Contacts, Fingerstock, and Gaskets provide connectivity, shielding, and protection against electromagnetic interference (EMI) and environmental factors. Contacts refer to electrical connectors used for signal transmission, ranging from coaxial connectors to board-to-board connectors. Fingerstock, also known as EMI gaskets or shielding gaskets, are flexible metal strips used to create electrical contact between surfaces while providing EMI shielding. Gaskets are seals used to prevent moisture, dust, and EMI leakage in electronic enclosures, ensuring environmental protection and signal integrity. Basic connectors and gaskets suitable for standard applications can be affordable. However, specialized connectors with high-frequency capabilities, precision tolerances, and enhanced shielding properties may command higher prices. When purchasing these components, define the specific application requirements such as frequency range, signal integrity, environmental conditions, and EMI shielding needs to select components with suitable specifications. Choose connectors with compatible interfaces (SMA, BNC, N-Type, etc.) and gaskets with appropriate compression, conductivity, and sealing properties for optimal performance. Additionally, consider factors like material compatibility, mechanical durability, and assembly requirements (e.g., soldering, crimping, compression) for seamless integration into your RF and Wireless systems.
