Abstract
A method of manufacturing a printed circuit board includes providing a substrate having at least one resin plate and a semi-cured sheet. A through hole is formed in the substrate to accommodate a radiator having an electrically conductive layer and an electrically insulated layer. The substrate and radiator are heat pressed to fully cure the epoxy and couple the substrate and radiator together. The excess resin is removed and electrically conductive layers are plated on the board. Surface circuits and a heat dissipating pattern are then etched into the conductive layer. An LED is attached to the printed circuit board. In some embodiments, a flexible segment is formed by removing a portion of the substrate. The radiator can have an electrically insulated layer extending at least partially across a surface of an electrically insulated and thermally conductive core.
