Conductive fabric adhesive tapes for electronic shielding

Conductive Cloth Adhesive Tape for PCB Shielding is a specialized tape used in the field of printed circuit board (PCB) manufacturing and electronic device production. It is designed to provide effective electromagnetic interference (EMI) shielding and electrostatic discharge (ESD) protection for PCBs.

Conductive Cloth：The outer layer of the tape is made of conductive cloth, which is usually fabricated by coating or impregnating a fabric substrate with a conductive material such as copper, nickel, or silver. This conductive cloth offers excellent electrical conductivity and electromagnetic shielding properties.

Adhesive Layer：A high - quality adhesive is applied to one side of the conductive cloth to ensure strong adhesion to the surface of the PCB or other components. The adhesive should have good electrical conductivity as well to maintain the continuity of the conductive path. Some adhesives are designed to be thermally conductive, which helps in dissipating heat generated during the operation of electronic devices.

Conductive Cloth Adhesive Tape for PCB Shielding Features

EMI/RFI Shielding – Blocks unwanted electromagnetic and radio frequency interference.

Lightweight & Thin – Adds minimal bulk to PCB assemblies.

Application in PCB Shielding

Shielding of PCB Components：It is commonly used to wrap around individual components on a PCB that are prone to emitting or being affected by electromagnetic interference, such as integrated circuits, transformers, and connectors. By covering these components with the conductive cloth adhesive tape, the electromagnetic fields can be confined, reducing the interference with other nearby components.
Grounding and ESD Protection：The tape is also used to create grounding paths on the PCB. It can be attached to the ground plane of the PCB or connected to the metal chassis of the electronic device to provide a safe and effective way to dissipate electrostatic charges. This helps in preventing ESD events that could potentially damage the electronic components during handling, assembly, and operation.
PCB Edge and Perimeter Shielding：To further enhance the EMI shielding of the entire PCB, the conductive cloth adhesive tape can be applied along the edges and perimeters of the board. This forms a continuous shielding barrier, preventing electromagnetic waves from leaking out or entering the PCB.
