Abstract

The invention discloses a metal pattern, and a preparation method and a preparation device of the metal pattern, and relates to the technical field of printed electronics. The preparation method comprises the following steps: providing a composite material belt, the composite material belt comprises low-melting-point metal and a material belt substrate for bearing the low-melting-point metal, providing a printing substrate, wherein the surface of the printing substrate is provided with a first region adhered with low-melting-point metal and a second region not adhered with the low-melting-point metal; pressing the composite material belt and the printing substrate, and providing a heat source at the pressing position of the composite material belt and the printing substrate, so that the low-melting-point metal at the pressing position on the composite material belt is melted and adhered to the first region of the printing substrate; and before the low-melting-point metal is solidifiedagain,separating the material belt and the printing substrate, and obtaining a metal pattern attached to the surface of the printing substrate. According to the preparation method, the low-melting-point metal is in a molten state only in a short time, so that the oxidative deterioration degree of the low-melting-point metal in air is greatly reduced, and the reliability and stability of the low-melting-point metal printed metal pattern are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of printed electronics, in particular to a method and device for preparing a metal pattern. Background technique [0002] In the traditional field of printed electronics, the preparation of electronic circuits often requires complicated processes, such as the preparation of etched circuit boards. This preparation process is not only complicated and inefficient, but also accompanied by the generation of toxic waste liquid and gas, which pollutes the environment. Not suitable for preparation of small batch production. Low-melting-point metals are metals or alloys with a low melting point, which can be in a liquid state under appropriate temperature conditions, so as to meet the requirements of paste printing, without the need to use traditional cumbersome exposure and etching processes to prepare printed electronics. Moreover, low-melting point metals also have good electrical conductivity, non-toxic and non-...
