    • A process for producing a printed circuit board, which comprises the steps of forming a layer comprising a photosensitive resin composition on an insulating substrate having on its surface an adhesive layer adherent to a metal being subsequently plated thereon; exposing said layer comprising a photosensitive resin composition to an actinic radiation in a manner so as to form on said layer a negative pattern of a conductor circuit pattern and to semicure said negative pattern to an extent sufficient to keep it from erosion by a plating solution; developing by dissolving away with a solvent the uncured areas not exposed to said actinic radiation, thereby to form a plating resist on the areas of said negative pattern; chemically plating said conductor circuit pattern areas not covered with said plating resist, thereby to form a conductor circuit; and carrying out a curing treatment to cure completely said resist. According to this invention, it is possible to provide a printed circuit board of higher reliability compared with conventional processes.
    • 一种制造印刷电路板的方法,包括以下步骤:在绝缘基材上形成包含感光性树脂组合物的层,其表面上附着有金属的粘合剂层,随后在其上镀覆; 将包含光敏树脂组合物的所述层以使其在所述层上形成导体电路图案的负型图案并将所述负型图案半形成足以使其免受电镀溶液侵蚀的程度使光敏树脂组合物暴露于光化辐射; 通过用溶剂除去未暴露于所述光化辐射的未固化区域,从而在所述负型图案的区域上形成电镀抗蚀剂; 对未被所述电镀抗蚀剂覆盖的所述导体电路图案化学电镀,从而形成导体电路; 并进行固化处理以完全固化所述抗蚀剂。 根据本发明,与传统工艺相比,可以提供具有更高可靠性的印刷电路板。
