PRODUCTION METHOD FOR SILVER-PLATED MATERIAL, SILVER-COATED SHEET METAL, AND CONDUCTIVE COMPONENT
[Problem] To provide a silver-plated material that not only has excellent wear resistance but can also keep the peeling resistance of a silver coating layer high, even when exposed to high-temperature/high-humidity environments. [Solution] According to the present invention, a production method for a silver-plated material includes an electro silver plating step for forming a silver coating layer on a base material by means of an electroplating method that uses a cyanide-containing silver plating liquid in which a benzothiazole or a derivative of a benzothiazole has been dissolved and a heat treatment step for holding the silver coating layer at a temperature of 150°C–300°C for 3–30 seconds. Mercaptobenzothiazole or a derivative of mercaptobenzothiazole can, for example, be used as the benzothiazole or the derivative of a benzothiazole.
The present invention provides: a silver-plated material wherein a silver plating film is not easily separated from a base plating film and exhibits excellent adhesion in a high-temperature high-humidity environment in cases where the silver plating film is formed on a base material with the base plating film being interposed therebetween; and a method for producing this silver-plated material. According to the present invention, after forming a base silver plating film (which preferably has a thickness of 0.06-15 µm) on a base material (which is preferably formed of copper or a copper alloy) with a base plating film (which is preferably formed of copper, nickel or an alloy of these metals) being interposed therebetween, a surface layer (a silver plating film containing carbon and sulfur) which is formed of silver and contains carbon and sulfur (the surface layer preferably having a thickness of 0.1-2.0 µm) is formed on the base silver plating film by performing electroplating in a silver plating solution which is composed of an aqueous solution that contains silver potassium cyanide or silver cyanide, potassium cyanide or sodium cyanide, and a benzothiazole or a derivative thereof.
An insulating substrate in which one principal surface of a heat-dissipation-side metal plate is bonded to one principal surface of a ceramic substrate via a brazing material layer provided therebetween, and a solder resist portion is formed on at least one selected from a periphery of the other principal surface of the heat-dissipation-side metal plate, a side surface of the heat-dissipation-side metal plate, and a surface of the brazing material layer. A solder resist prevents solder from wrapping around the brazing material layer, and thereby, what is called “the brazing material layer leaching into solder” no longer occurs and the occurrence of cracks inside the brazing material layer is avoided. This prevents stress concentration from occurring in the ceramic substrate at an inner portion relative to an end portion of the heat-dissipation-side metal plate.

METHOD FOR PRODUCING ALN SINGLE CRYSTALS, ALN SINGLE CRYSTALS, AND DEVICE FOR PRODUCING ALN SINGLE CRYSTALS
Provided are: a method for producing AlN single crystals, the method capable of producing AIN single crystals at low cost and in a continuous manner; AlN single crystals; and a device for producing AlN single crystals. The method for produing AlN single crystals includes: a melt formation step for heating and melting an alloy containing Al to form a melt of the alloy; and a deposition step for depositing AlN single crystals while providing a temperature gradient to the melt by cooling a part of the melt. In the deposition step, by bringing a nitrogen-containing gas into contact with a high-temperature section of the melt and holding AlN seed crystals or a crystal growth substrate for single crystals in a low-temperature section in the melt, with nitrogen being taken into the melt in the high-temperature section, AlN single crystals are deposited on the AlN seed crystals or on the substrate in the low-temperature section, and thereby AlN single crystals continuously grow.

MASK MEMBER FOR PARTIAL PLATING AND PARTIAL PLATING METHOD
Provided are a mask member for partial plating and a technique related thereto. The mask member comprises: a drum-type jig 11 including a jig opening disposition region 17 which includes a jig opening 13 for communicating a side surface inner side and a side surface outer side 16 of the drum-type jig 11 and which is a recess provided in a band shape running along the circumferential direction with respect to the side surface outer side 16; and a mask 31 which fills the jig opening disposition region 17 and includes a mask opening 32 at a site corresponding to the jig opening 13. The mask 31 is disposed in the jig opening disposition region 17, a through hole constituted by the jig opening 13 and the mask opening 32 is included, and an edge 33 of the mask opening 32 is raised toward the outer side direction of the drum-type jig 11.
An insulating substrate in which one principal surface of a heat-dissipation-side metal plate is brazed to one principal surface of a ceramic substrate via a brazing material layer provided therebetween, in which a Ni plating layer that covers the brazing material layer exposed between the ceramic substrate and the heat-dissipation-side metal plate is provided, and at least a portion of the other principal surface of the heat-dissipation-side metal plate is not covered with a Ni plating layer, leaving the surface of the heat-dissipation-side metal plate exposed. According to the present invention, it becomes possible to obtain the insulating substrate having excellent furnace passing resistance of the insulating substrate (alone) and further having excellent heat cycle characteristics in a state of a heat sink plate being soldered to the insulating substrate.
[Problem] To provide a silver-plated material which has excellent abrasion resistance and has the ability to maintain high resistance to peeling of a silver coating layer even when exposed to high-temperature and high-humidity environments. [Solution] The problem is solved by a silver-plated material production method wherein when forming a silver plating layer on a raw material via an electroplating method that uses a cyan-containing silver-plating solution, used as the silver-plating solution is an aqueous solution in which a selenium-containing substance and a benzothiazole or a derivative thereof are dissolved, in which the selenium concentration is 0.9-120 mg/L, and in which the molar ratio of the selenium to the benzothiazole or the derivative thereof is not less than 0.08×10-3. Mercaptobenzothiazole or a derivative thereof, for example, may be used as a substance corresponding to the benzothiazole or the derivative thereof.
