This conductivity allows the tape to act as a Faraday cage, diverting electromagnetic waves away from the protected components and preventing their penetration into the circuitry

The mechanism by which PI tape provides EMI/RFI shielding is based on the principle of electromagnetic wave reflection and absorption. When an electromagnetic wave encounters the conductive surface of the PI tape, a portion of the wave is reflected back into the source, while the remaining energy is absorbed by the tape's conductive layers and dissipated as heat

. This dual action of reflection and absorption ensures a high level of shielding effectiveness, even in environments with strong electromagnetic fields. Furthermore, the flexibility and conformability of PI tape allow it to be applied to irregular surfaces and tight spaces, providing complete coverage and minimizing the risk of leakage points that could compromise shielding performance

The importance of effective signal shielding in integrated electronics cannot be overstated. With the increasing miniaturization and integration of electronic components, the susceptibility to EMI and RFI has also increased. PI tape's ability to provide reliable shielding while maintaining the mechanical and thermal integrity of the package is essential for ensuring the stable operation of electronic devices in a wide range of applications
