    摘要： The purpose of the present invention is to provide equipment for separating excess copper dissolved in a lead-free solder bath and recovering purified tin with high efficiency. An element X for forming a (CuX) 6 Sn 5 compound between copper and tin in molten lead-free solders is added in an precipitation container to separate out a (CuX) 6 Sn 5 compound. Tin is recovered by binding the (CuX) 6 Sn 5 compound by passing thereof through a multi-perforated plate in a granulation container, further generating swirling currents to precipitate and separate the bound (CuX) 6 Sn 5 compounds in a separation container and removing thereof.

    摘要： An apparatus for precipitating/separating excess copper which has dissolved in a lead-free solder comprising tin as the main ingredient. With the apparatus, the tin is safely and efficiently recovered. The apparatus (1) enables copper which has dissolved in a lead-free solder comprising tin as the main ingredient to precipitate as an intermetallic compound to separate the copper. It has a constitution comprising: a precipitation tank (2) in which a lead-free solder containing copper dissolving therein is kept in a molten state and an intermetallic compound among a metal added externally, the copper contained in the molten solder, and the tin contained in the molten solder is precipitated while maintaining the molten state; a granulation tank (4) which has perforated plates (31), (32), and (33) and in which the molten lead-free solder is passed through the perforated plates to thereby bond particles of the intermetallic compound to one another and increase the particle diameter thereof; and a separation tank (5) in which the enlarged intermetallic compound particles are sedimented in the molten lead-free solder and separated.

    摘要： A solder joint manufactured of an alloy essentially composed of 0.01-7.6 wt% Cu, 0.001-6 wt% Ni, and the remaining of Sn. Each of Cu and Ni has a maximum concentration range. The lower limit of the range of Ni is 0.01 wt% and preferably 0.03 wt%. The upper limit of the range of Ni is 0.3 wt% and preferably 0.1 wt%. The lower limit of the range of Cu is 0.1 wt% and preferably 0.2 wt%. The upper limit of the range of Cu is 7 wt% and preferably 0.92 wt%. The invention includes the solder joint essentially having these compositions.

    摘要： An apparatus for depositing and separating excess copper dissolved in molten lead-free solder containing tin as the main element is provided. An apparatus 1 deposits excess copper in the molten lead-free solder as an intermetallic compound and separates it from the molten solder. The apparatus includes a deposition bath 2 for causing an intermetallic compound in the molten solder, a metal added from the outside and copper in the molten solder to be deposited, a granulation bath 4 including plates 31 32 and 33 for allowing the molten solder to pass through the plates to merge the intermetallic compounds into particles having a larger diameter, and a separation bath 5 for causing the enlarged intermetallic compounds to precipitate and separate in the molten solder.
