RF (Radio Frequency) and EMI (Electromagnetic Interference) shielding and absorption materials are critically important in the development and implementation of modern consumer electronics. 3M\'s CN3190 1.5"SQ-100 is an example of such a product, and is suitable for a wide range of applications in the consumer electronics industry.

The CN3190 1.5"SQ-100 is a high performance adhesive-backed aluminum foil tape with a strong permanent acrylic adhesive. It provides excellent shielding performance and protection against RF and EMI interference with minimal intrusion into the surrounding environment. The adhesive provides excellent adhesion to most substrates and does not need to be reapplied after exposure to harsh conditions.

The CN3190 1.5"SQ-100 is designed to provide electromagnetic shielding for a variety of consumer electronic applications. Its adhesive backing allows for easy application on most substrates including metal, plastic, and paper. The tape also resists high temperatures, extreme oxidation, and abrasion. It is also dust, grease, and solvent resistant. The tape can be applied to flat or contoured surfaces and provides complete coverage.

The CN3190 1.5"SQ-100 has several applications in the consumer electronics industry. It is used for both shielding and absorbing RF and EMI emissions, including radio and microwave signals. The adhesive back allows for easy application around the entire device and ensures a secure bond with the device. It is also used to reduce both conducted and radiated signals, thus reducing EMI noise and potential interference with other electronic equipment.

The working principle of the CN3190 1.5"SQ-100 is simple. It is designed to provide an electrically conductive barrier to shield and absorb EMI emissions. The aluminum foil element acts as the shielding layer and the adhesive acts as the contact layer. The adhesive is designed to provide a secure bond with the substrate which enables the foil to absorb and shield the susceptible electronic components from the interference.

In conclusion, 3M\'s CN3190 1.5"SQ-100 is an important product in RF and EMI shielding and absorption materials. It provides excellent adhesion to most substrates and has a wide range of uses in the consumer electronics industry. It is also easy to apply and provides complete coverage with minimal intrusion. Finally, the working principle is simple and effective, ensuring a secure bond between the adhesive and substrate, allowing for effective EMI shielding and absorption.
