  • Flux solution for soldering containing borneol
    Patent number: 6193812
    Abstract: A soldering flux containing borneol, which is also referred to as bornyl alcohol. A method soldering using such a flux is also disclosed. Even minor proportions of borneol in the flux help reduce ionic residue from the flux after soldering. Larger proportions of borneol can give the flux tackiness for wave soldering operations. The flux preferably comprises borneol and an organic acid activator that volatilizes during soldering. The flux is applied as a solution of borneol and the organic acid activator in a solvent that substantially evaporates before soldering without leaving any measurable solvent residue.
    Type: Grant
    Filed: November 8, 1999
    Date of Patent: February 27, 2001
    Assignee: Delco Electronics Corporation
    Inventors: Samuel Victor Bristol, Mary Beth Young, David Ross Summers

  • Coatings and methods, especially for circuit boards
    Patent number: 6066197
    Abstract: A coating composition for use in protecting metal, and for use as a soldering flux, and methods involving the same. A coating for circuit boards and processes involving the same. One coating material can serve as a metal corrosion inhibitor, a no-clean soldering flux, and/or a protective coating in replacement of a conformal coating. In its most preferred form, this invention serves all three functions in the manufacture of an electrical circuit board.
