Abstract:
A flexible substrate 13 having conductor patterns 132 and 133, and a non-flexible substrate 111 with rigidity are disposed adjacent to each other in the horizontal direction. The flexible substrate 13 and the non-flexibie substrate 111 are covered with insulating layers 111 and 113 so that at least a portion of the flexible substrate is exposed. Vias 116 and 141 are formed in the insulating layers 111 and 116 so as to reach the conductor patterns 132 and 133 of the flexible substrate 13, and wirings 117 and 142 are formed by plating to reach the conductor patterns 132 and 133 through the vias 116 and 141. The insulating layers 114, 115, 144, and 145 are laminated on the insulating layers 111 and 113, and circuits 123 and 150 are formed for connection of wiring.
Abstract:
A package substrate (231) incorporating a build-up substrate having at least one structure in which a conductor layer and interlayer resin insulating layer are alternately laminated such that a conductive connecting pin (110) for establishing the electrical connection with another substrate is secured to said build-up substrate. Said package substrate comprises a pad (16) for securing said conductive connecting pin (110), wherein said pad (16) is covered with an organic resin insulating layer (15) having an opening (18) and connected to an inner conductor layer through a via hole, and said conductive connecting pin (110) is secured to said pad exposed to the outside through the opening through a conductive adhesive agent (17) formed in the opening.
Abstract:
A printed wiring board includes a mounting portion 60 on which a dual core processor 80 including two processor cores 81A and 81B in a single chip can be mounted, power supply lines 12A and 12B, ground lines 11A and 11B, and a first layered capacitor 40A and a second layered capacitor 40B which are independently provided for each of the processor cores 81A and 81B, respectively. Accordingly, even when the electric potentials of the processor cores 81A and 81B instantaneously drop, an instantaneous drop of the electric potential can be suppressed by the action of the layered capacitors 40A and 40B corresponding to the processor cores 81A and 81B, respectively. In addition, even when the voltage of one of the processor cores varies, the variation in the voltage does not affect the other processor core, and thus malfunctioning does not occur.
Abstract:
A multilayer printed circuit board (5010) comprises a core board (5030) and, as constructed on both sides thereof, a buildup wiring layer obtainable by building up an interlayer resin insulating layer (5050, 5150) and a conductor layer (5058, 5158) alternately with said conductor layers (5058, 5158) being interconnected by via holes (5160). The via holes (5060, 5160) are formed immediately over plated-through holes (5036) in the manner of plugging the through holes (5016) in the core board (5030). In a process for manufacturing the multilayer printed circuit board (5010), the through holes (5016) are pierced by laser light to be not larger than 200 µm in diameter.
