  • Patent number: 8591692
    Abstract: A method for manufacturing a rigid-flexible printed circuit board includes certain steps. A flexible substrate including an exposed portion and an attaching portion is provided. An adhesive sheet defining an opening, and a rigid copper clad laminate are provided. The rigid copper clad laminate includes an insulating layer and a copper layer. A blind first slit is defined in the insulating layer. The flexible substrate, the adhesive sheet and the copper clad laminate are laminated. An outer circuit is formed in the copper layer. A second slit is defined in the copper clad laminate, and the second slit is in communication with the first slit. A portion of the copper clad laminate is removed to expose the flexible portion of the flexible substrate.

  • 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.

  • Patent number: 8372824
    Abstract: Compounds exhibiting 3alpha-hydroxy-5alpha/beta-steroid blocking action with no or only low antagonism against the gamma-aminobutyric acid (A) receptor (GABA-A), and compounds exhibiting partial antagonism against said receptor are presented. Methods for the prevention, treatment and/or alleviation of various CNS-disorders are suggested, as well as pharmaceutical compositions for such use.

  • Patent number: 8308893
    Abstract: A method of increasing adhesion between a copper or copper alloy layer and a polymeric resin. The method includes the steps of a) applying a pre-dip composition to the copper layer; b) applying a nano-oxide composition to the treated copper layer, c) applying a post-dip composition to the nano-oxide treated surface, and d) bonding a resin to the treated copper surface. The nano-oxide composition comprises (i) a chlorite; (ii) a caustic; (iii) a phosphate salt; (iv) an organic nitro compound; and (v) a thio compound. The post-dip composition is an alkaline solution that comprises (i) a phosphate salt; (ii) a source of molybdenum ions; and (iii) a thiazole. The process of the invention is useful for improving the bond between copper and a resin, including high Tg resins, halogen-free resins, and high speed/lost resins.

  • Patent number: 8119619
    Abstract: Steroid compounds possessing a hydrogen donor in 3beta position, either in the form of a hydroxy- or a sulfate group, function as efficient blockers of the 3alpha-hydroxy-pregnan-steroid action and thus have utility as therapeutic substances for the prevention and/or treatment of steroid related CNS disorders. Treatment methods based on the administration of these substances are disclosed, and these substances either alone or in combination are also suggested for the manufacture of pharmaceuticals for the treatment of many specific steroid induced CNS disorders.

  • Patent number: 7645393
    Abstract: A process is described for treating metal surfaces with roughening compositions that use poly(ethyleneamino propionitrile) polymer as an additive in the composition to improve adhesion of polymeric materials to the metal surfaces and to improve peel strength for thermal stability. The polymer of the invention may be added to compositions containing for example, cupric chloride and hydrochloric acid and is also usable in compositions containing an oxidizer/acid/azole mixture. Other additives, such as adiponitrile may also be beneficially added to compositions of the invention.
