摘要:
Disclosed are a printed circuit board for improving the tolerance of embedded capacitors and a method of manufacturing the same. The printed circuit board having embedded capacitors is manufactured by transferring and embedding a circuit layer having a lower electrode formed through an additive process into a resin insulating layer, and thereby is minimized in the circuit tolerance conventionally caused by an etching process to thus be applied to capacitors for RF matching.

摘要:
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.
