    • A method for manufacturing a printed wiring board for reducting the size and increasing the density the wiring board, simplifying the process, and improving connection reliability and yield of the mounted components, and a photosensitive resin composition to be used for the printed wiring board. The method for manufacturing the printed wiring board is characterized by sequentially carrying out (i) the step of forming a solder resist over a circuit wiring board; (ii) the step of overlaying the solder resist with a premolded photosensitive resin composition; (iii) the step of exposing and developing the photosensitive resin composition layer to form a resist pattern of the photosensitive resin composition; (iv) the step of electroless-plating the whole surfaces of them; and (v) the step of separating the layer of the photosensitive resin composition. A photosensitive resin composition to be used for the printed wiring board and a layer of this resin composition are also disclosed.
    • 制造印刷电路板的方法,用于减小布线板的尺寸和增加密度,简化工艺,提高安装部件的连接可靠性和产量,以及用于印刷线路板的感光性树脂组合物。 制造印刷电路板的方法的特征在于:(i)在电路布线板上形成阻焊剂的步骤; (ii)用预成型的感光性树脂组合物覆盖阻焊剂的步骤; (iii)曝光和显影感光性树脂组合物层以形成感光性树脂组合物的抗蚀剂图案的步骤; (iv)化学镀它们整个表面的步骤; 和(v)分离感光性树脂组合物层的工序。 还公开了用于印刷线路板的感光性树脂组合物和该树脂组合物的层。
