Description
ATD-CFL-5A is a premium electrograde copper foil tape engineered for EMI/RFI shielding, circuit repair, and electronic prototyping. Made from zero temper annealed copper, this malleable foil conforms easily to irregular surfaces and provides excellent solderability for precise electrical applications.
This version is coated with a high-performance acrylic adhesive, delivering strong long-term bonding without conductivity through the adhesive layer. Ideal for shielding, repairs, and assembly work, this tape is commonly used for transformer coils, cable splices, and circuit modifications. It meets UL 510 specifications and is suitable for use in demanding environments.
⚠️ Note: This version (CFL-5A) does not include conductive particles in the adhesive like CFL-5CA.
