Chomerics’ CHO-FOIL tapes arean economical EMI shielding solutionfor a variety of commercial uses.The tapes are available in copper,aluminum, or tinned copper foilbacked with Chomerics’ highlyconductive pressure-sensitiveadhesive*. Typical properties areshown in Table 1 on the next page,and reliability data appears in Table
* Recognized Under the ComponentProgram of Underwriters Laboratories, Inc.
CHO-FAB tape is a corrosionresistant nickel-plated cloth coatedwith Chomerics’ highly conductivepressure-sensitive adhesive*.CHO-FAB tape is extremely strongand lightweight, and has excellentconformability/wrapability to enhanceshielding performance and appear-ance. Use of corrosion resistant nickel-plated cloth and Chomerics’ superiormetal-particle-filled conductive adhesive technology produces atape used in a wide variety of EMIshielding and grounding applications.Typical properties are shown in Table1 on the next page.
Ordering ProcedureRefer to Tables 2 and 3. All CHO-
FOIL and CHO-FAB tapes are avail-able in standard 36 yard (32.9 m)rolls or die-cut custom configura-tions. Call Chomerics’ ApplicationsEngineering Department for assis-tance with a custom configuration.
4 on page 148. CHO-FOIL coppertape is available with a non-conduc-tive adhesive for applications requir-ing surface conductivity only. Anembossed version of CHO-FOIL copper tape is also available, for amore attractive appearance up to 6inches (152 mm) wide. Standardlength rolls and die-cut customshapes can be ordered.
■ Provide a low impedanceconnection between a braidedcable shield and the metalconnector backshell in moldedcables. An effective EMI shieldedassembly can be achievedwithout soldering the tape tothe braid or backshell
■ EMI radiation measurementtroubleshooting, using CHO-FOIL tape to shield ventilationslots or seam gaps
■ Provide electrical continuity inseams of EMI shielded roomsand electronic enclosures
■ Supply electrical contact to surfaces that can’t be solderedto, such as conductive plasticor aluminum
■ EMI shield for cables bywrapping the tape aroundthe cable. An overlap isrecommended
■ ESD shielding■ Provide corrosion-resistant
ground contact points■ Fabric tape available where
weight and flexibility areimportant, such as forwrapping cables
