Abstract

A freezing printing device comprises an ink pool, a heat conducting mold, a vertical moving mechanism and a temperature control mechanism, wherein the ink pool is used for accommodating liquid metal,and the top part of the ink pool is an open structure; the bottom part of the heat conducting mold is provided with a printed pattern, and the heat conducting mold is positioned above the opening of the ink pool; the vertical moving mechanism drives the heat conducting mold to move in a vertical direction, and is used for controlling the bottom part of the heat conducting mold to be in contact with, immersed in or separated from the liquid metal in the ink pool; and the temperature control mechanism performs heat conduction with the heat conducting mold, and is used for transferring low temperature to the heat conducting mold and controlling the liquid metal in contact with the printed pattern to be cooled and solidified. Compared with the traditional printing methods such as spray printing and pressurized printing in the liquid metal printing field, the novel liquid metal printing mechanism is provided, and the selectivity of liquid metal printing methods under different environmentsand conditions is expanded.

Description

technical field [0001] The invention belongs to the technical field of metal printing, and in particular relates to a liquid metal-based freezing printing device. Background technique [0002] Traditional planar circuit manufacturing technology often requires complex process flow. First, it is necessary to use a plotter or printer to form a black and white image on a special software layout, and then send the black and white image to a professional production factory for plate making. In the traditional printed circuit board production process, there are high requirements in terms of equipment quantity and plate making technology, which lead to long production time and high cost, and the circuit cannot be partially corrected during the production process. Due to the various shortcomings of traditional circuit processing methods, researchers have developed a variety of fast planar circuit printing methods, as well as metal 3D printing technologies. However, the current plana...
