Abstract

The invention relates to a bright copper film or copper alloy film anti-reflection process. The process includes: performing black oxidation treatment on the bright copper film or copper alloy film. The temperature of the black oxidation treatment is 40-60 °C and the time is 0.5-0. 5min, drying after the treatment, which reduces the reflectivity of the copper film or copper alloy film; the thickness of the bright copper film or copper alloy film is 0.1-1 μm, and the reflectivity within the wavelength of 380-780nm is > 30%. The invention realizes the precise control of the thickness of the copper oxide layer through the preparation of the reagents and the optimization of the process conditions. Under the premise of ensuring that the conductivity of the copper film or copper alloy film meets the requirements, its reflectivity is greatly reduced. The average reflectance of the copper film or copper alloy film in the wavelength range of 380-780nm is reduced to below 15%, which has a good application prospect. .

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a bright copper film or copper alloy film anti-reflection process. Background technique [0002] Copper and copper alloys are metal materials with good conductivity and low cost, and are the most important conductive substances on circuit boards, display screens and other devices. One of the main purposes of black oxidation treatment of copper and its alloys in the prior art is to form a protective layer on the metal surface to prevent copper and its alloy parts from being exposed to H in the atmosphere. 2 S, SO 2 The second main purpose is to form a blackened layer with suitable roughness on the copper surface of the inner layer copper of the multilayer circuit board to strengthen the copper surface. The bonding force between the surface and the prepreg. [0003] In practical applications, the thickness of copper or copper alloy treated by the existing black oxidati...
