EMI Shielding Techniques

Laird Technologies employs various EMI shielding techniques to achieve optimal performance and meet specific application requirements. Each technique offers unique advantages and disadvantages, influencing the selection based on factors such as cost, effectiveness, and ease of implementation.

• Enclosure Shielding: This technique involves enclosing the sensitive electronic device within a conductive enclosure, effectively blocking electromagnetic interference. Enclosures can be made from various materials, including sheet metal, conductive polymers, and mesh. Enclosure shielding offers high shielding effectiveness but can be bulky and may limit access to internal components.
• Cable Shielding: Shielding cables that connect to sensitive electronic devices is crucial to prevent electromagnetic interference from traveling along the cables. Cable shielding can be achieved using various methods, including braided shields, foil shields, and conductive polymer sheaths. Cable shielding offers high shielding effectiveness and is essential for maintaining signal integrity in sensitive electronic systems.
• Gasket Shielding: Gaskets made from conductive materials can be used to seal gaps and seams in enclosures, preventing electromagnetic interference from entering or escaping. Conductive gaskets are commonly used in applications where environmental sealing is also required, such as in automotive and industrial equipment.
• Coating Shielding: Applying a conductive coating to the surface of a device or component can effectively block electromagnetic interference. Conductive coatings can be applied using various techniques, including spraying, dipping, and electroplating. Coating shielding offers a cost-effective and flexible approach to EMI shielding, particularly for complex geometries.
• Absorption Shielding: This technique involves using materials that absorb electromagnetic energy, reducing the amount of interference that reaches the sensitive electronic device. Magnetic materials like ferrites are commonly used for absorption shielding, particularly at lower frequencies. Absorption shielding is effective at reducing the intensity of electromagnetic interference, but it may not completely eliminate it.
