, the surface has corrosion resistance characteristic. However, the oxide film is interposed between contact interfaces, contact resistance increase extremely in low contact load. therefore, the problem of contact reliability is exist. In previous study, the growth law of tin oxide film was already clarified. namely, the oxide film thickness saturated about 10nm at room temperature. At elevated temperature (80-120 centigrade degree), thr growth law indicated same tendency as at low temperature. In this study, growth law at the temperature of 150 degree was studied, and it was found that the growth law was different from that of low temperature. The cause is found in change of optical constants of the surface. This should be dependence of formation of the film. The film formation is amorphous SnO at temperature between romm temperature to 80 degree. However, at 120 degree, the formation changed to crystallized SnO2. Moreover, for 150 degree, the crystallization is much more remarkable. |
