As shown, after the carrier 10 is removed, the solder layer 30 is partially covered in the encapsulant 80 and partially protrudes from the encapsulant 80, wherein a portion of the solder layer 30 protruding from the encapsulant 80 is convenient for subsequent electrons. The device is electrically connected. Since the solder layer 30 has a larger adhesion area than before to increase its adhesion, the board level reliability of the wafer can be improved. Following the above description, since the solder layer 30 has been previously provided on the carrier 10 by electroplating or electroless plating, after the carrier 10 is removed, the plating process is not required, and the process can be reduced. Moreover, in an embodiment, after the heat conductive layer 40 is formed, an ultra-roughening treatment may be performed to increase the bonding force between the heat conductive layer 40 and the encapsulant 80, thereby preventing delamination. In another embodiment, the steps before the manufacturing of the package carrier is completed may be the same as that of the second embodiment, and then the wafer packaging process and the removal of the carrier are the same as the above description, and no longer Repeat the description. According to the above, one of the features of the present invention is that the patterned film or the patterned template can be used as a mask for etching or material coating, which is quite flexible in the process, and the patterned template can be reused for the carrier process of the same pattern design. In order to reduce the manufacturing cost; one of the features of the present invention is that the electroplating process is not required after the wafer is packaged, the process steps and the fabrication time thereof can be reduced, and the error probability of the fabrication can be reduced due to the simplification of the steps. 1307143 r~V7: i2.ll-^ i thousand months s repair (.3⁄4 positive replacement narrow j) In summary, the present invention provides a method for manufacturing a package carrier and a method for manufacturing the same, in a carrier board The thermal conductive layer is provided to improve the problem of poor heat dissipation of the package. Moreover, the solder layer is formed before the wafer is packaged, so that the conductive circuit is not reserved for the plating process after the package is completed, so that the process can be reduced. In addition, the flexibility of the circuit layout can be increased. In addition, a solder layer is formed in advance before the package is packaged, which avoids the problem of the conductive line eversion when the carrier board is removed, and there is no doubt that the conductive line residue affects the electrical property. 'Ultra-roughening treatment on the heat-conducting layer can increase the bonding force between the heat-conducting layer and the encapsulating resin to improve the reliability of the package structure.
