How to evaluate the performance of PI gold-plated film in specific environments?

Evaluating the performance of PI gold plating film under extreme conditions such as low temperature and vacuum is key to ensuring its reliability in high-tech applications. This article will explorePI gold-plated filmPerformance evaluation methods in these environments, and mention the professional contribution of Advanced Institute (Shenzhen) Technology Co., Ltd. in this field.

Performance evaluation under low temperature environment

1. Low temperature resistance test: The low temperature resistance of PI gold-plated film is usually tested through high and low temperature test chambers. The sample is kept at a set low temperature for a certain period of time, and then the changes in its physical and electrical properties are observed. This is crucial for applications in aerospace and extremely cold regions.

2. Conductivity testing: At low temperatures, the electrical resistivity of the material may change. Use the four point probe method to test the resistivity of PI gold plating film to evaluate whether its conductivity is affected.

3. Mechanical performance testing: Low temperatures may affect the flexibility and impact resistance of materials. Evaluate the mechanical performance changes of PI gold-plated film through tensile and impact tests.

Performance evaluation in vacuum environment

1. Vacuum thermal stability test: In a vacuum environment, the thermal stability of materials is an important indicator. Evaluate the stability and performance changes of PI gold plating film by exposing it to a simulated vacuum environment in space and heating it to a specific temperature.

2. Electromagnetic shielding effectiveness test:PI gold-plated filmThe electromagnetic shielding effectiveness (SE) is a key indicator for measuring its ability to attenuate electromagnetic waves. In a vacuum environment, a vector network analyzer (VNA) is used to measure the reflectivity, absorptivity, and transmittance of PI gold plating film at different frequencies, and the SE value is calculated comprehensively.

3. Antioxidant performance testing: In a vacuum environment, the antioxidant performance of materials is the key to evaluating their long-term stability. Conduct experiments using a high-temperature oxidation furnace to measure the oxidation rate of PI gold plating film and evaluate its antioxidant performance.
