Abstract:
A bonding wire comprising a core mainly consisting of copper, a different metal layer formed of a metal other than copper and formed on the core, and a coating layer formed of an oxidation-resistant metal having a melting point higher than that of copper and formed on the different metal layer, from which balls having the shape of a true sphere in a wide ball diameter range can be formed stably, which can be produced without causing the deterioration of a plating solution at the time of plating, and in which the adhesiveness between the coating layer and the core thereof is excellent; and an integrated circuit device using the bonding wire are provided.
Abstract:
A coated optical fiber unit having at least two coated optical fibers, each of which has a coloring layer as the outermost layer and which are coated together with a bundling coating layer, is disclosed. The bundling coating layer and the coloring layer are both treated to suppress their bonding, there by allowing the coloring layer to not be removed at the same time as the removal of the bundling coating layer. The releasing agent added to the bundling coating layer and the coloring layer does not swell the resins in the layers, or cause peeling of the protective coating layer from the optical fiber.
Abstract:
A coated optical fiber includes an optical fiber, a primary coating layer disposed on the optical fiber, and a colored layer provided on the primary coating layer. Ink used in the colored layer has small change of weight due to immersion into water or a sensitizer in the ink has small solubility to water.
