1. Copper Foil Backing:
   • Thickness: 2.6 mil (0.066 mm)
   • Material: Flat copper foil
   • The copper foil serves as the primary shielding material, offering excellent conductivity and effective protection against electromagnetic interference.
2. Adhesive Coating:
   • Thickness: 1.4 mil (0.036 mm)
   • Material: Electrically conductive acrylic pressure-sensitive adhesive
   • The adhesive coating is applied on one side of the copper foil backing. It not only ensures a secure and durable bond but also provides additional electrical conductivity for effective EMI shielding.
3. Liner:
   • The tape comes with a removable liner that protects the adhesive surface before application. This liner makes the installation process convenient and ensures the tape retains its adhesive properties until it is ready to be used.
