EMI Shielding Foil and Fabric Tape with Conductive Adhesive
Parker Chomerics CHO-FOIL® metal foil tapes provide an economical and highly effective solution for applications demanding superior electrical conductivity across substrates. These tapes are designed to create low impedance connections between braided cable shields and metal connector backshells in molded cables, offering a reliable and efficient alternative to traditional methods.
One of the key advantages of CHO-FOIL tapes is their use of a highly conductive pressure-sensitive acrylic adhesive (PSA). This innovative adhesive eliminates the need for soldering, simplifying the assembly process and ensuring effective shielded cable assemblies. The PSA contains uniformly distributed, oxidation-resistant conductive particles, which guarantee very low resistance through the tape, enhancing the electrical performance of the assembly.
In practical applications, wrapping a cable assembly with CHO-FOIL tape using a slight overlap can quickly create a highly efficient prototype cable shielding system. This makes it an ideal choice for rapid development and testing phases. Additionally, CHO-FOIL tape can be used to seal EMI shielded room seams and other shielded test enclosure setups, ensuring electrical continuity and significantly enhancing shielding effectiveness.
For scenarios requiring double-sided conductivity, the CHO-FOIL tape offers a variant with double-sided conductive adhesive. This ensures leak-free seams and reliable electrical connections, further broadening the tape’s utility in various complex applications. It also provides electrically conductive mating flanges and corrosion-resistant grounding areas, making it a versatile tool in the engineer’s toolkit.
For applications where lighter weight and greater flexibility are paramount, Parker Chomerics offers CHO-FAB™ fabric tape as an excellent alternative. CHO-FAB™ tape provides superior shielding and corrosion resistance, combined with high conformability, strength, and lightweight characteristics. Unlike metal foil tapes, CHO-FAB™ tape lacks sharp edges, making it safer and more suitable for shielded cables, especially in environments where flexibility and ease of handling are critical.
Parker Chomerics CHO-FOIL® and CHO-FAB™ tapes deliver outstanding benefits for a wide range of applications. Whether for creating low impedance connections, enhancing shielding effectiveness, or providing flexible, lightweight solutions, these tapes offer unparalleled performance and reliability. Their innovative design and high-quality materials make them the preferred choice for engineers seeking to optimize electrical conductivity and shielding in their projects.
