Abstract: Thermosetting resin composition and insulating adhesive film. The thermosetting resin composition comprises 30-70 parts of epoxy resin, 5-500 parts of a modified spherical silica powder, and 30-70 parts of a curing agent; the modified spherical silica powder comprises an amino-modified spherical silica powder with a D50 particle size of 0.1-2.0 ?m and a coefficient of variation of ?35% in particle size distribution.

Abstract: A laminate coated with asymmetric metal foils, and a printed circuit board including same. The laminate comprises one or at least two stacked low-modulus prepregs, and a metal foil, coated on one side of the one or at least two stacked low-modulus prepregs, or metal foils having different thicknesses coated on two sides of the one or at least two stacked low-modulus prepregs. The modulus of elasticity of the low-modulus prepreg is 22 GPa or less after the low-modulus prepreg is cured. A low-modulus prepreg having a modulus of elasticity of 22 GPa or less after curing is selected as an insulating material for a laminate coated with asymmetric metal foils, such that the resultant laminate and a printed circuit board manufactured therefrom have a relatively low A-state warpage and a warpage which is obtained after reflow soldering processing, thereby ensuring the reliability of the printed circuit board.
