Analysis of the application effect of printing gold paste on different materials

Printing gold paste has a wide range of applications in electronic component manufacturing, solar cells, and other fields due to its excellent conductivity and stability. However, different substrate characteristics can have an impact on the printing effect of gold paste. This article explores the comparison of experimental data and discussesResearch Platinum Brand YB8107 Printing Gold PasteThe application effects on different materials and the relevant research results of Advanced Institute (Shenzhen) Technology Co., Ltd. were introduced.

With the continuous development of the electronics industry, the requirements for conductive materials are becoming increasingly high. Printing gold paste, as an important conductive material, is widely used due to its excellent conductivity, corrosion resistance, and good welding performance. However, different substrates have different effects on the adhesion, conductivity, and printing uniformity of gold paste. Therefore, understanding the application effects of gold paste on different materials is of great significance for optimizing production processes.

Experimental Design and Methods

This experiment selected several common substrates, including but not limited to glass, ceramics, stainless steel, and polyimide (PI) films, and usedAdvanced Institute (Shenzhen) Technology Co., LtdThe YB8107 printing gold paste produced by Yanbo brand was tested for printing. The experiment observes and records the performance indicators such as adhesion, conductivity, and printing uniformity of gold paste on different substrates by controlling the same printing conditions (such as printing speed, pressure, etc.).

Experimental results and analysis

1. Adhesion test

Testing through cross cutting methodwine of the best qualityThe adhesion on different materials is as follows:

• Glass: The adhesion between the gold paste and the glass surface is strong. After 24 hours of curing treatment, there is almost no peeling phenomenon, and the adhesion level is 5B.
• Ceramics: The surface of ceramics is relatively smooth, and the adhesion of gold paste is also good, but slightly inferior to glass, with an adhesion level of 4B.
• Stainless steel: Although the surface of stainless steel is relatively rough, due to the influence of its surface oxide layer, the adhesion of the gold paste is relatively weak, with an adhesion level of 3B.
• Polyimide film (PI): The flexibility of PI film makes its bonding with gold paste more tightly during the curing process, but due to the thermal stability of the film, the adhesion level is 3B.

2. Conductivity testing

The conductivity of gold paste on different materials was measured using the standard four probe method, and the results are as follows:

• Glass: resistivity of 0.04 Ω· cm.
• Ceramics: resistivity of 0.05 Ω· cm.
• Stainless steel: resistivity of 0.06 Ω· cm.
• Polyimide film (PI): resistivity of 0.04 Ω· cm.

3. Printing uniformity test

The printing uniformity of gold paste on different materials was observed through an optical microscope, and the results are as follows:

• Glass: Good printing uniformity and clear edges.
• Ceramics: Good printing uniformity, but slight burrs on the edges.
• Stainless steel: Due to its high surface roughness, the printing uniformity is generally average.
• Polyimide film (PI): Excellent printing uniformity and neat edges.

Data comparison and conclusion

By comparing the experimental data mentioned above, it can be seen that,Research Platinum Brand YB8107 Printing Gold PasteThe application effect is best on glass and PI film, with strong adhesion, excellent conductivity and printing uniformity. In contrast, the adhesion and conductivity on the surfaces of ceramics and stainless steel are slightly inferior.
