Abstract:
A method for manufacturing a printed circuit board with a heat dissipation element, said method comprising:attaching two alloy panels to each other using an insulation carrier layer interposed therebetween, each of said alloy panels serving to dissipate hear; attaching an insulation layer and a conductive layer on one surface of said each alloy panel; forming via holes by perforating the insulation layers and the conductive layers; forming a plating layer coupling each conductive layer to the alloy panel through the via holes; forming a circuit pattern layer on said each conductive layer; separating the two alloy panels with the circuit pattern layer from each other by dividing the insulation carrier layer; and attaching a heat sink panel to the other surface of at least one alloy panel.
