Name:Knitted Mesh Shielding Tape-Tinned copper
Details:
Knitted Mesh Shielding Tape Tinned copper wire
Knitted Mesh Shielding Tape is a double layered strip of knitted wire mesh providing effective EMI shielding for electrical and electronic cable assemblies . The knitted construction of EMI SHIELDING TAPE maximizes conformability and flexibility while minimizing bulk and weight . Standard EMC SHIELDING TAPE uses Sn/Cu/Fe knitted wire to provide greater physical strength and shielding effectiveness than maybe achieved with other tape materials
APPLICATION INFORMATION
Knitted Mesh Shielding Tape is recommended for EMI shielding , grounding, and static discharge applications. It is particularly effective as a primary or supplementary shield for electronic cables and cable assemblies. The flexibility of Knitted Mesh Shielding Tape permits it to conform to irregular surfaces. EMC Shielding Tape is useful in a broad range of temperatures and environments.
EMI SHIELDING PERFORMANCE
Knitted Mesh Shielding Tape effectiveness has been tested in accordance with Test Method TSETS01 and based upon modified MIL-STD 285. Typical values are given below ;

METHODS OF APPLYING KNITTED MESH SHIELDING TAPE EMC SHIELDING TAPE
Should be wrapped around the cable assembly. Wrap the main cable and terminate the tape before beginning to wrap the cable branch . Start and end all helical wrapping with a minimum of wro overlapping circumferential wraps . At branch connections., start at least 4 in (100mm) before and after branch to assure adequate Knitted Mesh Shielding Tape coverage at the "V" section. Branch connections should not be designed to occur within 4 in (100mm) or each other .
Recommended lead for most applications is 0.50 in. (13mm) , although some additional shielding will be achieved when utilizing a 0.25in(6mm) lead The length of EMC SHIELDING TAPE required for each cable using theres two types of lead wraps can be obtained by referring to Figure 2.
