PRINTED CIRCUIT BOARD WITH EMBEDDED CAPACITORS USING HYBRID MATERIALS, AND MANUFACTURING PROCESS THEREOF

摘要

A printed circuit board with embedded capacitors, and a method for manufacturing the PCB are provided to reduce a signal loss when transferring signals by using hybrid materials as a dielectric layer for the PCB(Printed Circuit Board). A first circuit layer and a fourth circuit layer are formed on respective surfaces of a double-sided copper laminate plate. Second and third circuit layers are formed on respective copper films of a hybrid copper laminate plate. Copper films are laminated on both sides of a hybrid dielectric layer containing liquid crystal polymer and ceramic powders. The second circuit layer includes a lower electrode and a first circuit pattern. The third circuit layer includes an upper electrode and a second circuit pattern. The lower and upper electrodes face each other. An insulation layer(107) is laminated between the double-sided copper laminate plate and the hybrid copper laminate plate. A single-sided copper laminate plate is laminated on the third and fourth circuit layers. A blind via-hole(113) and a through-hole(112) are formed on predetermined portions of the single-sided copper laminate plate. A plating layer is plated on the via-hole and the through-hole.
