    Abstract: An underfill composition having improved mechanical properties resulting from the inclusion of a novel "core-shell" substance. The core-shell substance includes a fine powder, whose particles each having an outer shell with a Tg significantly above room temperature, and an inner core with a Tg significantly below room temperature. The shell substance often includes an acrylate or methacrylate and the core includes a wide range of materials, such as acrylates and silicone or butadiene-based rubbers.

    Abstract: PROBLEM TO BE SOLVED: To obtain a printed circuit board having a decoupled ground bus and a power bus and an extremely large decoupling capacitor by laminating a first conductor foil coated, at least on one side thereof, with a dielectric material together with a second conductor foil on the coating of the dielectric material. SOLUTION: Copper sheets 10, 14 are punched according to a clearance hole pattern on the ground plane and a copper sheet 12 is punched according to a clearance hole pattern on the hot side ASM dry coating sheets 18, 20 are then pasted onto the upper and lower surfaces of the copper sheet 12 and an ASM dry coating sheets 22 is pasted onto the lower surface of the copper sheet 14. Subsequently, these copper sheet/ASM dry coating structures are laminated together with prefabricated cores 24, 26, glass cloths 36, 38 and outer copper foils 40, 42 to produce a composite multilayer board. The composite multilayer board is then punched and processed through plating and outer circuit are made, thus completing a board having four parallel capacitive planes 44, 46, 48, 50.

    Abstract: The electrical interconnections between an integrated circuit chip assembly are encapsulated and reinforced with a high viscosity encapsulant material in a single step molding process wherein a mold is placed over an integrated circuit chip assembly and encapsulant material is dispensed through an opening in the mold and forced around and under the integrated circuit chip by external pressure encapsulating the integrated circuit chip assembly. An integrated circuit chip assembly having a reinforced electrical connection which is more resistant to weakening as a result is stress created by differences in coefficient of thermal expansion between the integrated circuit chip and the substrate to which the integrated circuit chip is attached is produced.
