Abstract

The invention discloses an LED support electroplating method and an LED support. The invention relates to the technical field of electroplating. The method comprises the following steps of: 1, performing electroplating pretreatment on an LED support, cleaning dust and impurities on the surface of an LED support material, performing smooth surface treatment, uniformly fixing the LED support material by using a hanger, flushing the surface of the LED support material by using clear water, and activating the surface of the LED support material by using a plating aid; 2, carrying out first-stage electroplating. According to the invention, after first-stage electroplating, second-stage electroplating, third-stage electroplating and fourth-stage electroplating are performed, the surface of eachcoating is uniformly sprayed by using a flame gun; the coatings are made to tend to be melted, homogenized and then naturally cooled to form a coating crystallization structure, molecules are compactand uniform, the coverage rate is good, good heat conductivity and heat conduction performance are guaranteed, the LED support is connected with a heat conduction rod, the LED support is integrally heated and annealed, all structural layers of the LED support are fused, the integration degree is high, and the overall physical performance of the support is improved.

Description

technical field [0001] The invention relates to the technical field of electroplating, and more specifically, the invention relates to an electroplating method for an LED bracket and an LED bracket. Background technique [0002] SMD LED is a new type of surface-mounted semiconductor light-emitting device, which has the advantages of small size, large scattering angle, good uniformity of light emission, and high reliability. The light-emitting colors include various colors including white light. Therefore, it is widely used in various electronic products. In order to improve the overall performance of the LED bracket, electroplating treatment is required in the processing process. Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is the process of using electrolysis to make metal or other materials. The process of attaching a layer of metal film to the surface of the part, ...
