Patent ID: 8008099

Claim:
A method for manufacturing an LED package structure with concave area for positioning heat-conducting substance, comprising: providing a substrate unit, wherein the substrate unit has a substrate body, at least one concave space formed on a top surface of the substrate body, a plurality of positive pads exposed on the top surface of the substrate body and a plurality of negative pads exposed on the top surface of the substrate body; placing a plurality of heat-conducting adhesive balls in the at least one concave space; placing a plurality of LED chips on the heat-conducting adhesive balls, wherein each LED chip has a positive electrode and a negative electrode; transforming the heat-conducting adhesive balls into a heat-conducting adhesive layer by a reflow process in order to fix the LED chips in the at least one concave space of the substrate unit; electrically connecting each LED chip between each positive pad and each negative pad by a plurality of wires, wherein every two wires are respectively electrically connected between the positive electrode of each LED chip and each positive pad and between the negative electrode of each LED chip and each negative pad; and forming a translucent package resin body on the top surface of the substrate body in order to cover the LED chips and the wires.
