When inspiration hits like lightning, the result can be a cutting-edge electronics product. From smartphones to HDTV screens to marine navigation systems, electronics manufacturers rely on the thinnest products in 3M’s VHB portfolio to fit into electronic assemblies, places where thick VHBs cannot fit.
Electronic device engineers know space usually isn’t the only challenge. Modern electronics bonding solutions often must address impact resistance, waterproofing, heat resistance, and/or reworkability to create a device with reliable functionality. In addition to overall performance, some surfaces — paints, metals, low surface energy plastics — are hard to bond and require unique acrylic foam tapes such as 3M VHB tape.
When a spark of creativity results in devices optimized for the IoT, 5G, and beyond, specialized VHB tape is often needed as well. This article dives deeper into how pressure sensitive adhesive converters meet the high standards of the electronics industry today and into the future.
Before exploring specific types of thin VHB tape, here’s a quick overview. Even though 3M VHB double sided tape has been available for over 40 years, it remains one of the strongest tapes ever introduced. With industrial power, it can create bonds strong enough to replace screws, rivets, welding, and many other permanent bonding solutions.
What other features make VHB tape one of the world’s most popular pressure sensitive adhesive product lines? VHB tapes absorb stress and shock, have excellent conformability, show a minimal bond line, are chemical- and moisture-resistant, seal out dirt and moisture, and create long-lasting bonds in harsh and demanding environments. Whew!
With these types of capabilities, applications for this adhesive are wide and varied. Some include:
No two jobs are the same. So, 3M developed specific VHB tapes that work under unique conditions. Need tape for a broad range of surfaces, including glass and plastics? Try the “49” product family. How about powder-coated plastics? Go for the “59” family. No matter which tape manufacturer family you choose, you’ll get a fast and easy-to-use permanent bonding method with high strength and long-term durability.
5980 Product Family — Offers 3M’s best balance of properties. Excellent push-out and anti-lift. Delivers impact resistance to meet industry drop test requirements.
Thicknesses
5900 Product Family — Carries high dynamic stress resistance and adhesion to multiple surfaces. Can replace mechanical fasteners or liquid adhesives.
Thicknesses86400 Product Family — Extreme shock drop resistance for lens bonding, as well as better removability. They are used for bonding a wide range of high and low surface energy materials in the electronics industry.
Thicknesses4914 Product Family — The highest holding power for high shear applications, such as bezel bonding. Virtually invisible fastening keeps surfaces smooth.
ThicknessesVHB tape is impressive on its own, but it really takes a pressure-sensitive adhesive converter to die cut thin VHBs and other pressure sensitive adhesives and flexible materials, turning them into usable parts. Using flat bed, rotary, or laser die cutting methods, a converter die cuts materials into custom sizes and shapes.
Choosing an adhesive converter can be tricky. The best ones are full-service converters with experience in flexible material converting, tight-tolerances, automated processes, and the ability to scale rapidly. Ask if your converter is a 3M Preferred Converter, with access to the most innovative adhesives in the world from 3M.
