LIGHT EMITTING DIODE PRINTED CIRCUIT BOARD CAPABLE OF IMPROVING PRICE COMPETITIVENESS

摘要

PURPOSE: A light emitting diode (LED) printed circuit board (PCB) is provided to maximize light reflection rates by combining an aluminum piece and a thermal conductive polymer.;CONSTITUTION: An aluminum piece (102) includes high reflection rates. A component is projected to the aluminum piece and thermal conductive polymer resin. A PCB is comprised of the components. An epoxy PCB (103) forms a circuit pattern layer. The PCB circuit board and the epoxy PCB are attached from each other.;COPYRIGHT KIPO 2013;[Reference numerals] (100) Graphite composite PCB of the present invention; (101) Thermal conductive polymer injection piece (Base substrate layer); (102) Aluminum piece (Reflection rate layer); (103) Epoxy PCB containing a circuit pattern layer
