Double sided tinned copper foil is suitable for various application scenarios in electronic devices, such as power sockets, power cords, and connectors

Copper foil is a common electronic component, mainly divided into two types: single-sided tin plating and double-sided tin plating. The following is an introduction to some basic characteristics and parameters of double-sided tin plating on copper foil.

● Single sided tinned copper foilThis copper foil is coated with a layer of tin metal on the surface as an insulation layer, which protects internal components and reduces contact resistance.

● Double sided tinned copper foilThis copper foil is coated with a layer of tin metal and a layer of copper metal on the surface, forming a multifunctional bonding layer. This copper foil has better conductivity and corrosion resistance, which can effectively prevent components from being corroded or damaged.

Double sided tinned copper foil is suitable for various application scenarios in electronic devices, such as power sockets, power cords, connectors, etc. It can provide better protection, reduce current loss caused by contact resistance, and also improve the lifespan and reliability of components.
It should be noted that double-sided tinned copper foil also has some drawbacks, such as the surface not being smooth enough, which affects the contact effect and signal transmission between electronic components. Therefore, when selecting double-sided tinned copper foil, it is necessary to choose and evaluate according to specific circumstances to ensure that it meets application requirements and quality requirements.
