This application claims the benefit of Korean Patent Application No. 10-2010-0097930, filed on Oct. 7, 2010, entitled “Printed Circuit Board Having Electronic Components Embedded Therein” which is hereby incorporated by reference in its entirety into this application.
Meanwhile, a surface-mounting process using the flip chip technology is configured in a manner such that external connecting terminals (i.e., bumps) having a size ranging from several tens to several hundreds of μm are formed on an electronic component using materials such as gold, solder and other metals, the electronic component including the bump formed thereon is flipped over so that the surface of the component faces a printed circuit board, and the electronic component is mounted on the printed circuit board on the other side, that is, flipped over, unlike the process using existing wire bonding technology.
FIGS. 1 to 5 are cross-sectional views schematically showing a printed circuit board having electronic components embedded therein according to a first embodiment of the present invention. The printed circuit board having electronic components embedded therein (hereinafter referred to as “a printed circuit board”) according to the present invention is described with reference to the drawings.
The internal insulating layer 300 is stacked on both sides of the metal core layer 100 in which the electronic component 200 is embedded. When the printed circuit board is configured to be multilayered, the insulating layer contacted with the metal core layer 100 is referred to as “an internal insulating layer” in this specification in order to discriminate it from other insulating layers.
The circuit patterns 400 may be defined including a first via v1 connected to the terminal of the electronic component 200 or the metal core layer 100, and the first via v1 is formed by forming a through hole using a YAG laser or a CO2 laser and then forming a plating layer on the internal wall of the through hole using the above-described process.
The build-up layer 600 is manufactured by repeating a process of stacking an insulating layer 610 on the circuit patterns 400 and then forming another circuit pattern 620 using a plating or printing method or the like. More particularly, the build-up layer 600 is implemented by stacking a separate insulating material, forming a via hole using a YAG laser or a CO2 laser and then forming the circuit patterns including a via by a Semi-Additive Process (SAP), a Modified Semi-Additive Process (MSAP), or the like.
In this case, as shown in FIG. 5, the electronic component 200′ may include a through silicon via (TSV) to connect the ground terminal 230′ to the other surface, wherein the ground terminal 230′ may be connected to the metal core layer 100 through the conductive adhesive 700.
Provided that in the electronic component 200′ employed in the present invention, the ground terminal 230′ among the plurality of terminals is only formed on the other surface thereof.
Furthermore, by connecting to the metal core layer 100 through the conductive adhesive 700, it is advantageous in that the ground terminal 230′ of the electronic component 200′ is directly connected to the metal core layer 100 without requiring the connection of the ground patterns 430 as shown in FIG. 5.
FIGS. 6 to 8 are cross-sectional views schematically showing a printed circuit board having electronic components embedded therein according to a second embodiment of the present invention. The printed circuit board having electronic components embedded therein (hereinafter referred to as “a printed circuit board”) according to the present invention is described with reference to the drawings. It should be noted that details of the same configurations as the printed circuit board having electronic components embedded therein according to the first embodiment as described with reference to FIGS. 1 to 5 above are omitted.
In the printed circuit board according to the present embodiment, a metal core layer 100 is connected to the ground terminal of an external power supply and is grounded, and a groove part 150′ is formed to accommodate the electronic component unlike the first embodiment.
Furthermore, the electronic component 200 is embedded in the groove part 150′ and the internal insulating layer 300 is stacked on one side or both sides of the metal core layer 100.
In the printed circuit board according to the present embodiment, since the electronic component 200 is mounted in the bottom surface of the groove part 150′ formed on the metal core layer 100, the electronic component 200 can be stably mounted and the area in which the electronic component is in contact with the metal core layer 100 increases, thereby improving heat radiation efficiency.
In the printed circuit board according to the present embodiment, in the case in which the electronic component 200 is embedded in the groove part 150′, resin adhesive or the like is coated on the bottom surface of the groove part 150′, and the lower surface of the electronic component 200 is accommodated so as to be mounted on the adhesive.
In this case, as shown in FIG. 7, when conductive adhesive 700 is coated, heat transfer ability is improved and therefore heat radiation efficiency is improved. Furthermore, as shown in FIG. 8, the electronic component 200′, the ground terminal 230′ among the plurality of terminals of which is formed on the other surface may be employed.
