    • An object of the present invention is to provide a process for producing a printed wiring board, which is advantageous not only in that the reduction in size and increase in density of the wiring board are achieved and further the steps are simplified, but also in that the connection reliability of mount parts and the yield are improved, and a photosensitive resin composition used in the process. The present invention is directed to a process for producing a printed wiring board, comprising the steps of: (i) forming a solder resist on a wiring board having a circuit; (ii) laminating a preliminarily molded layer of a photosensitive resin composition on the solder resist; (iii) subjecting the layer of the photosensitive resin composition to exposure and development to form a resist pattern of the photosensitive resin composition; (iv) subjecting the entire surface of the resultant board to electroless plating, and (v) stripping the layer of the photosensitive resin composition, wherein the steps are conducted in this order, as well as a photosensitive resin composition and the layer thereof used in the process.
    • 本发明的目的是提供一种制造印刷电路板的方法,其优点在于不仅能够实现电路板的尺寸减小和密度的增加,而且还简化了步骤,而且也在于 安装部件的连接可靠性和产量提高,并且在该方法中使用感光性树脂组合物。 本发明涉及印刷电路板的制造方法,其特征在于包括以下步骤:(i)在具有电路的布线板上形成阻焊剂; (ii)在阻焊剂上层叠感光性树脂组合物的预成型层; (iii)将感光性树脂组合物的层进行曝光和显影以形成感光性树脂组合物的抗蚀剂图案; (iv)使所得板的整个表面进行无电镀,和(v)剥离感光性树脂组合物层,其中依次进行所述步骤,以及光敏树脂组合物及其用于 的过程。
