Problems solved by technology

[0006] However, the thermal conductivity of the insulating layer formed on the metal substrate is poor, so even if the metal substrate is used, the problem of low thermal conductivity cannot be avoided.
[0007] Therefore, if the heat dissipation of the LED chip cannot be realized normally, the LED chip as a semiconductor component will hav

Abstract

The present invention relates to a method for manufacturing an LED package. A method for manufacturing an LED package of the present invention comprises the steps of: preparing a metal member which is cut in a strip form; forming, on said metal member, a metal substrate in which an anode terminal and a cathode terminal are formed at predetermined intervals; mounting an LED chip on a chip-mounting portion of said metal substrate; wire-bonding said LED chip with the anode terminal and the cathode terminal; and integrally forming a molding unit and a lens unit at the upper part of said metal substrate.

Description

technical field [0001] The invention relates to a method for manufacturing an LED package, more particularly to a method for manufacturing an LED package that directly mounts an LED chip on a metal substrate to improve heat dissipation efficiency. Background technique [0002] Generally, a light emitting diode (LED: light emitting diode, hereinafter referred to as LED) is a diode that flows current in a semiconductor pn junction to emit light. Gallium arsenide (GaAs) is a light emitting diode used for infrared rays, gallium aluminum arsenide (GaAIAs) ) is used as an infrared or red light-emitting diode, gallium arsenide phosphide (GaAsP) is used as a red, orange or yellow light-emitting diode, gallium phosphide (GaP) is used as a red, green or yellow light-emitting diode, nitrogen Gallium nitride (GaN) is a white light-emitting diode that emits white light by mixing rare-earth materials chromium, thulium, and terbium with phosphors used as active ions. [0003] In addition,...
