    Applicant: Siemens Industry, Inc.
    Inventor: Karl F. Seelig
  • Publication number: 20100059576
    Abstract: A lead-free and solder alloy composition for electronic assembly applications having reduced toxicity. The alloy composition comprises, by weight, about 0.2% to about 1% copper; about 0.001% to about 0.039% nickel; about 0.001% to about 0.039% cobalt; and the balance of tin. The alloy composition has a melting temperature of about 227° C., with superior wetting and mechanical strength making the alloy composition wells suited for electronic circuit board manufacture and lead less component bumping or column arrays, and replacement of conventional tin-lead solders.

  • Patent number: 5405577
    Abstract: A lead-free and bismuth-free solder alloy composition for electronic assembly applications having reduced toxicity. The alloy composition consists of, in weight percent, 90.3-99.2% tin, 0.5-3.5% silver, 0.1-2.8% copper, and 0.2-2.0% antimony. The alloy composition has a melting temperature of 210.degree.-216.degree. C. with superior wetting and mechanical strength making the alloy composition well suited for electronic circuit board manufacture and replacement of conventional tin-lead solders.
