摘要： There is provided a manufacturing method for an insulating resin circuit substrate, which is a manufacturing method for an insulating resin circuit substrate which includes an insulating resin layer composed of a polyimide resin and a circuit layer consisting of metal pieces disposed in a circuit pattern shape on one surface of the insulating resin layer. The manufacturing method includes a temporary fixing step of pressurizing the metal pieces toward the resin sheet material while heating the metal pieces to temporarily fix the metal pieces and a joining step of disposing a cushion material on a side of the metal pieces which are temporarily fixed and pressurizing the metal pieces and the resin sheet material in a laminating direction, while heating the metal pieces and the resin sheet material, to join the resin sheet material and the metal pieces. Regarding all the metal pieces, in a case where a ratio w/t of a minimum width w to a thickness t exceeds 0.5, a heating temperature in the temporary fixing step is 150°C or higher, and in a case where the metal pieces include a narrow-width metal piece having the ratio w/t of the minimum width w to the thickness t of 0.5 or less, the heating temperature in the temporary fixing step is 350°C or higher.

摘要： A method of making a multilayered circuitized substrate (101) in which a continuous process is used to form electrically conductive layers (65) which each will form part of a sub-composite (75, 75', 75"). The sub-composites (75, 75', 75") are then aligned such that openings (57) within the conductive layers (65) are also aligned, the sub-composites (75, 75', 75") are then bonded together, and a plurality of holes (113) are then laser drilled through the entire thickness of the bonded structure. The dielectric layers (67, 69) used in the sub-composites (75, 75', 75") do not include continuous or semi-continuous fibers therein, thus expediting hole formation there-through.
