Abstract
PURPOSE:To stabilize the contact resistance at a low contact pressure by specifying the particle diameter of an alloy layer formed by the diffusion of tin atoms in a coating layer and copper atoms in a basic material or in a foundation at the interface between a pure tin layer or a tin-lead alloy layer in the heating and melting condition. CONSTITUTION:The mean particle diameter of an alloy layer formed by the diffusion of the tin atoms in a coating layer and the copper atoms in a basic material or in a foundation in a heating and melting condition, at the interface between a pure tin layer or a tin-lead alloy layer is made 1 to 5mum. This copper- tin alloy layer is exposed by removing the tin layer or the tin-lead alloy layer when the coating surface is treated by an electrolytic grinding or by using an alkaline chemical grinding liquid. The exposed copper-tin alloy layer, that is, Cu6Sn5 phase or Cu3Sn phase, is granular and numerous microscopic contacts are formed at the contacting time. In such a way, a stable material with a low contact resistance can be obtained.
