Application of PET Copper Coated Film in Sensor Manufacturing and Its Effect on Signal Transmission Efficiency

Sensors are an indispensable part of modern information technology systems, especially playing an important role in fields such as smart homes, medical and health monitoring, and environmental monitoring.Advanced Institute (Shenzhen) Technology Co., LtdDedicated to the research and development of advanced sensor materials and their application technologies, PET copper plated film is one of the important innovative achievements. PET copper plated film is composed of a uniform copper layer deposited on a polyester (PET) film substrate, which has excellent conductivity and mechanical stability.

Characteristics and advantages of PET copper plated film

PET copper plated film as a new typeFlexible conductive materialIt has the following significant characteristics:

• Lightweight and flexible: The thickness of PET substrate is generally between 25 μ m and 100 μ m, and after adding a copper layer, the overall thickness remains lightweight and easy to bend, making it suitable for making flexible sensors such as wearable devices.
• High conductivity: The thickness of the copper layer is generally around 1 μ m, which is sufficient to provide good conductivity and ensure efficient signal transmission.
• Cost effectiveness: Compared to other precious metal coating materials,PET copper plated filmThe cost is lower and suitable for large-scale production applications.

Experimental Design and Data Analysis

To verify the performance advantages of PET copper plated film in sensor manufacturing, we designed a series of experiments to test its signal transmission efficiency and compared it with traditional metal lead connection methods.

experimental setup

• Experimental materials: PET copper plated film produced by the advanced institute was selected as the experimental material, with a specification of 50 μ m thick PET substrate and 2 μ m copper layer.
• Testing equipment: Use high-precision signal generators and spectrum analyzers for signal transmission testing.

Test conditions

Use separately in the same temperature and humidity environmentPET copper plated filmConstruct sensor circuits by connecting metal leads in two ways, and then apply different signals with frequencies ranging from 1kHz to 1MHz to record their transmission losses.

data analysis

The experimental results show that the signal transmission loss of sensor circuits constructed using PET copper plated film is significantly lower than that of traditional metal lead connection methods in various frequency bands. Especially in the high frequency range (>100kHz), the advantages of PET copper plated film are more prominent, with an average transmission loss reduction of about 20%.

discuss

The excellent signal transmission efficiency of PET copper plated film is mainly due to its good conductivity and excellent bonding strength with the substrate. In addition, the flexibility of PET copper plated film also allows it to maintain stable conductivity after multiple bends, which is particularly important for applications that require frequent movement or deformation.

In summary, PET copper plated film is an emerging technologyFlexible conductive materialIt has demonstrated enormous potential in sensor manufacturing. Through comparative experiments with traditional materials, we have confirmed that PET copper plated film can effectively improve signal transmission efficiency, especially in high-frequency applications where the effect is significant. In the future, with the advancement of materials science and optimization of production processes, PET copper plated film is expected to play an important role in more fields.
