How to prevent oxidation and contamination of surface welding gold paste during the welding process

In modern industrial manufacturing,Surface welding gold pasteAs a high-performance conductive material, it is widely used in fields such as electronics and electrical appliances, especially in high-precision and high-strength welding requirements, and its importance is self-evident. However, oxidation and contamination of the metal surface during the welding process have always been key factors affecting welding quality and product performance. This article will explore how to effectively prevent oxidation and pollution during the welding process, based on the technical background of Advanced Institute (Shenzhen) Technology Co., Ltd. and the characteristics of the surface welding gold paste of the Research Platinum brand.

1、 Overview of surface welding gold paste

Surface welding gold paste, such asResearch Platinum Brand Surface Gold Tin Welding Gold PasteDue to its excellent conductivity, high temperature stability, and good welding performance, it has become the preferred material in many industrial manufacturing fields. This type of gold paste usually contains a high proportion of gold powder, and through specific preparation processes such as screen printing, drying, and sintering, a dense and smooth solder film is formed to ensure the stability and reliability of circuit connections.

2、 Measures to prevent oxidation

1. Using protective gas: During the welding process, inert gases such as argon are used to protect the welding area, which can effectively isolate active gases such as oxygen and nitrogen in the air and reduce oxidation reactions on the metal surface. This is one of the most direct and effective methods to prevent oxidation.

2. Control welding speed: Properly control the welding speed to ensure that the metal surface has enough time to form a stable oxide film, while avoiding excessive oxidation caused by prolonged exposure time. This requires precise control in the welding process specification.

3. Choosing appropriate welding materials: Welding materials with good oxidation resistance, such as stainless steel, titanium, etc., can reduce the occurrence of oxidation reactions. At the same time, high-quality surface welding gold paste, such as the research platinum brand product, has been optimized in terms of composition and preparation process, and has a low tendency towards oxidation.

4. Deoxygenation measures: Adding some alloy elements with higher affinity for oxygen than the weld metal, such as aluminum, silicon, etc., to the welding material can consume oxygen in the weld through chemical reactions, thereby reducing the oxygen content.

3、 Measures to prevent pollution

1. Keep the operating environment clean: Welding operations should be carried out in a clean room or ultra clean workbench to ensure that dust, bacteria, and other pollutants in the environment do not enter the gold paste. This is the primary step in preventing pollution.

2. Use sterile tools and containers: All tools and containers that come into contact with the gold paste should undergo strict disinfection to avoid introducing external contamination. Disposable plastic utensils or metal utensils that have undergone high-temperature sterilization are ideal choices.

3. Control drying temperature and time: The drying process of gold paste needs to be carried out under appropriate temperature and time conditions to avoid contamination caused by gold paste denaturation or coagulation. Accurate control of drying parameters is crucial based on the characteristics of gold paste.

4. Avoid contamination by operators: Operators should wear clean work clothes, gloves, and masks to prevent human sweat, dandruff, hair, and other pollutants from coming into contact with the gold paste.

5. Adopting advanced preparation technology:Advanced Institute (Shenzhen) Technology Co., LtdIn the preparation process of low, medium and high temperature welding electrode gold paste, precise screen printing, strict drying and sintering condition control and other technical means are adopted to ensure the cleanliness and stability of the gold paste during preparation and application. These advanced processes are also applicable to the preparation and application of surface welding gold paste.
