1. Choose the right material
Use highly conductive metals: such as copper, aluminum, etc. Copper has excellent conductivity. Using it as the main material or part of the material of the screw can significantly improve the conductivity. Aluminum also has good conductivity, and it is light and corrosion-resistant, which is suitable for occasions where conductivity and weight are required. For example, in the shell connection of some electronic equipment, the use of copper or aluminum Hex Head Drilling Screw can better conduct static electricity or serve as a grounding connection.
Use special alloys: such as nickel-copper alloy, which has good conductivity and corrosion resistance. In some specific electrical or electronic applications, it can meet other performance requirements while ensuring a certain conductivity.
2. Optimize structural design
Built-in conductive core: A copper core or other conductive material can be set inside the screw as the core part, so that the current is mainly conducted through the copper core, thereby improving the conductivity of the entire screw. Just like in some special conductive self-tapping screw designs, the conductivity is enhanced by setting a copper core inside the screw body.
Increase the conductive contact surface: Special design is made for the head and tail of the screw, such as adding protrusions, planes or adopting special contact structures, so that the screw has a larger conductive contact surface with the connecting parts after installation, reducing contact resistance and improving the conductive effect.
3. Surface treatment improvement
Highly conductive metal plating: The surface of the screw is electroplated, such as silver plating, gold plating, etc. Silver and gold have very good conductivity. By electroplating, a thin layer of silver or gold is formed on the surface of the screw, which can greatly improve its surface conductivity without changing the overall material and structure of the screw. It is often used in some precision electronic equipment with extremely high conductivity requirements.
Avoid insulating coating: If the screw originally has an insulating coating, such as spray paint, plastic coating, etc., these insulating coatings should be removed in applications that require conductivity to ensure the conductivity of the screw.
4. Optimization of installation and use environment
Ensure good contact: When installing the screw, ensure that the screw fits tightly with the connecting part to avoid looseness, gaps or oxide layers that affect conductivity. An appropriate torque wrench can be used to control the tightening force to ensure the reliability and conductivity of the connection.
Control the use environment: Try to avoid using the screws in a humid, corrosive or oily environment that may affect the conductivity. If it cannot be avoided, take appropriate protective measures, such as sealing, moisture-proofing, and corrosion-proofing, to reduce the impact of environmental factors on the conductivity of the screws.
