<P>PROBLEM TO BE SOLVED: To provide rolled copper alloy foil for double-sided copper-clad laminate inhibiting a break when manufacturing the double-sided copper-clad laminate, and to provide a method of manufacturing the double-sided copper-clad laminate using the same. <P>SOLUTION: The rolled copper alloy foil 4 for double-sided copper-clad laminate containing 50-300 mass ppm of Ag as an additive element with the balance being tough pitch copper specified by JIS-H3100-C1100 or oxygen-free copper specified by JIS-H3100-C1020 exhibits: 90-120 GPa Young's modulus in a rolling direction when annealed at 150°C for 30 minutes; and 60-75 GPa Young's modulus in the rolling direction when annealed at 350°C for 30 minutes. Onto the rolled copper alloy foil 4 applied with a varnish-like resin composition 2a on one face using an application roll 10, 11, or the like and cured in a drying apparatus 15, coil-shaped second copper foil 6 is continuously unrolled to be laminated between heated laminate rolls 20, 21 in a continuous manner. <P>COPYRIGHT: (C)2013,JPO&INPIT |
