Analysis of situations where platinum conductor paste is not suitable for use

1、 Overview

Platinum conductor paste plays an important role in many electronic and electrical applications, but it is not always an ideal choice. This article will focus onResearch Platinum Brand YB8206 Platinum Conductor PasteFor example, based on relevant research and experimental data from Advanced Institute (Shenzhen) Technology Co., Ltd., this paper explores under what circumstances platinum conductor paste is not suitable for use and proposes improvement suggestions.

2、 Limitations under high temperature oxidation environment

Experimental setup

Advanced Institute (Shenzhen) Technology Co., Ltd. conducted a comparative experiment by placing the YB8206 platinum conductor paste of Yanbo brand and another metal paste with good high-temperature oxidation resistance (labeled as paste A) in a high-temperature oxidation environment. The experimental temperature is set at 800 ° C and the duration is 100 hours, conducted in an oxygen rich environment (with an oxygen content of 21%).

Comparison of experimental data

• After 100 hours of high-temperature oxidation, it was observed under an electron microscope that a layer of oxide with a thickness of about 5-8 μ m had formed on the surface of the YB8206 platinum conductor paste from the research platinum brand. This oxide layer resulted in a decrease of approximately 30% in its conductivity. The initial conductivity was measured to be 1.2 × 10 ⁶ S/m using the four probe method, and after high-temperature oxidation, the conductivity decreased to 0.84 × 10 ⁶ S/m.
• Under the same conditions, the surface oxide layer thickness of slurry A is only 1-2 μ m, and the conductivity only decreases by about 10%. The initial conductivity is 1.0 × 10 ⁶ S/m, and after 100 hours, the conductivity is 0.9 × 10 ⁶ S/m.

Conclusion that is not suitable for use

In this high-temperature oxidation environment,Research Platinum Brand YB8206 Platinum Conductor PasteThe performance degradation is quite obvious, especially the significant decrease in conductivity. For some high-temperature electronic devices that require high conductivity stability, such as high-temperature sensor circuits in aerospace engines, this platinum conductor paste may not be suitable for use.

3、 Performance in high humidity and high salt spray environment

Experimental setup

Advanced Institute (Shenzhen) Technology Co., LtdDesigned an experimental chamber that simulates a high humidity and high salt spray environment. Place the YB8206 platinum conductor paste and a precious metal mixed paste with good corrosion resistance (marked as paste B) in it. The experimental environment is set to a relative humidity of 95%, a salt spray concentration of 5% (mass fraction), and a duration of 500 hours.

Comparison of experimental data

• After 500 hours of experimentation, composition analysis of the YB8206 platinum conductor slurry from Yanbo brand revealed significant adsorption of chlorine elements on its surface, indicating that chloride ions in the salt spray had an erosive effect on it. Its adhesion decreased by about 40%, and the initial adhesion measured by scratch method was 10N/cm ². After the experiment, the adhesion was only 6N/cm ².
• Under the same conditions, the adhesion of slurry B only decreased by about 15%, with an initial adhesion of 8N/cm ² and an experimental adhesion of 6.8N/cm ².

Conclusion that is not suitable for use

In high humidity and high salt spray environments, the adhesion of YB8206 platinum conductor paste from Yanbo brand decreases significantly. This may not be a suitable choice for electronic circuits that need to maintain structural stability in such harsh environments for a long time, such as ocean monitoring equipment circuits at the seaside.

Research on YB8206 platinum conductor paste with a specialized material for high-frequency circuitsSilver based conductor paste(marked as slurry C) for comparative experiments. Set the frequency of the alternating electric field to 10GHz and apply the electric field continuously for 10 hours.

Comparison of experimental data

• For the YB8206 platinum conductor paste of the research platinum brand, its dielectric loss significantly increases under an alternating electric field of 10GHz. By measuring with a network analyzer, the initial dielectric loss was 0.01, and after 10 hours of experimentation, the dielectric loss increased to 0.03.
• Under the same conditions, the dielectric loss of slurry C only increased from the initial 0.008 to 0.012.

Conclusion that is not suitable for use

In a high-frequency alternating electric field environment,Research Platinum Brand YB8206 Platinum Conductor PasteThe increase in dielectric loss is significant, which may not be suitable for applications such as high-frequency communication circuits that require strict dielectric performance, such as certain high-frequency circuit components in 5G communication base stations. This platinum conductor paste may not be suitable for use.

5、 Performance in other environments

In addition to the aforementioned environments,Platinum conductor pasteIt may also exhibit different characteristics in extreme low temperatures, strong radiation, and strong acid-base environments. For example, at extremely low temperatures, platinum conductor paste may become brittle and increase, affecting its mechanical properties; In a strong radiation environment, radiation damage may occur, affecting its conductivity; In strong acidic and alkaline environments, chemical corrosion may occur, leading to a decrease in its performance.

Conclusion that is not suitable for use

Therefore, when using the YB8206 platinum conductor paste from Yanbo brand in these special environments, special attention should be paid to its applicability and potential risks.

6、 Improvement suggestions

The following improvement measures can be taken to address the issues mentioned above:
