Problems solved by technology

Although these solutions are real-time sampling, they cannot be analyzed and observed in real time. It is necessary to analyze the printing results after printing and compare them with the printing parameters. This not only reduces the printing efficiency to a certain extent, but also makes it difficult to find errors during the printing Defects are corrected in a timely manner

Abstract

The invention belongs to the technical field of printed electronics, and relates to an optical path system for real-time monitoring of micro-nano structure morphology in inkjet printing. The beam emitted by the laser passes through an attenuator to adjust the energy of the beam. Convex lens, the light finally converges on the CCD camera, and the CCD camera is connected to an external computer. The printed structure on the printed sample can be observed in real time through the computer. According to the focal length of the selected convex lens, the result observed by the computer is a scaled image of the printed structure. ; The optical path is simple and intuitive, the components are convenient and adjustable, the principle is reliable, the operation is convenient, and it is easy to implement. It can be widely used in various micro-nano structures and electronic manufacturing fields based on inkjet printing technology.

Description

Technical field: [0001] The invention belongs to the technical field of printing electronics, and relates to a real-time monitoring system for inkjet printing, in particular to a real-time monitoring optical path system for micro-nano structure morphology in inkjet printing. Background technique: [0002] Inkjet printing technology (InkjetPrinting) is a kind of "direct write" printed electronic technology, which uses gas pressure, electric field force or other forms of force to spray the functional oil film drop by drop on the surface of various substrates under the precise control of the computer. , to obtain specific micro-nano structures or thin films. This technology has the advantages of low cost, environmental friendliness, high efficiency and direct writing, and has been widely used in the field of new electronic materials in recent years. According to the different ways of inkjet printing, inkjet printing can be divided into two types: continuous inkjet printing (the...
