Patent ID: 7335522

Claim:
A method for assembling a light emitting device, comprising: providing a light emitting diode having a first electrode and a second electrode; providing a substrate sequentially from bottom to top having a conduction board, an insulation layer, and a conductive layer; forming a trench in said conduction board to divide said conduction board into a first portion and a second portion; filling said trench with an insulation material to form an insulation channel for insulating said first portion from said second portion; forming an opening in said conductive layer and said insulation layer to expose said conduction board; forming a connection layer in said opening, said connection layer coupling with said first portion of said conduction board and being insulated from at least one portion of said conductive layer; forming a hole penetrating through said substrate, said hole defining an inner surface; electroplating said inner surface with a conductive material for coupling said at least one portion of said conductive layer and said second portion of said conduction board; electrically coupling said first electrode of said light emitting diode with said connection layer; and electrically coupling said second electrode of said light emitting diode with said at least one portion of said conductive layer.
