Manufacturing method of a multi-layer circuit board embedded with a passive component

摘要

A manufacturing method of a multi-layer circuit board embedded with a passive component includes the steps of: providing a conductive foil which has one or more pairs of metal protruding points; connecting a passive element to the corresponding metal protruding points; providing a board having a core substrate with organic insulation layer on a core substrate; stacking the conductive foil and the board, wherein the passive component is embedded in the organic insulation layer and patterning on the conductive foil.
