Copper foil offers conductivity and electromagnetic insulation. PET film provides electrical insulation and high mechanical strength. Copper foil is corrosion-resistant, radiation-resistant, weldable, and offers higher conductivity than aluminum foil. We also offer adhesive-free foil film laminates tailored to your needs.
- PET film protects copper foil from damage and oxidation
- Copper foil provides electrical shielding, while PET film offers insulation
- EMI shielding
- Data transmission cable
RA copper foil and ED copper foil have their respective advantages and disadvantages.
- RA copper foil is purer in terms of copper content.
- RA copper foil offers better overall physical performance compared to electrolytic copper foil.
- Both types of copper foil have nearly identical chemical properties.
- In terms of cost, ED copper foil is usually less expensive due to its simpler manufacturing process and the ease of mass production.
- Typically, RA copper foil is used in the early stages of product manufacturing, but as manufacturing processes mature, ED copper foil is often utilized to reduce costs.
