Tinned copper foil usually consists of copper and tin. Among them, copper is the main component, accounting for about 95%; tin is an auxiliary component, accounting for about 5%. The specific composition of tinned copper foil varies with the production process and material selection.
Tin-plated copper foil is a thin layer of metal tin plated on the surface of copper and copper alloys to increase its corrosion resistance and improve processability. It has excellent corrosion resistance, welding and forming properties.
Tinned copper foil is usually composed of copper and tin
1. Tinned copper foil has many functional characteristics, including:
(1) Electronic component carrier: tinned copper foil can be used as a carrier for electronic components, and the electronic components in the circuit are pasted on the surface, thereby reducing the resistance between the electronic components and the substrate.
(2) Shielding function: Tinned copper foil can be used to make electromagnetic wave shielding layer, so as to shield out the interference of radio waves.
(3) Conductive function: Tinned copper foil can be used as a conductor to transmit current in the circuit.
(4) Corrosion resistance: Tinned copper foil can resist corrosion, thereby prolonging the service life of the circuit.
