A kind of preparation method of electronic device or circuit diagram

Abstract

The invention discloses a manufacturing method of an electronic device or a circuit diagram. In the method, catalyst granules and fixing agent granules are mixed according to a certain ratio, mixtures of the catalyst granules and the fixing agent granules are applied to a flexible substrate by means of the electric charge imaging principle, and the required electronic device or the required circuit diagram is obtained in a metal chemical sedimentation method. In the method, as the solid catalyst granules are used, a pattern is applied to the substrate, and accuracy is high; in addition, efficiency is high and an application range is wide when the method is used for manufacturing the electronic device or the circuit diagram.

Description

technical field [0001] The invention relates to the field of manufacturing electronic components, in particular to a method for preparing electronic devices or circuit diagrams by using catalyst particles. Background technique [0002] According to the current situation in the field of electronic device manufacturing in my country, at present, there is no new technology that directly immobilizes solid catalyst particles on the substrate, and then obtains electronic devices or circuit diagrams, which is similar to the printing technology of electronic devices, through chemical deposition of metal ions. . We know that electronic printing technology has played an increasingly important role in the field of electronic device manufacturing. This technology can effectively reduce production costs and process complexity, and can prepare electronic structures with more superior performance and environmental sustainable development requirements. The existing electronic printing techn...

Problems solved by technology

[0003] 1. Since liquid ink usually contains organic solvents such as isopropanol, propyl acetate, and ethyl acetate, such organic solvents always exist in the process of printing electronic devices, and long-term contact with organic solvents is harmful to technology. The personnel's skin, central nervous system, respiratory system and other organs will cause certain damage

[0004] 2. Since the liquid ink adheres to the substrate has a certain degree of diffusion, the degree of diffusion will be affected by the characteristics of the ink itself and the condition of the substrate surface, which will cause a certain deviation between the printed pattern and the original design pattern

[0005] 3. In the existing electronic printing technology, the liquid ink must be attached to the substrate, which requires a high degree of adhesion of the ink. Therefore, it is usually required to carry out necessary chemical treatment on the surface of the substrate, which undoubtedly increases production. cost
