Matrix Technology Case Study: Delivering a Complete EMI Shielding Solution for PCB Protection
Overview of the Challenge
A prominent component manufacturer required a comprehensive EMI shielding solution to effectively protect components on a printed circuit board (PCB). The project called for an integrated approach, combining a conductive cover, shielding gasket, and RF absorbing materials into a single, cohesive system.
Design and Technical Requirements
The manufacturer had several critical requirements for this project:
- Supply Chain Management: The vendor needed to oversee the entire supply chain, ensuring seamless coordination from prototype development to full-scale production
- Cost Efficiency: The solution had to be competitive in pricing without compromising on quality or performance
- Global Manufacturing Support: The solution needed to support manufacturing operations in China, requiring robust logistical and production capabilities
- Specialized Materials: The incorporation of CHO-MUTE® 9000 RF absorption material was essential for managing specific electromagnetic interference challenges
Specific Customer Needs
The manufacturer’s primary requirements included:
- Pre-applied EMI Gasket: The EMI gasket needed to be applied directly to the cover to ensure effective shielding.
- Superior EMI Shielding: The solution had to deliver high levels of EMI shielding to protect the PCB components.
- Targeted RF Absorption: RF absorption materials were necessary in specific areas to mitigate interference effectively.
Matrix Technology’s Comprehensive Solution
Matrix Technology responded with a fully integrated EMI shielding solution that addressed all of the customer’s requirements. Our approach included managing the entire supply chain, from the initial prototyping phase in the United States to the final production stage in China. This global coordination ensured that the solution was delivered efficiently and cost-effectively.
We met all performance specifications, providing a low-cost aluminum cover and introducing PREMIER conductive plastic as a potential alternative to further enhance the solution’s versatility. To ensure optimal shielding, we recommended the use of CHOFORM® 5526 form-in-place EMI gaskets, applied with robotic precision to guarantee a secure fit between the cover and the PCB trace.
For RF absorption, we supplied CHO-MUTE® 9000 material with a pressure-sensitive adhesive (PSA), allowing for easy application and effective mitigation of electromagnetic interference where needed.
Conclusion
Matrix Technology successfully delivered a robust and cost-effective EMI shielding solution that met the customer’s stringent requirements. By managing the supply chain across multiple locations and offering innovative material solutions, we ensured the protection and reliability of the PCB components in a demanding environment.
