Abstract:
PROBLEM TO BE SOLVED: To provide a coreless package substrate capable of having electric contact bumps with better uniformity in superfine pitch and altitude, and to provide a method of manufacturing the same. SOLUTION: The coreless package substrate includes a substrate body 2 constituted of an auxiliary dielectric layer 24 having a first surface 24a and a second surface 24b which are opposed to each other, an inner layer circuit 26 provided to the second surface, and a build-up structure provided to the second surface and inner layer circuit; and a plurality of electric contact bumps 25 each constituted of a metal column 252 having a first end 252a and a second end 252b which are opposed to each other and a solder layer 251 provided to the first end, wherein the second end of the metal column is positioned at the auxiliary dielectric layer and electrically connected to the inner layer circuit 26, and the first end of the metallic column and the solder layer protrude from the first surface of the auxiliary dielectric layer.

Abstract:
PROBLEM TO BE SOLVED: To provide a component having a contact capable of joining a holding body with a high holding force, and to provide a method of manufacturing the component. SOLUTION: A component 1 is provided with a mechanical contact 4 that joins the component 1 to a holding body 3, especially, to a printed circuit board. A coated part 6 made of an adhesive material is formed on the contact 4. The adhesive material contains an encapsulated adhesive. A method of manufacturing the component is provided for joining the component to the holding body, especially, to the printed wiring board, and a mechanical contact is provided on the component for joining the component to the holding body. The coated part 6, constituted by the adhesive material, is attached to the contact, and the adhesive material contains an encapsulated adhesive. COPYRIGHT: (C)2010,JPO&INPIT
