Problems solved by technology

[0003] The present invention aims to solve the matching problem of green ceramic material and electrode slurry from the root. The method is to consider a package of process solutions from many angles such as raw material formula and slurry system in advance, rather than being limited to splitting like the traditional LTCC process. Discuss the LTCC process of ceramic material, the LTCC process of electrode paste, or the sintering process of LTCC

Abstract

The invention provides a solving scheme for customized matching of silver-coated copper electrode slurry and an LTCC membrane band, namely a similar all-side parameters-based customized matching scheme for membrane band casting slurry and silver-coated copper electrode slurry in an LTCC technology. A solving scheme for fundamentally and comprehensively solving the problem of poor tolerance of the LTCC technology is provided mainly for the problem of matching of porcelain and the electrode slurry. The adopted electrode slurry is prepared from silver-coated copper powder, so that the economic applicability of the solving scheme is also improved. The solving scheme provided by the invention has the characteristics of ordinary and easy-to-purchase materials, good process tolerance and the like, meets the green and energy-saving environmental protection requirements, has a good industrial application prospect, provides a solid foundation for high-speed development of LTCC industrialization of our country, and is expected to be applied on a large scale in multiple fields of wireless communication, aerospace and military, microwave-radio frequency device application, automotive electronic devices and the like.

Description

technical field [0001] The invention relates to a solution for customizing silver-clad copper electrode slurry to match an LTCC film belt, belonging to the field of low-temperature co-fired ceramics [LTCC]. Background technique [0002] There is an unavoidable and thorny technical problem in the LTCC process, that is, the matching of green ceramic materials and electrode pastes, because LTCC-related companies usually only develop and produce green ceramic materials (including porcelain powder, porcelain paste, film tape) alone. Or electrode paste, companies generally use trial and error to solve the matching problem of green ceramic material and electrode paste. However, the actual situation presents an infinite cycle of sample provision-trial and error-providing samples-retrial and error. Not to mention the long cycle, sometimes it is impossible to give a satisfactory matching solution even after tossing. Therefore, many domestic companies compare If you are conservative, ...
