Product parameters
- Substrate: Polyimide (PI) is used, which is an organic polymer material with extremely high heat resistance and mechanical strength.
- Coating: A uniform layer of pure copper metal with a thickness of 1-5 microns ensures good conductivity.
- Thickness range: from 25 microns to 75 microns, can be customized according to specific customer requirements.
- Width specification: up to 1200 millimeters, suitable for production lines of various sizes.
- Roll length: The length of a single roll can reach 5000 meters, making it convenient for large-scale production and use.
- Tensile strength:> 170MPa, exhibiting excellent mechanical stability.
- Dielectric constant: about 3.8, suitable for high-frequency signal transmission applications.
- Temperature resistance: Long term use temperature range -269 ℃ to 260 ℃, short-term can withstand high temperatures up to 400 ℃.
Production process
The manufacturing process of PI copper plated film strictly follows the ISO quality management system standard, mainly divided into the following steps:
- Raw material preparation: Select high-quality PI film as the base material and ensure that its surface is smooth and defect free.
- Surface treatment: Pre treat the PI film by chemical or physical methods to improve its adhesion with the copper layer.
- Vacuum Copper Plating: Utilizing in a Vacuum EnvironmentPhysical vapor deposition technology(PVD) orChemical vapor deposition technology（CVD）， Uniformly deposit copper on the surface of the PI film.
- Quality inspection: After completing copper plating, multiple tests are required, including appearance inspection, thickness measurement, conductivity testing, etc., to ensure that the product quality meets the standards.
Product advantages and features
- Excellent electrical performance: Due to the use of high-purity copper as the conductive layer, the PI copper plated film has extremely low resistivity and excellent performanceElectromagnetic shielding effect.
- High strength and flexibility: The PI material itself has excellent tensile strength, coupled with the reinforcing effect of the copper layer, allowing the product to withstand greater external forces while maintaining good flexibility.
- Wide adaptability to temperature range: Whether in extreme cold or high temperature environments, PI copper plating film can maintain a stable working state and is not prone to deformation or failure.
- Environmental safety: Strictly control the use of harmful substances during the production process, in compliance with international environmental standards such as RoHS.
