The corrosion resistance and conductivity of double-sided tinned copper foil and double-sided tinned rolled copper foil are both excellent

 
     Double sided tinned copper foil、 Double sided tinned rolled copperThe corrosion-resistant copper foil has good conductivity, but it is prone to oxidation when exposed to humid air. To solve this problem, a layer of tin, a non oxidizing conductive substance, is plated on the surface of the copper foil (tin is also a conductive metal, but has good stability. It is not easy to oxidize in air, but has high cost and no thin film industry). This can utilize the conductivity of copper without deteriorating the material, and improve the product's performance and service life.
The general process is to electroplate a 2-3u tin layer on both sides of the copper foil Apply conductive adhesive on one side, which can be used in some instant adhesive applications such as high-definition TV data cables, military shielding materials, communication engineering, solar module EMI shielding components, etc. Adhesive: conductive adhesive.
Tin layer thickness: 2-3um on both sides Release material: transparent release film

Double sided tinned copper foil and double-sided tinned rolled copper are usually used to provide good conductivity from the substrate through the adhesive surface to the foil substrate. Suitable for grounding and EMI shielding of electronic devices and components, the tin layer coated has good weldability and improves oxidation resistance and corrosion resistance.

This product will not reduce the shielding effect due to oxidation of the substrate or solder joints when assembled or mounted in electronic devices.

Attachment: The reduction of shielding effect will affect the clarity or purity of sound quality of electronic devices and other external (electromagnetic wave) influences.
