    摘要: The present invention provides a method of performing high density over the edge circuitization on circuit cards. In particular, the invention allows for circuits having width and spacing requirements of one millimeter or less to be placed over the edge of a substrate. The method includes the steps of: (1) angling the substrate such that the first surface, second surface and edge separating the two surfaces form an exposed region; (2) metallically sputter seeding the exposed region from a seeding source such that a metallic sputter seed layer is formed; (3) covering the exposed region with a dielectric material; (4) ablating portions of the dielectric material; (5) applying a conductive layer, for example, with copper plating, on the circuit path to form a circuit; (6) removing the remaining unablated dielectric material, thereby exposing portions of the metallic sputter seed layer that are adjacent to the circuit; and (7) removing the exposed portions of the metallic sputter seed layer that are not part of the circuit.

    摘要: A pattern is provided on a substrate by providing the substrate with at least two layers of material thereon and providing a layer of dry imaging polymer compositions thereon. The layer of the dry imaging polymer composition is laser ablated to provide the desired personality pattern. The top exposed portion of at least the top layer is removed and the desired select pattern is laser ablated. The exposed portions of said first layer is removed and the pattern is completed through the other layers of material to thereby expose the substrate surface, without the substrate surface being subjected to laser ablating to thereby provide the desired pattern on the substrate.
