    • A method for manufacturing a fine-patterned thick film conductor structure free from ununiformity in film thickness comprises steps of forming resist on a thin metal plate at areas other than land areas, electroplating the thin metal plate using the thin metal plate as a cathode electrode to form conductors having a circuit density of no less than three lines/mm and a thickness of 15-200 .mu.m, bonding the electroplated thin metal plate to an insulative substrate with the thin metal plate side facing up and etching the thin metal plate. The fine-patterned conductors are suited for use in small-sized coils, high density connectors and high density wirings.Further disclosed is a method for manufacturing a fine-patterned thick film printed circuit board free from side protrusion comprising steps of forming resist on a thin metal plate at areas other than land areas, electroplating the thin metal plate to a thickness of 0.3-10 .mu.m at a current density of 0.05-2 A/dm.sup.2, electroplating the thin metal plate to a desired final thickness at a current density of 3-20 A/dm.sup.2, and removing all or the areas other than the land areas of the thin metal plate.
    • 制造薄膜厚度不均匀的精细图案化的厚膜导体结构的方法包括以下步骤:在金属板之外的区域以外的区域上形成抗蚀剂,使用薄金属板作为阴极电镀薄金属板 电路密度不小于三线/毫米,厚度为15-200微米的导体,将电镀薄金属板接合到绝缘基板上,薄金属板面朝上并蚀刻薄金属板。 精细图案导体适用于小型线圈,高密度连接器和高密度布线。 进一步公开了一种制造没有侧面突起的精细图案化的厚膜印刷电路板的方法,包括以下步骤:在金属板上的除了陆地区域之外的区域上形成抗蚀剂,将薄金属板电镀至0.3-10μm的厚度 m,电流密度为0.05-2A / dm 2,以3-20A / dm 2的电流密度将薄金属板电镀到所需的最终厚度,并除去薄金属以外的所有或其他区域 盘子。
