Materials and plating

Common materials used in the construction of Snap-on Mounting Shielding Fingerstrips include:

  • Beryllium-Copper: Known for its excellent electrical conductivity and corrosion resistance, beryllium-copper is a popular choice for EMI shielding applications. It offers a good balance of strength, ductility, and electrical conductivity, making it ideal for both general and specific shielding needs.
  • Stainless Steel: Stainless steel is another commonly used material due to its durability, resistance to corrosion, and good electrical conductivity. It is particularly well-suited for environments where exposure to moisture or chemicals is a concern.
  • Beryllium-Copper Tin Plated: This variant of beryllium-copper is treated with a tin plating to enhance its corrosion resistance further. The tin plating also provides a smoother surface finish, which can be beneficial in certain applications where low friction is desired.
  • Beryllium-Copper Nickel Plated: Similar to the tin-plated version, nickel-plated beryllium-copper offers improved corrosion resistance and a polished appearance. The nickel plating can also contribute to better solderability in electronic assembly processes.
  • Phosphorous Bronze: While not as commonly mentioned as the others, phosphorous bronze is occasionally used due to its good electrical conductivity and resistance to corrosion. It is slightly less strong than beryllium-copper but still finds application in specific shielding requirements.
