What is the direction of innovative design for 5G applications?
3M ™ VHB ™ The adhesive tape is composed of fully closed cell polyacrylic acid ester, which has strong resistance to damage from heat, ultraviolet radiation, water, and chemical reagents. The special overall viscoelasticity of the adhesive tape makes it less prone to stress concentration.
VHB ™ The tape is entirely composed of polyacrylate, which has strong resistance to heat, ultraviolet radiation, and chemical damage.
3M uses unique solvent-free manufacturing technology to produce polyacrylate double-sided foam tape, which differs greatly from common foam tape in VHB ™ The foam core material and surface adhesive are all composed of polyacrylate viscoelastic materials, which can be vividly called "solid glue". This special structure endows the tape with special overall viscoelasticity, and the tape as a whole can effectively dissipate the stress inside the adhesive joint through the mechanical relaxation of the tape, thereby effectively protecting the adhesive line.
VHB ™ The foam core of the tape is a 100% fully closed cell structure that prevents water and air from passing through.
Except for thick VHB ™， Thin double-sided tape with a 100MP adhesive system is also used in 5G antennas and base stations. The PCBA inside the 5G RF device is bonded to the metal panel using F9469PC transfer adhesive film, which is a transparent pure double-sided adhesive with good initial adhesion, a thickness of 0.125mm, long-term temperature resistance of 149 ° C, and short-term temperature resistance of 260 ° C. It is suitable for bonding metal materials and has extremely high peel strength, excellent stability, and high bonding performance.
3690E+is a bright white vinyl label that can withstand harsh environments including ultraviolet radiation, extreme temperatures, and solvents, with excellent moisture and weather resistance. Thinner thickness and flexibility, able to fit small diameter and complex surfaces; Can withstand outdoor use for 5 years under certain conditions.
The thickness of the surface material is 51um, and the temperature resistance range is -60 ℃~150 ℃; The adhesive system is 320 high toughness acrylic adhesive, which can firmly adhere to various high and low surfaces and be attached to objects;
Obtained UL certification (document MH11410) and CSA certification (document 099316).
The product also has a silver version (product grade: 3698E+) available for selection, which meets the appearance requirements of 5G devices for labels.
Multiple communication filters, 5G communication connectors, line equipment, sensors, etc. use DP190 for precision encapsulation.

For 5G equipment power supplies and server power supplies, 3M can provide professional-grade electrical insulation protection solutions. Whether for electronic transformer interlayer protection, barrier applications, FPC flexible insulation, or AC/DC and DC/DC power conversion equipment, 3M offers highly reliable insulation solutions with polyester and polyimide substrates, as well as professional solutions for internal wire harness management and EMC/EMI protection.
3M transparent conductive film attaches nearly invisible metal wiring in ultra-fine mesh form onto transparent film, combining low sheet resistance with high visible light transmittance. Suitable for invisible antenna arrays in various 5G scenarios, solving antenna installation space limitations.
3M absorbing materials cover the full 5G spectrum. Millimeter wave absorbers also provide both wave absorption and thermal conductivity functions, with high absorption efficiency and extremely low echo reflection, suitable for electromagnetic noise suppression in 5G antenna RF devices and optical fiber transceivers.
3M glass microsphere products have extremely low dielectric constants and can be added to most resin materials to reduce dielectric properties, meeting 5G high-frequency communication material requirements and reducing signal loss.
3M printed decorative film solutions can be used for 5G base station antenna beautification. The film has extremely low RF loss, anti-stain surface design, and micro air channel adhesive structure, which does not affect 5G signals while simplifying installation, allowing various 5G antennas to blend with the environment for easier deployment.
3M diversified thermal material solutions include thermal conductive tape, non-silicone thermal pads, thermal structural adhesives, and non-silicone thermal gels, meeting diverse product design needs. They reduce contact thermal resistance caused by processing tolerances, improve heat transfer efficiency, prevent silicone contamination, and extend product lifespan.
3M also leads the development of automotive insulation films in the 5G era. Through material technology innovation, it perfectly solves the signal blocking problem caused by metallic and magnetron sputtered films, while addressing the pain points of traditional window films that cannot efficiently and durably insulate heat. All 3M automotive insulation films are non-metallic with no metal content, not blocking in-vehicle 5G, GPS, Bluetooth and ETC signals. In the 5G IoT era, it provides a more comfortable and elegant solution for drivers.
