When choosing conductive cloth, you need to consider the following key factors:
Conductive performance: The core indicator of conductive cloth is conductivity, which reflects the conductive ability of conductive cloth per unit length. The better the conductive performance of the conductive cloth, the higher the current transmission efficiency, which is more valuable in various applications.
Resistance value: The resistance value indicates the resistance of the conductive cloth per unit area. In applications where current needs to be precisely controlled, it is more appropriate to choose conductive cloth with a smaller resistance value, because such conductive cloth is more conducive to the transmission of current.
Tensile strength: Tensile strength determines the maximum tensile force that the conductive cloth can withstand when subjected to tension, which in turn affects its service life and scope of use.
Breathability: In application scenarios where it comes into contact with electronic components and other materials, good breathability can ensure the normal working state of the components.
Temperature range: Different conductive cloth materials have different temperature ranges. When choosing, you must consider their application environment to ensure that the selected conductive cloth can adapt to specific temperature conditions.
Shielding effect: The shielding effect depends on the conductive continuity and surface smoothness of the shielding body. A good quality conductive cloth has a continuous coating, a smooth surface, and is usually silver.
Environmental protection: Choose conductive cloth that meets environmental protection requirements and ensure that its materials and processing processes do not contain harmful substances.
Thickness and color: The commonly used conductive cloth is 0.12mm thick and has colors such as black and gray. Black conductive cloth is usually specially treated, such as tinning.
Appearance and quality inspection: Check the appearance of the conductive cloth for copper leakage, powder loss, etc., and ensure that its thickness, resistance, viscosity, tensile strength and other indicators meet the requirements.
Application scenario: Choose the appropriate type of conductive cloth according to the specific application scenario. For example, high-power and very sensitive instruments require a high level of shielding effect, while medium-level electromagnetic shielding can choose conductive cloth with medium shielding value.
