Abstract:
The purpose of the present invention is to improve processing performance in laser beam drilling a copper clad lam-inate board, a blackening treated surface of said copper clad laminate board being to be used as a treatment surface in the laser beam drilling. To achieve this purpose, a copper foil (1) with attached carrier foil is provided, said copper foil (1) with attached carrier foil having a layered structure consisting of a carrier foil (2)/a release layer (3)/a bulk copper layer (4) and being characterized in that metal component-containing grains (5) are disposed between the release layer (3) and the bulk copper layer (4). When a copper clad laminate board is manufactured by using this copper foil with attached carrier foil, a blackening treated layer with a color that ensures excellent laser beam drilling performance can be formed on the surface of the bulk copper layer.
Abstract:
A conductive polymer-metal complex becomes to be adhered simply and strongly on the surface of a substrate such as PTFE. By subjecting a solution containing a monomer which provides a conductive polymer, an anion, and a metal ions such as Ag + , Cu 2+ , Cu + and the like to an irradiation with light having an energy required for exciting an electron to an energy level capable of reducing the metal ion, such as ultraviolet light, under an appropriated condition, thereby precipitating the conductive polymer-metal complex as being dispersed in the reaction liquid. By supplying this dispersion liquid onto various substrates, the complex microparticles in the dispersion liquid enter into and mate with the narrow holes on the surface of the substrate. As a result, the complex precipitate formed on the surface of the substrate and the substrate can be adhered strongly to each other.
