Electromagnetic shielding technology plays a crucial role in the operation of modern electronic devices. Aluminum foil tape, as an economical and convenient electromagnetic shielding material, is widely used in various occasions where electromagnetic interference prevention is required. This article will explore the electromagnetic shielding effectiveness of aluminum foil tape at different frequencies and compare it with the one developed by Advanced Institute (Shenzhen) Technology Co., LtdYanbo brand aluminum foil tapeRelated data.

Electromagnetic shielding principle of aluminum foil tape

Aluminum foil tape, through its surface aluminum foil layer, can effectivelyShielding electromagnetic wavesWhen electromagnetic waves propagate to the surface of aluminum foil, aluminum foil, as a conductive material, reflects the energy of electromagnetic waves, thereby reducing the energy of electromagnetic waves that penetrate the aluminum foil and causing it to attenuate. Aluminum foil tape can be attached to the equipment that needs to be shielded, forming a tight shielding body to prevent interference signals from entering the interior of the equipment.

Electromagnetic shielding effectiveness at different frequencies

The electromagnetic shielding effectiveness of aluminum foil tape varies at different frequencies. Generally speaking, aluminum foil tape has a good shielding effect on high-frequency electromagnetic waves, but its shielding effectiveness may decrease in the low-frequency range.

1. Shielding effectiveness of aluminum foil tape in high frequency range

In the high frequency range (such as 1GHz to 40GHz), aluminum foil tape exhibits excellent shielding effect. The experimental data shows that,Aluminum TapeIn this frequency band, the electromagnetic radiation intensity can be significantly reduced, and the shielding effect usually reaches tens of dB or more. For example, at 10GHz, aluminum foil tape may achieve shielding effectiveness of up to 100dB or more.

2. Shielding effectiveness of aluminum foil tape in low frequency range

In the low frequency range (such as 10kHz to 1GHz), although the shielding effectiveness of aluminum foil tape is not as good as in the high frequency range, it still has a certain shielding effect. Experimental data shows that within this frequency band, the shielding effect of aluminum foil tape is usually between 60dB and 80dB. Although it has decreased compared to the high frequency band, for many electronic devices, this shielding effectiveness is still sufficient to prevent electromagnetic interference.
