Preparation method of multilayer electronic product

The invention discloses a preparation method of a multilayer electronic product. The preparation method comprises the following steps: (1) carrying out surface energy treatment on a substrate; (2) forming a hydrophilic and hydrophobic pattern on the surface of the substrate within a preset time after the surface energy treatment; (3) carrying out ink-jet printing on the substrate with the hydrophilic and hydrophobic pattern to obtain a printed pattern; (4) performing surface energy treatment on the substrate printed with the printed pattern; (5) printing an insulating layer on the surface of the substrate subjected to surface energy treatment; (6) performing surface energy treatment on the insulating layer; (7) forming a hydrophilic and hydrophobic pattern on the insulating layer subjected to surface energy treatment again; and (8) carrying out ink-jet printing on the hydrophilic and hydrophobic pattern formed again, and obtaining a printed pattern. By the adoption of the method, large-scale mass production o
