  • Patent number: 9596754
    Abstract: A dry film includes a carrier film, a thermosetting resin composition layer, and a photocurable resin composition layer formed between the carrier film and the thermosetting resin composition layer. The thermosetting resin composition layer is formed by applying and drying a thermosetting resin composition. The photocurable resin composition layer is formed by applying and drying a photocurable resin composition. A method of producing a printed writing board includes forming a resin insulation layer which includes a thermosetting resin composition layer and a photocurable resin composition layer on the substrate, in the order of the thermosetting resin composition layer and the photocurable resin composition layer from a surface side of the substrate, patterning the resin insulation layer by photolithographic approach, and patterning the resin insulation layer by laser processing.

  • Publication number: 20150016072
    Abstract: The present invention provides a dry film capable of forming a cured coating film having an excellent laser processability and a desmear resistance, and a printed writing board using the same. Further, the present invention provides a method of producing a printed writing board for a flip-chip mounting substrate capable of simply and inexpensively forming a dam preventing from spreading an underfill, a printed writing board obtained by the method of producing, and a flip-chip mounting substrate in which a chip is subjected to flip chip mounting on the printed writing board. A dry film comprising: a carrier film and a photocurable resin composition layer (L1) formed by applying and drying a photocurable resin composition; and at least a thermosetting resin composition layer (L2) formed by applying and drying a thermosetting resin composition in a gap between the photocurable resin composition layer (L1) and the carrier film.
