EMI Shielding Materials for 5G Telecommunication Applications
The fifth generation of cellular networks, 5G, is now the global wireless standard. Previous generations such as 4G operated on low- and mid-band frequencies, whereas 5G can operate on low-, mid-, and high-band frequencies.
5G promises top speeds but carriers need millimeter-wave technology to tap into the high-band frequencies that make it happen. High-band millimeter-wave signals are easily disrupted by buildings, people, and trees among other things, making them less reliable over distances than 4G. They also don’t travel nearly as far as the 4G signals do, requiring more tower density in cities to create stable signals.
Each cell that 5G networks are comprised of is subject to the outside environment and the elements. Like the mailman, these cells are exposed to rain, snow, ice, and heat, and must continue to perform without a hitch. Beyond that, they’re exposed to external signals and need reliable EMI shielding to keep internal parts safe from the outside.
5G technology is only a piece of the telecommunication puzzle that requires reliable EMI shielding, but it makes for a great example. This next-generation technology opens up the gates for innovation and improvements when it comes to things like handheld electronics, driverless cars, and drones.
Despite the ubiquitous need for environmental sealing and EMI shielding, many EMI shielding materials don’t make great environmental seals. Some could get a pass, but many do not. This is why choosing the right EMI shielding material is critical in telecommunication applications – the wrong choice and you’ll wind up with device failure.
Each material has its own set of specs that determine its effectiveness as a seal and shield. If you need some help with that, you can always lean on your manufacturing partner.
Features / Benefits of CHOFORM 5528
CHOFORM 5528 offers a range of features and benefits that make it an ideal choice for telecommunications applications requiring environmental sealing and EMI shielding. One notable advantage is its suitability for densely populated electronics. With its small form factor gasketing solution, this material is specifically designed to fit along narrow walls or complicated geometries, allowing for efficient use in compact electronic devices. By reducing the need for a secondary environmental gasket, CHOFORM 5528 streamlines the assembly process, saving time and resources.
In addition to its applicability in densely populated electronics, CHOFORM 5528 excels in intercompartmental isolation or cavity-to-cavity isolation for signal processing or signal-generating processes. This ensures that there is minimal cross-talk between components, leading to improved performance and reduced interference. Moreover, the material's high EMI shielding requirement, providing 40 dB attenuation between 24 GHz and 77 GHz, guarantees reliable protection against electromagnetic interference.
Another advantage of CHOFORM 5528 is its suitability for uncontrolled environments. Its ability to cure in 24 hours, dependent on the environment, makes it a convenient choice for fast-paced production schedules. Although its adhesion strength is lower than that of heat cure materials, its lightweight nature compensates for it, making it an excellent option for applications where weight is a concern. Additionally, the material's low Shore A hardness ensures a low closure force, allowing for easy installation and maintenance.
Manufactured with Speed and Precision: Selecting the Right FIP Dispensing Partner
When working with premium materials like CHOFORM 5528, the dispensing process is just as critical as the material selection itself. The most advanced EMI shielding material in the world can't perform to specification if it's not properly dispensed with precision and expertise.
Finding the right manufacturing partner for your form-in-place gasket dispensing needs can make the difference between a defense project that fails in the field and one that performs flawlessly under pressure.
Why Partner Selection Matters for FIP Dispensing
FIP gasket dispensing is as much an art as it is a science, with a steep learning curve that can impact your project's timeline and performance. When evaluating potential partners, consider these critical factors:
- Engineering expertise and support throughout the process
- Vertical integration capabilities to reduce lead times and risk
- Quality management systems with defined metrics and goals
- Experience with defense applications and security compliance
At Modus Advanced, we've invested heavily in both the technical capabilities and the engineering talent required to master the FIP dispensing process. With over 10% of our staff being degreed engineers, we provide our defense partners with direct access to technical experts who understand both the materials science and the manufacturing processes required for perfect FIP gasket dispensing.
You Need the Best, Choose Parker Chomerics
Sure, there are a lot of other materials to choose from on the market, but few can stand up to the quality of the materials from Parker Chomerics. Couple their 60+ years of innovation and our 40+ years of engineering excellence here at Modus, and you’ve got yourself a winning combo.
