(1) Electronic component carrier: Tin-plated copper foil can serve as a carrier for electronic components, allowing them to be adhered to the surface of the circuit, thereby reducing the resistance between the electronic components and the substrate.
(2) Shielding function: Tin-plated copper foil can be used to create electromagnetic wave shielding layers, thus shielding against radio wave interference.
(3) Conductivity: Tin-plated copper foil can act as a conductor, carrying current in the circuit.
(4) Corrosion resistance: Tin-plated copper foil resists corrosion, thereby extending the service life of the circuit.
