Abnormal curing problem and solution of high-temperature conductive silver adhesive

With the development of electronic products towards miniaturization and high performance, the requirements for conductive connection materials are also increasing.High temperature conductive silver adhesiveDue to its excellent conductivity, mechanical strength, and ability to adapt to various substrates, it is widely used in various precision electronic components. However, if poor curing occurs during use, it will have a serious impact on the quality of the final product. Therefore, understanding and solving the problem of solidification abnormalities is the key to ensuring product reliability.

Analysis of the causes of solidification abnormalities

1. Improper temperature control

The curing temperature is one of the primary factors determining whether the conductive silver paste can be fully cured. If the temperature is too low, the curing agent may not be activated; On the contrary, excessive temperature may cause colloid coking or decomposition. In addition, uneven temperature distribution can also cause insufficient solidification in some areas.

2. Influence of humidity

Moisture in the air entering a high-temperature conductive silver adhesive container that is not completely sealed can cause hydrolysis of the curing agent, thereby reducing its activity or even rendering it ineffective. This situation is particularly prone to occur during the recovery and handling stages after opening.

3. Colloidal deterioration

Over time or under poor storage conditions, such as exposure to high temperatures,High temperature conductive silver adhesivePhysical and chemical changes may occur, such as color changes, particle precipitation, etc., which can affect its normal curing process.

4. Material compatibility issues

Some surface characteristics of the substrate may not be conducive to the good adhesion of conductive silver paste, thereby affecting the curing effect. In addition, subtle differences between different batches may also lead to different curing behaviors.

5. Equipment aging or insufficient power

If the UVLED curing machine or other heating device used for curing has problems such as light source aging and insufficient power, it will be difficult to provide sufficient energy to promote the curing reaction of high-temperature conductive silver paste.

Solution

1. Accurately control the curing temperature

Ensure that the curing temperature is set according to the manufacturer's recommended parameters and use a precise temperature control system to avoid local overheating or underheating. regardingResearch Platinum YB6001 High Temperature Conductive Silver AdhesiveAs for the recommended curing temperature, it is around 180 ° C and the duration is about half an hour.

2. Strengthen humidity management

When storing and using high-temperature conductive silver paste, the environment should be kept dry and the number of times the lid is opened should be minimized to prevent moisture from entering. Vacuum packaging or adding desiccants can be considered to further protect the product from moisture damage.

3. Regularly check the colloidal state

Carefully observe the appearance characteristics such as color and fluidity of high-temperature conductive silver paste before each use, and conduct simple tests if necessary to confirm whether it is still in good condition. Once any abnormal signs are found, new colloids should be replaced promptly to ensure construction quality.

4. Improve material compatibility and consistency

Select substrates that have undergone strict screening and have good adhesion, while ensuring that the high-temperature conductive silver adhesive used comes from the same production batch, in order to reduce curing uncertainty caused by material differences. Produced by Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum YB6001 High Temperature Conductive Silver AdhesiveWe have adopted advanced production processes and technologies to ensure the stability and consistency of our products.

5. Maintain and update curing equipment

Regularly calibrate and maintain the equipment used for curing to ensure it can provide stable and sufficient energy output. When the curing speed is significantly slowed down or the effect is poor, timely consideration should be given to replacing the aging light source or upgrading to a higher power equipment.

conclusion

In summary, the above measures can effectively prevent and solve the problem of abnormal curing of high-temperature conductive silver paste, thereby improving product quality and reliability. Especially when selecting high-quality suppliers such as Advanced Institute (Shenzhen) Technology Co., Ltd. to provide YB6001 high-temperature conductive silver adhesive, attention should be paid to detail management and process optimization to ensure that every step reaches the best state. In the future, with the advancement of technology, it is expected that more innovative methods and techniques will be developed to further enhance the application effect of high-temperature conductive silver paste.
