IPC: H01K1/20
Filed: 1986-02-07
Abstract: PURPOSE:To obtain a Dumet wire in which a brazing material is not molten again and a defect such as the minute swelling of a coating copper layer is not caused when a proper cuprous oxide layer is made at 950 deg.C or above, by providing an iron-nickel alloy core wire, a brazing material layer having a prescribed composition and made on the peripheral surface of the iron-nickel core wire, and the coating copper layer made on the peripheral surface of the brazing material layer. CONSTITUTION:An iron-nickel alloy core wire, a brazing material layer and a coating copper layer are provided. The brazing material layer is made on the peripheral surface of the iron-nickel alloy core wire and comprises 72.0 to 90.0% by weight of copper and the rest of zinc. The coating copper layer is made on the peripheral surface of the brazing material layer. A small amount of an element such as Si, Mn and Al may be added to the brazing material layer to adjust the flowing property, corrosion resistance and so forth thereof. If the amount of the copper of a copper-zinc alloy constituting th brazing material layer is less than 72.0% by weight, the brazing material layer is likely to be molten again due to heating for making a proper cuprous oxide layer containing no cupric oxide. If the amount of the copper of the copper-zinc alloy is more than 90.0% by weight, it is difficult to put the brazing material layer in completely tight contact with the iron-nickel alloy core wire and the coating copper layer.

IPC: G06K19/077
Filed: 1988-02-05
Abstract: PURPOSE:To reduce the warping in the part of an electrode terminal, by orienting the glass fibers of a glass fabric substrate into the same direction so that the coefficient of thermal expansion of an electrode terminal substrate and that of a substrate for mounting parts thereon are approximate to each other. CONSTITUTION:When a flat substrate 1 for an electrode terminal is bonded to a flat substrate 2 for mounting parts thereon, the temperature is raised by  T from the initial temperature T for soldering. However, as the temperature falls, warpings may be generated in some cases. Therefore, in the case where the substrates are glass fabric epoxy substrates, such substrates 1, 2 that have glass fibers 10 oriented to the same direction, that is, to the direction in which the flatness is most important, are employed in order to make the coefficient alpha1x of thermal expansion in the lateral direction of the substrate 1 approximately equal to the coefficient alpha2x of the substrate 2 since the coefficient of thermal expansion differs in accordance with the directional properties of the glass fibers 10. In this case, for the substrate 1, the coefficient of thermal expansion in the longitudinal and lateral directions is set to be alpha1x<alpha1y. Thus, the generation of warpings can be reduced in the part of the electrode terminal.
