Welding jig

Abstract

The invention relates to a semiconductor illumination technology, in particular to a welding jig for manufacturing an LED light source. The welding jig comprises a plate-shaped jig body, wherein the jig body is provided with a first plane and a second plane, the first plane is also provided with a concave aluminum base plate containing position, the bottom surface of the aluminum base plate containing position is provided with a solder passing hole penetrated with the second plane, and also provided with an LED bulb containing cavity, and the side surface of the LED bulb containing cavity is provided with an opening communicated with the solder passing hole; and the welding jig is also provided with an aluminum base plate clamping device. A welding method comprises the steps of: S1, providing the LED bulb, providing an aluminum base plate, and providing a welding jig; S2, installing the LED bulb and the aluminum base plate on the welding jig, and clamping; S3, carrying out wave soldering; and S4, removing the welding jig. The invention provides a welding jig capable of automatically welding the LED bulb with a lens at a high speed.

Description

technical field [0001] The invention relates to semiconductor lighting technology, in particular to a welding jig for manufacturing LED light sources. Background technique [0002] For LED lighting, it is very important to solve the problem of heat dissipation. In order to quickly transfer the heat generated by chips or LED bulbs to the outside, aluminum substrates are usually used instead of traditional PCB boards. [0003] In the prior art, the welding of LED bulbs to the aluminum substrate is done manually, which has low productivity and unstable quality. [0004] Some people also try to inform wave soldering to realize automatic production to improve efficiency and quality. However, when the wave soldering machine is soldering, the internal liquid tin temperature generally needs to be 220°C-250°C, and the lens on the LED bulb is made of plastic material. Here Deformation or melting will occur at high temperature, and high temperature will cause the LED chip to age and ...

[0003] In the prior art, the welding of LED bulbs to the aluminum substrate is done manually, with low productivity and unstable quality

[0004] Some people also try to inform wave soldering to realize automatic production to improve efficiency and quality. However, when the wave soldering machine is soldering, the internal liquid tin temperature generally needs to be 220°C-250°C, and the lens on the LED bulb is made of plastic material. Here Deformation or melting will occur at high temperature, and high temperature will cause aging of LED chips and reduce lifespan

Therefore, wave soldering cannot be applied to the welding of LED bulbs with lenses at present.
