In today’s fast-paced environment, the use of advanced electronics is far and wide in almost all spheres of life. Today, most electronics gadgets are compact in size, and yet have multiple features and functionalities. This implies the use of several components on a single board which if not placed properly can lead to electromagnetic interference (EMI). This EMI can damage the functioning of the device as a whole or may cause interruptions. It can be a significant threat to the normal operation of these devices. While EMI can be mitigated by accurate designing and layout of a printed circuit board (PCB), using EMI shielding creates a significant aspect. While EMI shields directly serve as a crucial line of defense against interference, they offer other benefits too. This post explores the pivotal role of EMI shielding in electronics manufacturing and how it contributes to the success of the modern electronics landscape.
EMI Shielding: A Reliable Protector of Electronics from EMI
Even today, the role EMI shielding in electronics manufacturing is quite understated. It actually goes way beyond simply mitigating EMI. The use of EMI shields for PCBs serves multiple purposes in electronics manufacturing. Here are some of them.
- Protection of Sensitive Components from EMI: Printed circuit boards have several types of sensitive components mounted on them, such as sensitive microprocessors, sensors, and communication modules. These components are susceptible to electromagnetic interference. PCB EMI shields suppress EMI and form a physical barrier, thus safeguarding the functionality and longevity of these components, and in turn the device.
- Compliance with Regulatory and Industry Standards: Manufacturers need to adhere to various industry standards and legal compliances related to electromagnetic compatibility (EMC). Non-compliance can result in costly product recalls as well as legal implications, while also damaging the manufacturer’s credibility and reputation. The use of EMI shielding is a fundamental aspect in eliminating these issues.
- Enhanced Product Quality: By using the right board level EMI shields, you can easily prevent EMI-induced malfunctions and signal disruptions. This will subsequently enhance the performance, reliability, and longevity of the final product. Choosing PCB EMI shields with the right thickness and dimensions go a long way in enhancing the overall product functionality and quality.
- Supporting Global Connectivity: With the ever-expanding network of wireless and IoT devices, electronic products must operate seamlessly within crowded electromagnetic spectrums. EMI shielding ensures that these devices can communicate without interference, promoting global connectivity.
Varied Range of EMI Shielding Tools Used
There are various tools and materials used to prevent EMI at board level. Here are some of them.
While many businesses and electronics manufacturers are already using some of the other type of board level shielding tool, this many not be enough to mitigate EMI and reap other benefit too. PCB shields as a market segment of electronics manufacturing is the unsung hero, silently working in the background to ensure that our devices perform reliably and without interruption. However, it is crucial to use the right type of board level EMI shields such as the ones made of plasticized metal. They are customizable and hence better fit the boards, covering just the required areas and leaving space for ventilation and heat dissipation. This not only helps suppress EMI but also enhances the overall product quality. Considering the significance of plasticized metal EMI shields, ensure you source them from known manufacturers and suppliers. XGR Technologies offers SnapShot® EMI shields that not only meet the US EMC standards but offer several benefits. They are made from a thin polyetherimide film on the interior and have a tin coating on the exterior surfaces. These lightweight and flexible EMI shields reduce electromagnetic coupling.
