Is conductive silver adhesive suitable for all types of LED chips

With the continuous advancement of LED technology, conductive silver paste plays an increasingly important role in LED packaging due to its excellent conductivity and thermal conductivity. However, are all conductive silver adhesives suitable for various types of LED chips? This article will explore this issue and present the findings of Advanced Institute (Shenzhen) Technology Co., Ltd“Research Platinum YB6018 LED Conductive Silver Adhesive”For example, by comparing experimental data, analyze its performance on different LED chips.

The basic principle of conductive silver paste

Conductive silver adhesive is an adhesive with certain conductivity properties after curing or drying, usually composed of a matrix resin andconductive fillerThe main component is conductive particles. By the adhesive effect of the matrix resin, conductive particles are bonded together to form a conductive path, achieving conductive connection of the bonded material. This adhesive not only needs to have good conductivity, but also needs to have sufficient mechanical strength and thermal stability.

Differences in demand for different types of LED chips

Different LED chips, due to their different materials and purposesConductive silver adhesiveThe requirements also vary. For example, blue LED on sapphire substrate, red LED on silicon substrate, and ultraviolet LED on silicon carbide substrate have differences in operating temperature, environmental conditions, and required conductive silver paste characteristics.

Characteristics of YB6018 LED Conductive Silver Adhesive from Yanbo Brand

According to data from Advanced Institute (Shenzhen) Technology Co., Ltd,Research Platinum YB6018 LED Conductive Silver AdhesiveIt has excellent conductivity, shear force, and rheological properties, and low moisture absorption. Its thermal conductivity reaches 25.8 W/m · K and its shear strength is 14.7 MPa, making it suitable for packaging high-power and high brightness LEDs. These performance parameters indicate that YB6018 is a high-performance conductive silver adhesive product.

Experimental design and data comparison

To verify the research platinum brand YB6018LED conductive silver adhesiveThe applicability on different LED chips was tested by Advanced Institute (Shenzhen) Technology Co., Ltd. as follows:

1. Blue LED on sapphire substrate: YB6018 exhibits good adhesive strength and conductivity under 150 ° C curing conditions. After 1000 hours of aging testing, the resistance change rate of conductive silver paste is less than 5%, proving its stability in blue LED.

2. Silicon based red LED: Due to the special properties of silicon substrate, conductive silver paste needs to have better thermal and chemical stability. The experimental results show that YB6018 maintains good conductivity and resistance increases by no more than 3% after 500 hours under 85 ° C/85% humidity conditions.

3. Silicon carbide based UV LEDs: For high-power UV LEDs, conductive silver paste needs to withstand higher operating temperatures. After continuous illumination for 1000 hours, the resistance change rate of YB6018 is less than 4%, demonstrating excellent temperature resistance performance.

Compared with other brands of conductive silver adhesives in the market, the YB6018 brand of Yanbo performs well in various performance tests. For example, in the aging test of blue LED, a competitor's resistance change rate reached 10% under the same conditions, while YB6018 was only 5%; In the humidity test of red LED, the resistance of a competitor increased by 7%, while YB6018 only increased by 3%.

conclusion

Through application testing of LED chips made of different materials,Advanced Institute (Shenzhen) Technology Co., LtdThe YB6018 LED conductive silver adhesive of the research platinum brand has shown wide applicability. However, the selection of conductive silver paste still needs to be determined based on specific application scenarios and the characteristics of LED chips. For some special types of LEDs, such as high-performance or applications in special environments, further adjustments to the formula of conductive silver paste or finding more suitable solutions may be necessary.

Overall, although conductive silver paste can meet the needs of LED chips in most cases, it still needs to be selected reasonably according to actual working conditions in certain specific situations. Future research will further explore improvement methods for conductive silver paste to meet the diverse packaging needs of LED chips.

The above data is for reference only, and specific performance may vary due to production processes and product specifications.
