The size of the warp and the appearance of the double-sided copper-clad laminate obtained in the above were evaluated. The size of the warpage was obtained by cutting the obtained double-sided copper-clad laminate into 250 × 250 mm, etching the entire surface of the copper foil, placing it on the surface plate, and lifting it up at the four corners. The distance between the platen and the laminate was measured for 10 sheets, and the maximum value of the 10 sheets was defined as the amount of warpage. The appearance was evaluated by observing the front and back sides of the obtained double-sided copper-clad laminate by visual observation of 20 sheets, and the number of wrinkled concave portions and flaws was counted.
