<p>PROBLEM TO BE SOLVED: To provide the manufacturing method of a metal foil-clad laminated sheet, in which the rate of dimensional change and its scattering are small and the accuracy of a sheet thickness is favorable. SOLUTION: In a metal foil-clad laminated sheet, which is produced by piling-up a required number of prepregs, each of which is obtained by impregnating a glass woven fabric with a resin for a laminating sheet and then drying the fabric, under the condition that a metal foil is placed on one side or both the sides of the piled-up prepregs so as to pressurize the piled-up prepregs under heat in order to obtain a metal foil-clad laminating sheet, a prepreg, the resin flow of which is 0.5-3.0% when measured with a method written in IPC TM-6502, 3, 17, is employed. The preferable glass woven fabric to be used has the ratio between thread counts per 25 mm (warp thread count/woof thread count) of 1.0-1.2 and the thermal expansion coefficient of 3×10<-6> / deg.C or less. The preferable metal foil to be used has a hot elongation at 180 deg.C of 10-50 %.</p> |
