Transparent Blackened Non-Gel Flexible Copper Clad Laminate
Category:
Product Advantages
The transparent blackened, adhesive-free flexible copper-clad film is a copper conductive film whose surface has undergone special treatment. Its key feature lies in the fact that, through a specific processing technique, a uniform and dense black oxide film is formed on the surface of the copper conductive film, thereby significantly enhancing its electrical conductivity, corrosion resistance, and stability.
Product Applications
Transparent flexible antenna, metal mesh touch film, etc.
