The mixed solution is introduced into a reservoir of the organic fatty acid solution, and the purified molten tin solution or molten solder alloy liquid separated according to the specific gravity difference in the reservoir of the organic fatty acid solution is returned from the bottom of the organic fatty acid solution reservoir to the reservoir of the molten tin or molten solder liquid by a pump for circulation use. By means of this, copper is prevented from accumulating in the molten tin or molten solder liquid, and thus it is possible to continuously perform a stable soldering process for a long term.04-07-2011
20110089567Production Method and Production Apparatus of Tin or Solder Alloy for Electronic Components, and Solder Alloy - The invention provides a technique and a device that dramatically improve joint reliability of miniature joints of fine electronic components. According to the invention, when producing a tin or a solder alloy used for electronic components, an ingot of a tin or a solder alloy is heated, melted and delivered to a reactor. Also, a solution containing organic acid having a carboxyl group (—COOH) is delivered to the reactor. After stirring and mixing the two liquids intensively, the mixed liquid is separated into a molten tin or a molten solder alloy liquid and an organic acid solution according to the difference in specific gravity. Then, the respective liquids are circulated to the reactor, and the metal oxides and the impurities existing in the molten tin or the molten solder alloy are removed, and the molten tin or the molten alloy is purified to have oxygen concentration of 5 ppm or less.04-21-2011
