Abstract

The invention discloses a 5G ceramic filter film material and a preparation method thereof, and belongs to the technical field of ceramic material preparation. The film layer material is of a four-layer composite structure, a matrix is ceramic, a middle transition layer sequentially comprises an alloy layer and a connecting layer, a surface layer is a silver layer, wherein the alloy layer is obtained by taking alloy metal as a cathode and carrying out magnetron sputtering deposition on the ceramic matrix by utilizing a multi-arc target, the connecting layer is obtained by taking Mo, Cu or Cr as a cathode and depositing on the alloy layer by utilizing the cylindrical multi-arc target, and the surface silver layer is obtained by taking silver as a cathode and carrying out silver metal deposition on the connecting layer by utilizing the multi-arc target and a cylindrical target. According to the 5G ceramic filter film material and the preparation method thereof, magnetron sputtering and multi-arc ion plating are combined to prepare the film layer material, so that the problems of low bonding strength of metal and ceramic, high treatment cost and pollution to chemical plating/electroplating environment are solved, the preparation technology is simple and convenient, and the prepared 5G ceramic filter film layer material has the advantages of compact structure, no obvious defects and low insertion loss.

Description

technical field [0001] The invention belongs to the technical field of ceramic material preparation, discloses a 5G ceramic filter film layer material, and relates to a preparation method of the film layer material, that is, a method for metal deposition on the surface of a 5G ceramic filter. Background technique [0002] The 5G ceramic filter is made of metal oxide materials such as calcium magnesium titanium. This ceramic material is made into a sheet and coated with silver on both sides as electrodes. After DC high-voltage polarization, it has a piezoelectric effect. Because the filter has the characteristics of stability and good anti-interference performance, it is widely used as frequency selection components in various electronic products such as 5G base stations, TVs, video recorders, and radios. And because of its advantages of stable performance, no adjustment, and low price, it replaces the traditional LC filter network. [0003] At present, the main method of de...
