Abstract:
Disclosed is a PCB including an embedded passive component and a method of fabricating the same. The PCB includes at least two circuit layers in which circuit patterns are formed. At least one insulating layer is interposed between the circuit layers. A pair of terminals is vertically formed through the insulating layers, plated with a first conductive material, and separated from each other by a predetermined distance. The embedded passive component is interposed between the terminals and has electrodes formed on both sides thereof. The electrodes are separated from the terminals by a predetermined distance and electrically connected to the terminals through a second conductive material.

Abstract:
Disclosed herein is a carrier member for transmitting circuits, which is a component of a coreless printed circuit board having circuit patterns embedded therein, and which can be used to provide a high-density and highly reliable printed circuit board by forming protrusions only on the lower ends of the circuit patterns, a coreless printed circuit board using the carrier member, and methods of manufacturing the carrier member and the coreless printed circuit board.
Abstract:
Disclosed is a PCB including an embedded resistor and a method of fabricating the same. The PCB includes a plurality of circuit layers in which circuit patterns are formed. A plurality of insulating layers is each interposed between the circuit layers. The embedded resistor is made of a resistive material and received in a receiving hole formed in the plurality of circuit layers and the plurality of insulating layers such that walls defining the receiving hole extends from one of the circuit layers to another circuit layer. The receiving hole has a closed section, and a conductive material is plated on the opposite walls of the walls defining the receiving hole.
