Changes in conductivity of embossed copper foil tape at different temperatures

Embossed copper foil tape, as a high-performance material, has been widely used in the electronics industry. It has become an indispensable part of modern electronic devices due to its high conductivity and electromagnetic shielding effectiveness. This article will explore the changes in conductivity of embossed copper foil tape at different temperatures, with a particular focus on the performance of Advanced Institute (Shenzhen) Technology Co., LtdYanbo brand embossed copper foil tapeFor example, analyze in detail the trend of changes in its conductivity performance.

Basic characteristics of embossed copper foil tape

The embossed copper foil tape is mainly composed of copper foil and pressure-sensitive adhesive, with a purity of usually over 99.98%. The substrate thickness is between 0.018mm and 0.05mm, and the adhesive thickness is about 0.035mm to 0.04mm. These parameters ensure that the embossed copper foil tape has a low electrical resistivity, thereby ensuring good conductivity. The Yanbo brand embossed copper foil tape performs particularly well in this regard, with conductivity close to the standard conductivity of copper (5.8 × 10 ^ 7 S/m).

The Effect of Temperature on Conductivity

Temperature is one of the important factors affecting the conductivity of materials. As the temperature increases, the atomic vibrations inside the material intensify, leading to an increase in electron scattering and an increase in electrical resistivity, resulting in a decrease in conductivity. On the contrary, as the temperature decreases, atomic vibrations weaken and conductivity improves.

In order to conduct a detailed analysis of the changes in the conductivity of the embossed copper foil tape of Yanbo brand at different temperatures, we conducted a series of experiments. The experiment used the four probe method and direct current resistance method to measureEmbossed copper foil tapeCalculate its electrical conductivity based on its resistivity.

• At room temperature (25 ℃): Under room temperature conditions, the resistance of Yanbo brand embossed copper foil tape is low, and its conductivity is excellent. The test results show that its resistivity is about 1.2 × 10 ^ -8 Ω· m, and its conductivity is close to the standard value of copper.

• High temperature (100 ℃): When the temperature rises to 100 ℃, the electrical resistivity of the Yanbo brand embossed copper foil tape increases, and the conductivity slightly decreases. The test results show that the resistivity is about 1.5 × 10 ^ -8 Ω· m, and the conductivity has slightly decreased, but still maintains high conductivity.

• Low temperature (-20 ℃): Under low temperature conditions, the resistivity of Yanbo brand embossed copper foil tape is further reduced, and its conductivity is improved. The test results show that the resistivity is about 1.0 × 10 ^ -8 Ω· m, and the conductivity is higher than the value under normal temperature conditions.

Experimental results

From the experimental results, it can be seen that the conductivity of Yanbo brand embossed copper foil tape shows a certain variation pattern at different temperatures. As the temperature increases, the resistivity increases and the conductivity decreases; As the temperature decreases, the resistivity decreases and the conductivity improves. However, even under high temperature conditions, the conductivity of Yanbo brand embossed copper foil tape still maintains a high level, thanks to its high purity and excellent manufacturing process.
