Abstract:
1. A method for manufacturing light emitting diodes, comprising steps: providing a base having an upper electrically conductive layer and a lower electrically conductive layer formed on a top face and a bottom face thereof, respectively; forming a plurality of through holes extending from the upper conductive layer through the base to the lower conductive layer; forming a connection layer on an inner circumferential face of each of the through holes to connect the upper conductive layer with the lower conductive layer; filling a supporting material in each of the through holes, wherein the supporting material is made of electrically insulating material; forming a reinforcing layer on the upper conductive layer and the supporting material, wherein the reinforcing layer is made of electrically conductive material; electrically connecting a plurality of chips with the upper conductive layer; forming an encapsulant on the reinforcing layer to seal the chips; and cutting the base into a plurality of LEDs along the through holes; wherein each of the upper conductive layer and the lower conductive layer is divided by a plurality of grooves into discrete strips after forming the through holes; wherein the supporting material has a top face coplanar with that of the upper conductive layer; and wherein the reinforcing layer completely covers the top faces of the upper conductive layer and the supporting material.
