What to do if reflow soldering does not dissolve tin well?

Reflow soldering is a commonly used welding process for electronic components, which has the advantages of high efficiency and quality, and is widely used in the electronic manufacturing industry. However, sometimes we may encounter situations where reflow soldering does not dissolve tin well, which brings troubles to our work. So, what should we do when reflow soldering does not dissolve tin well?

We need to understand the reasons for poor solder dissolution in reflow soldering. There are many possible reasons, such as incorrect welding temperature, long or short welding time, and the presence of pollutants in the welding area. When facing these problems, we need to take targeted measures.

Firstly, we can check if the welding temperature is correct. The welding temperature of reflow soldering is very important, as high or low temperatures can lead to poor tin dissolution. We can solve this problem by adjusting the welding temperature to ensure that the temperature reaches the appropriate range.

Secondly, we can check if the welding time is appropriate. Long soldering time can lead to excessive heating of components, thereby affecting the quality of tin melting; If the welding time is too short, it may lead to unstable welding points. Therefore, we need to adjust the welding time according to the specific situation to ensure the welding quality.

In addition, we also need to pay attention to the cleanliness of the welding area. The presence of pollutants in the welding area can affect the welding quality, leading to poor tin dissolution. Therefore, before welding, we should ensure the cleanliness of the welding area and take corresponding protective measures to avoid the invasion of pollutants.

In addition, we can also choose higher quality welding materials and equipment to improve welding quality. Choosing suitable solder wires and welding equipment can provide better welding results and reduce the probability of poor soldering.

Finally, we can also improve welding technology by strengthening training and technical exchange. Continuously learning new knowledge and mastering advanced welding techniques can help us better solve the problem of poor tin dissolution in reflow soldering.

In short, when reflow soldering does not dissolve tin well, we need to comprehensively consider multiple factors and take corresponding measures. By adjusting the welding temperature and time, ensuring the cleanliness of the welding area, selecting high-quality welding materials and equipment, and strengthening training and technical exchanges, we can effectively solve the problem of poor tin dissolution in reflow soldering and improve welding quality. Let's work together to create a more efficient and high-quality electronic manufacturing industry!
