Method of preparing various single-side multilayer single-functional and single-side and double-side multilayer multifunctional printed electronic product by virtue of light induction

Abstract

The invention relates to a method of preparing various single-side multilayer single-functional and a single-side and double-side multilayer multifunctional printed electronic product by virtue of light induction, and relates to the technical field of printed electronics, and solves the problem that an existing inkjet printing electronic technology cannot realize the high-efficiency mass production of high-resolution electronic circuits. The method comprises the following steps: first selecting a substrate, then completing the design of circuit information or insulation layer information on a computer, controlling the radiation of optical beams by virtue of an optical beam controller, enabling the circuit information or insulation layer information to be stored in a photosensitive material, forming an electrostatic latent image of the circuit or insulation layer information, covering the photosensitive material with functional ink powder, converting the circuit information or insulation layer information into a visible ink powder circuit or insulation layer image, transfer printing the functional ink powder onto the substrate by virtue of hot-pressing sintering or electrostatic adsorption or the combination of the hot-pressing sintering and electrostatic adsorption, and roasting the substrate to form a circuit layer or an insulation layer. The method is also suitable for printing an integrated circuit.

Description

technical field

[0001] The invention relates to the technical field of printed electronics; in particular, it relates to a printed electronic technology using light-induced conductive toner to form circuits. Background technique

[0002] In the electronic information manufacturing industry, the traditional copper foil etching technology is widely used because of its mature technology, but it also brings environmental pollution due to its complicated manufacturing process, numerous production processes, large material consumption, and large amount of waste liquid. It was widely criticized because of the great pressure. In order to overcome the cumbersome process and serious pollution of traditional copper foil etching technology, and meet the development requirements of a new generation of flexible circuits and wearable circuits, inkjet printed electronics technology emerged as the times require.
