Problems solved by technology

Inkjet printing is limited by the accuracy of printer nozzles and printer ink, and the accuracy requirements of 0.5-5 μm are currently unattainable
The method of laser etching is to make the laser laser system laser engrave on the surface of ceramic material products. Due to the high temperature and high heat generated by the laser beam instantly, the ceramic surface will be vaporized, which will easily lead to problems such as pattern discoloration and ceramic substrates are easily damaged.
[0004] In summary, the metal surface layer on the surface of ceramic material products processed by the above existing methods is very rough, and the surface roughness, surface gloss and surface chromaticity are difficult to control, and there are problems such as low processing accuracy, easy deformation of graphics, and easy damage to ceramics. Substrate and other issues make it impossible to process micro-nano-level high-precision metal patterns

Abstract

The invention discloses a processing method of high-precision metal patterns on the surface of a ceramic material product. The processing method comprises the following steps of: carrying out pretreatment on the ceramic material product firstly, plating a metal film with the thickness of 0.01 micron to 100 microns on the surface of the ceramic material product, then coating a corrosion-resistant photosensitive material on the metal film, carrying out exposure and development on the metal film, etching the metal film by virtue of an etching solution finally, removing the cured photosensitive material after etching, exposing metal film layer patterns, and further carrying out electroplating or chemical plating treatment on the surface of a metal film layer according to the needs. The processing method is used for manufacturing high-precision micro-nano metal patterns on the surface of the ceramic material product. With the adoption of the processing method, as the manufactured metal patterns have the characteristics that colors and the electric conductivity are adjustable, the patterns can be arbitrarily designed, the grade and the ornamental value of the ceramic material product can be increased, a ceramic substrate is not damaged, and the cost is low.

Description

technical field [0001] The invention relates to a method for processing metal patterns on the surface of ceramic material products, in particular to a method for processing high-precision metal patterns on the surface of ceramic material products. Background technique [0002] With the development of science and technology, people have higher and higher requirements for making high-precision metal circuits or patterns on the surface of ceramic materials. At present, the traditional processing methods of metal patterns on the surface of ceramic materials mainly include screen printing, metal thermal spraying, inkjet printing, laser etching, etc., but all of them have the problem of low precision. [0003] Screen printing is first screen printing and then sintering at a certain temperature to obtain a surface metal pattern. Screen printing is limited by the diameter of the screen and the characteristics of the paste, and its printing accuracy is difficult to reach below 100μm...
