Abstract
In order to realize a micro mechanical relay, a new technology of adjusting the characteristics of relays by laser has been developed. While IT-related mechanical relays have been increasingly miniaturized, the mechanical adjustment system by using the conventional spring material bending has already come to its limit in the adjustment process of relays. In attempt to overcome this situation, the application of laser forming, which is able to deal with miniaturization and is not influenced by spring back, was examined. However, as the beam spring used for relays involves a thin thickness and high thermal conductivity, the conventional technique of repeating laser irradiation, which induces damage of the surface and residual stress, to the same parts couldn’t adjust the displacement with accuracy. A technique that changes beam path in repeating laser irradiations was then applied. Consequently, with a minimal number of times of irradiation, the characteristics of relays can be adjusted by using laser without causing damage to the surface.
