Description

Technical Field

[0001] This invention relates to the field of circuit board processing, and more particularly to an antioxidant treatment method for circuit boards. Background Technology

[0002] In the electronics industry, circuit boards are frequently subjected to adverse environments such as humidity and high temperatures during manufacturing, storage, and transportation. This can lead to oxidation and corrosion on their surface and internal components, affecting the overall stability and lifespan of the circuit board. For example, the following problems may arise: 1. Humidity: Excessive humidity can cause the circuit board to become damp, affecting the normal operation of circuit components. 2. Static electricity: Static electricity and oxidation, even internally, can damage electronic components on the circuit board, causing short circuits or poor contact. 3. Temperature: Both excessively high and low temperatures can affect the performance and stability of the circuit board. 4. Dust and contamination: Dust and contamination on the surface of the circuit board can affect signal transmission and heat dissipation. 5. Mechanical damage: During storage, the circuit board may be damaged by compression or impact, further affecting the overall stability and lifespan of the circuit board.

[0003] Therefore, there is an urgent need to provide an improved method for anti-oxidation treatment of circuit boards to overcome the above defects. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-oxidation treatment method for circuit boards. This method is simple and effective, forming an anti-oxidation coating on the surface of the circuit board to protect it from the effects of humidity, oxygen, temperature, etc., preventing oxidation and corrosion on its surface and inside, thereby ensuring the stable operation and service life of the circuit board.

This method is simple and effective. The antioxidant coating can protect the circuit board substrate from the effects of humidity, oxygen, and temperature, preventing oxidation and corrosion on its surface and internal structure, thus ensuring the stable operation and lifespan of the circuit board.

[0011] As an example, the antioxidant solution also includes soy protein and / or gelatin.

[0012] As an example, the preparation of the antioxidant solution includes mixing and stirring methanol, isopropanol, diethylene glycol and phenol, then adding soy protein and / or gelatin and stirring to obtain an antioxidant mixture, and then filtering the antioxidant mixture to obtain an antioxidant solution.

[0013] As an example, the drying temperature of the antioxidant solution is 70-85°C.

[0014] As an example, the drying time of the antioxidant solution is 4-5 hours.

[0015] As one embodiment, the conductive paint is conductive silver paste and / or conductive copper paste.

[0022] The antioxidant treatment method for circuit boards of the present invention will be further described below with reference to embodiments, but this does not limit the present invention. The method of the present invention aims to provide an antioxidant treatment method for circuit boards. This method is simple and effective, forming an antioxidant coating on the surface of the circuit board, thereby protecting the circuit board from the effects of humidity, oxygen, temperature, etc., and preventing oxidation and corrosion on its surface and inside, thus ensuring the stable operation and service life of the circuit board. Simultaneously, conductive paint is used to fix the antioxidant coating on the surface of the circuit board, thereby improving its antioxidant performance and stability.

[0023] In one embodiment of the anti-oxidation treatment method for circuit boards of the present invention, the method includes the following steps:

[0024] An antioxidant solution is prepared, the antioxidant solution comprising polyurethane and an antioxidant;

[0025] Provide the circuit board and clean the circuit board;

[0026] An antioxidant solution is prepared, wherein the antioxidant solution comprises methanol, isopropanol, diethylene glycol, and phenol;

[0027] The antioxidant solution is sprayed onto the circuit board and dried to form an antioxidant coating; and

[0028] A conductive paint is sprayed onto the antioxidant coating and dried to form a conductive paint layer.

[0029] The method of this invention uses methanol, isopropanol, diethylene glycol, and phenol as raw materials to prepare a specific antioxidant solution, which is then sprayed onto the surface of a circuit board to form an antioxidant coating. Furthermore, a conductive paint is sprayed on top to further fix the antioxidant coating to the surface of the circuit board, thereby further improving its antioxidant performance and stability. This method is simple and effective. The antioxidant coating can protect the circuit board substrate from the effects of humidity, oxygen, and temperature, preventing oxidation and corrosion on its surface and internal structure, thus ensuring the stable operation and lifespan of the circuit board.

[0030] In one specific embodiment, the surface of the circuit board is first cleaned to remove oil and impurities.

[0031] Specifically, a mixture of methanol, isopropanol, diethylene glycol, and phenol is used as the main raw material for the antioxidant solution. Preferably, a small amount of functional materials, such as soy protein and / or gelatin, can be added. The preparation steps of the antioxidant solution are as follows: First, diethylene glycol and phenol are added to an appropriate amount, such as 1 L of methanol and isopropanol solution, respectively, in a weight ratio of 1.5:1-2:1, and stirred until homogeneous. Then, an appropriate amount of functional materials such as soy protein or gelatin is added and stirred. Finally, the resulting antioxidant mixture is filtered through a filter to obtain the antioxidant solution.

[0032] Next, an antioxidant solution is sprayed onto the surface of the circuit board and then dried. Specifically, the drying process is carried out at a temperature of 70-85°C for 4-5 hours, thereby forming an antioxidant coating on the surface of the circuit board. Optionally, the thickness of the antioxidant coating is 50-80 μm.

[0033] Finally, after the anti-oxidation coating is formed, conductive paint is sprayed onto the surface of the circuit board and dried. Specifically, the drying temperature is controlled at 50-75°C, and the time is controlled at 2-3 hours, thereby forming a conductive paint layer on the anti-oxidation coating. Preferably, the conductive paint is made of conductive silver paste and / or conductive copper paste. Preferably, the thickness of the conductive paint layer is 20-30 μm. Thus, the conductive paint fixes the anti-oxidation coating to the surface of the circuit board, giving it durable anti-oxidation properties.

[0034] In summary, the method of this invention uses methanol, isopropanol, diethylene glycol, and phenol as raw materials to prepare a specific antioxidant solution, which is then sprayed onto the surface of a circuit board to form an antioxidant coating. Furthermore, a conductive paint is sprayed on top to further fix the antioxidant coating to the surface of the circuit board, thereby further improving its antioxidant performance and stability. This method is simple and effective. The antioxidant coating can protect the circuit board substrate from the effects of humidity, oxygen, and temperature, preventing oxidation and corrosion on its surface and internal structure, thus ensuring the stable operation and lifespan of the circuit board.
