Patent ID: 7523551

Claim:
A manufacturing method of a multi-layer circuit board embedded with a passive component, the method comprising the steps of: providing a conductive foil which has a first surface and a second surface, the conductive foil has at least a pair of metal protruding points with the same material as the conductive foil disposed on the first surface, the distance between the pair of metal protruding points substantially equal to the distance between the two electrical contacts of the passive component; providing the passive component, comprising two electrical contacts at two ends thereof; connecting the two electrical contacts of the passive component onto the corresponding metal protruding points of the conductive foil; providing a board having a core substrate with organic insulation layer thereon; stacking the conductive foil and the board, wherein the passive component is embedded in the organic insulation layer; and patterning on the conductive foil; wherein the metal protruding points are integral with the conductive foil as a whole.
