  • Acid-resistance promoting composition
    Patent number: 8518281
    Abstract: A composition for providing acid resistance to copper surfaces in the production of multilayered printed circuit boards. The composition comprises an acid, an oxidizer, a five-membered heterocyclic compound and a thiophosphate or a phosphorous sulfide compound. In a preferred embodiment, the phosphorous compound is phosphorus pentasulfide. The composition is applied to a copper or copper alloy substrate and the copper substrate is thereafter bonded to a polymeric material.
    Type: Grant
    Filed: June 3, 2008
    Date of Patent: August 27, 2013
    Inventors: Kesheng Feng, Ming De Wang, Colleen Mckirryher, Steven A. Castaldi
  • Process for improving the adhesion of polymeric materials to metal surfaces
    Patent number: 8088246
    Abstract: An adhesion promoting composition and a process for treating metal surfaces with the adhesion promoting composition is described. The adhesion promoting composition comprises an oxidizer, an acid, a corrosion inhibitor, a source of halide ions and a material selected from a mercapto propane sulfonate, mercapto propane sulfonic acid, and bis-sodium sulfopropyl disulfide. The adhesion promoting composition increases the adhesion of polymeric materials to the metal surfaces and also provides increased acid resistance.

  • Method for enhancing the solderability of a surface
    Patent number: 7631798
    Abstract: A method for enhancing the solderability of a metallic surface is disclosed where the metallic surface is plated with a silver plate prior to soldering, which immersion silver plate is treated with an additive comprising a mercapto substituted or thio substituted silane compound. Preferred post treatments comprise 3-mercapto propyl trimethoxysilane and/or 3-oxtanoylthio-1-propyltriethoxy silane.
