发明名称 CIRCUIT BOARD FOR DIRECT FLIP CHIP ATTACHMENT
摘要 A packaging method comprises: forming a circuit board by forming a substantially continuous conductive layer on an insulating board and removing selected portions of the continuous conductive layer to define an electrically conductive trace; laser cutting the electrically conductive trace to define sub-traces electrically isolated from each other by a laser-cut gap formed by the laser cutting; and bonding a light emitting diode (LED) chip to the circuit board across or adjacent to the laser-cut gap, the bonding including operatively electrically connecting an electrode of the LED chip to one of the sub-traces without using an interposed submount. A semiconductor package comprises an LED chip flip-chip bonded to sub-traces of an electrically conductive trace of a circuit board, the sub-traces being electrically isolated from each other by a narrow gap of less than or about 100 microns.
