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 μm and a coefficient of variation of ≥35% in particle size distribution. By using modified spherical silica powder in epoxy resin system and controlling its D50 particle size and coefficient of variation in particle size distribution, the resin composition can reduce melt viscosity of high-filling system and achieve a low melt viscosity in an insulating adhesive film conducive to the filling of fine circuits. The resin composition for preparation of a build-up adhesive FC-BGA film of a high-filling system has strong bite-etching resistance, low surface roughness after Desmear treatment, high adhesive force with electroless copper and low dielectric loss.

Abstract: A resin composition and the use thereof. The resin composition comprises the following components, in percentages by weight: 40-70% of a crosslinkable and curable resin and 30-60% of a filler. The filler is silicon dioxide prepared by means of an organosilicone hydrolysis method; the average particle size D50 of the silicon dioxide is 0.1-3 μm; and the particle size ratio D100:D10 of the silicon dioxide is less than or equal to 2.5. By means of the composition, a prepared adhesive film and resin-coated copper foil have a higher elongation rate, a higher peel strength, low CTE, low Df, better drilling processability and higher electrical strength. A finer line processing capability can be achieved, which can be applied to a printed circuit board material of a multilayer laminate, in particular a printed circuit board material of a multilayer laminate of thin lines.
