Faraday electric bike

Faraday Bicycles is a manufacturer of premium-quality electric bikes, or e-bikes. Located below the seat of each Faraday bike is an electronic component box that assists riders with pedaling. With these components being very important to the bike’s core functionality, Faraday needed to make sure the box was properly sealed and protected, which was where GM Nameplate (GMN) came in. The seal had to be waterproof so the bike could be rideable in various weather conditions, such as the rain. It also had to be strong enough so no one could access or tamper with the components inside the box. Finally, vibration had to be minimized within the box so the components wouldn’t be damaged. Therefore, with GMN’s extensive knowledge on adhesive materials and years of experience in producing die-cut components, Faraday asked GMN to help them find the optimal solution for their application.

GMN is a converter partner for Laird Technologies.

Do you need to protect your electronic device from overheating or reduce unwanted EMI noise? Do you need a gap-filling material to enable an electronic connection? If so, GM Nameplate (GMN) has the capabilities and knowledge that will help.

GMN has a strategic partnership with Laird Technologies as a designated converter partner. Laird is an industry leader in providing performance materials for the electronics market. Their product lines include silicone pads, thermal pads, absorbers, and adhesive foams. These materials can be used to reduce heat, reduce static, and create electrical connections.

Thermal pads

Thermal pads are used to transfer heat from a hot surface, such as an integrated circuit (IC) device or LEDs, to a heat sink in order to remove or evacuate heat to prevent damage to parts. Laird designs these pads in a variety of thermal conductivities and softness grades to provide gap filling for many situations. Laird’s Tflex™ thermal pads offer a high degree of “wet out,” or exceptional conformability even to rough surfaces, as well as the ability to transfer heat quickly.

Laird’s Tflex™ products come in silicone or non-silicone pads. Silicone thermal pads are great for electronic applications such as computers, front panel displays, handheld electronics, automotive electronics, and more. Non-silicone pads are ideal for cameras and any product with a lens because they don’t outgas, which refers to the process where trapped gas is released when the pad is heated or placed under a vacuum.  Outgassing from silicone pads produces fogging on a lens, so non-silicone pads are a great alternative while still providing the same qualities as the silicone pads.

Conductive foams

Conductive adhesive foams are compressible foam tapes that are electrically conductive and provide excellent cushioning and recovery properties. These foams are great for gap-filling while maintaining electrical grounding for your product. Laird’s compressible conductive foams also have excellent EMI/RFI properties.

Not only do Laird’s EcoFoam™ conductive adhesive foams provide conductivity along an XY plane, they can provide conductivity though the thickness or depth of the foam (Z direction) as well.

Absorbers

Absorbers are used to reduce or eliminate high frequency or radio frequency noise in electronic systems. GMN offers a variety of Laird’s line of absorbers, NoiseSorb™, that work across all frequencies.

GMN is committed to providing solutions to resolve your product’s specific design challenges with our die-cutting capabilities and strategic partnerships with companies such as Laird.

Die-cut adhesives

Mechanical fasteners and liquid adhesives have been used to fasten and hold two materials together for centuries. However, this does not mean that they are the best or most cost-effective option out there. These traditional practices are quickly being replaced by a superior alternative: die-cut adhesives. In this blog, we will help you understand how strong double-sided tapes and VHB (very high bond tapes) can be, and how they can save your manufacturing process time and money.

Two of the most common examples of die-cut adhesives are double-coated tapes and VHB. Both are products offered by companies such as 3M and can be die-cut and converted by GM Nameplate (GMN).

Problems with mechanical fasteners

Mechanical fasteners such as screws, nuts, bolts, and rivets, are often visible and distracting on a device and prevent it from having a smooth, sleek appearance.

Mechanical fasteners require holes to be drilled in your product. The holes made for these fasteners can accelerate corrosion, and therefore decrease the life of the product. When fasteners are under stress or vibration, they can loosen or slide, which exposes unattractive unpainted areas and speeds up the corrosion process even further.

In addition, if the product is used outdoors and subject to rain or other forms of moisture, the fastening holes can also cause leaking. Leaking can allow moisture and other unwanted materials to enter into your product and cause damage.

Problems with liquid adhesives

During the application process, liquid adhesives can be irritating to the eyes and skin, and produce nauseous fumes. In environments like this, respirators and gloves are often needed during the manufacturing process which can be cumbersome.  

When applying two substrates together with a liquid adhesive, such as metals, the bond line thickness can be inconsistent; this can weaken the strength of the bond, as well as alter the true dimension of the part. Push out or “squeeze out” of adhesive can occur, which creates a mess and adds extra time for unnecessary clean up. Liquid adhesives also need time to dry, which holds up the manufacturing process and causes bottlenecks. Lastly, equipment for dispensing liquid adhesives is very expensive and adds extra manufacturing costs.

Solution: Die-cut adhesives

GMN and 3M provide die-cut solutions that can replace mechanical fasteners and liquid adhesives in many scenarios. VHB and double-coated tapes are generally water-resistant and can provide solutions for gap-filling, bonding irregular surfaces, cushioning and dampening vibration, sealing, attaching and hanging lightweight objects, and providing long-term durable bonds. The viscoelastic properties of the adhesives can help to reduce stress, squeaks, rattles, and noise vibrations as well. These adhesives are a great fit for small electronic devices, metal skins, bonding decorative metals, and assembly of devices such as computers, tablets and cell phones.

Assembly is made quick and easy by just peeling off a few release liners, and attaching the two substrates together. These tapes are highly effective in hot, cold, and even humid conditions. Being U.V. resistant, die-cut adhesives can maintain strength and withstand all outdoor conditions for up to 35 years.

Tapes can also be easily placed in areas where it’s difficult to utilize mechanical fasteners. An example of this is in the placement of a small cooling fan in an electrical device. It is easier and more efficient to use small die-cut pieces of tape such as VHB to fasten the cooling fan in place. This can also help dampen the noise from the fan. 

GMN is a preferred converter for 3M products. Contact GMN to discuss how die-cuts can replace your mechanical fasteners, thus reducing your manufacturing costs, bonding issues, and improving the appearance of your product.
