Problems solved by technology

However, the single nozzle of electrofluid printing is too large to achieve the integration level like piezoelectric inkjet printing (inkjet), so the production efficiency is very low, basically in the laboratory state, and cannot be applied industrially

preparation example Construction

[0065] Such as figure 1 As shown, the present invention provides a kind of preparation method of multilayer electronic product, comprising:

[0066] S101, performing surface energy treatment on the substrate to make the surface of the substrate hydrophilic;

[0067] The substrate of the present invention needs to be subjected to surface energy treatment in advance, and the surface energy treatment is preferably strong oxidation treatment. The specific process includes: cleaning the substrate; drying the cleaned substrate; drying the dried substrate The substrate is subjected to strong oxidation treatment, and the strong oxidation treatment is at least one of ozone treatment, oxygen plasma treatment, and ultraviolet light treatment, so that active Si-O-(H) groups are formed on the surface of the substrate.

[0068] Specifically, when the strong oxidation treatment is ozone treatment, it has the advantages of simplicity, convenience, and strong versatility of equipment.

[006...

Embodiment 1

[0158] (1) select glass as the substrate, carry out strong oxidation treatment for 5-50 minutes (the preferred time is 30 minutes) to the highly active ozone component produced by the ultraviolet cleaning machine to the substrate, so that the substrate surface forms active Si- O-(H) group;

[0159] (2) Select a seal made of silicone rubber containing -O-Si-R groups, and the seal is made of polydimethylsiloxane;

[0160] (3) Within 1s after the end of the strong oxidation treatment, quickly roll the printing roller with the stamp fixed on the surface of the substrate with Si-O-(H) groups, and limit the contact pressure to about 1000Pa . The rolling speed is 50 mm / s, and the average contact time between the stamp and the surface of the substrate is approximately 1 ms based on the calculation that the width of the contact area between the printing roller and the plane is 50 microns. Changing the water contact angle of the substrate from about 15°C to about 70°C;

[0161] The s...

Embodiment 2

[0170] (1) Select glass as the substrate, and use a spray gun treated with atmospheric pressure plasma to process the substrate, with an average processing time of 3-5s, so that active Si-O-(H) groups are formed on the surface of the substrate;

[0171] (2) Select a seal made of silicone rubber containing -O-Si-R groups, and the seal is made of methyl vinyl silicone rubber;

[0172] (3) within 30s after the strong oxidation treatment, the printing roller fixed with the stamp is quickly rolled over the substrate surface with Si-O-(H) groups, and the contact pressure is limited to about 2000Pa, The rolling speed is 5 mm / s, and the average contact time between the stamp and the substrate surface is approximately 10 ms based on the 50 micron width of the contact area between the printing roller and the plane. This treatment makes the water contact angle of the substrate change from about 20°C to about 75°C;

[0173] The stamp is separated from the substrate with Si-O-(H) groups t...

Abstract

The invention discloses a method for preparing a multilayer electronic product, comprising: (1) performing surface energy treatment on a substrate; (2) forming a hydrophilic and hydrophobic graphics; (3) inkjet printing on substrates with hydrophilic and hydrophobic graphics to obtain printed patterns; (4) surface energy treatment on substrates printed with printed patterns; (5) surface energy treated substrates (6) surface energy treatment is carried out to the insulating layer; (7) forming hydrophilic and hydrophobic patterns again on the insulating layer after surface energy treatment; (8) spraying on the re-formed hydrophilic and hydrophobic patterns Ink printing to obtain a printed pattern. By adopting the invention, the printing of multi-layer fine circuits can be mass-produced on a large scale, the cost is low, it is beneficial to industrial application, it is environmentally friendly and energy-saving, and the subsequent process of waste liquid treatment is reduced.

Description

technical field [0001] The invention relates to the technical field of circuit printing, in particular to a preparation method of multilayer electronic products. Background technique [0002] The integrated and low-cost manufacturing of circuits is the main trend of industrial development. The printing processing method has its unique advantages in the manufacture of some electronic products with its simplified process and low cost. It is expected to be used in some circuits with low integration. widely used in manufacturing. For example, screen printing electrodes have become the standard process for photovoltaic cell production all over the world, and inkjet printing has become the mainstream technology for flexible OLED thin film packaging. [0003] In the past few decades, integrated circuits (including circuit boards and chips, etc.) have mainly subtractive standard processes, including a series of complex processing steps such as photolithography, development, and etc...
