The aim of Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) shielding and absorbing materials is to provide a defense against unwanted signals from entering or leaving an electronic device. The 3M 1267 1.5"SQ-100 is an example of such a material, and it functions in a variety of different electronic applications and scenarios.

At its most basic fundamental level, the 3M 1267 1.5"SQ-100 is composed of a conductive copper sheet laminated onto a flexible polyethylene terephthalate substrate. This construction ensures that the material has excellent conductivity which, when combined with its superior shielding performance, makes it ideal for use in a variety of electronic applications.

When used in applications such as radio frequency shielding, this material is able to stop the transmission and reception of undesirable radio frequencies without degrading the signal quality of the desired frequencies. It is also very effective at eliminating the transfer of unwanted electromagnetic fields in applications such as low-level micro-circuit and low-frequency antennae shielding.

The 3M 1267 1.5"SQ-100 material is also useful in extending the operating range of low frequency antennas. In this role, it acts as an absorber, effectively attenuating any unwanted signals and allowing the desired signals to be transmitted and received.

Another important application of the 3M 1267 1.5"SQ-100 material is as a noise damper or attenuator. When applied to an electronic device such as an amplifier or radio receiver, it is able to absorb any unwanted noise or interference that may be present, providing a much cleaner signal for both transmission and reception.

In summary, the 3M 1267 1.5"SQ-100 is an excellent example of a RF/EMI shielding and absorbing material. Its conductive copper laminate construction makes it highly effective for a variety of applications including radio frequency shielding, low-frequency antennae shielding, and noise attenuation. This makes it a valuable tool in the fight against unwanted interference in many electronic systems.
