From Laboratory to Breakthrough: KONLIDA's R&D Path in EMI Shielding

The "Action Plan for Stable Growth of Electronic Information Manufacturing Industry from 2025 to 2026" jointly issued by the Ministry of Industry and Information Technology and the State Administration for Market Regulation clearly proposes to accelerate the research and development of new electronic material technologies and strengthen the independent innovation capability of the industrial chain. At the same time, the demand for high-frequency adaptation, lightweight, and low loss of EMI shielding and EMI protection materials in 5G communication and high-end electronic devices continues to upgrade, and 10MHz-10GHz broadband EMI shielding has become the core technical requirement of the industry.

KONLIDA is supported by specialized laboratories, deeply cultivating the research and development of EMI shielding technology, continuously breaking through industry technology bottlenecks, and providing professional EMI protection solutions and core material support for the electronic information industry.

Professional laboratory configuration to solidify the foundation of EMI shielding research and development

KONLIDA regards laboratory construction as the core carrier of technological innovation, creating a full process EMI shielding research and development platform from material research and development to performance verification:

Establish a specialized laboratory for electromagnetic shielding and thermal management, equipped with professional equipment such as spectrum analyzer, thermal conductivity tester, ANSYS thermal simulation system, etc. It can complete comprehensive testing of shielding effectiveness in the 10MHz-10GHz frequency band, reliability verification in high and low temperature environments, and accurately match the testing requirements of 5G and new generation electronic devices for EMI shielding and EMI protection.

Establish a core R&D team consisting of members with over 10 years of experience in EMI material research and development. The team focuses on improving conductive material formulations, optimizing shielding structures, and innovating processes, forming a closed-loop R&D mechanism of "basic research technology breakthrough achievement transformation" to tackle the core challenges of EMI protection.

Establish a sub laboratory for raw material research and development, focusing on independent research and development of core materials such as conductive fabric substrates, silicone cores, and metal coatings. Control material performance from the source and improve the independent supply system of KONLIDA EMI shielding core raw materials.

Equipped with precision die-cutting, hot pressing and other pilot equipment, achieving seamless connection between laboratory research and development and pilot production. It can provide customers with EMI shielding samples in as fast as 4 hours, accelerating the process of technology implementation.

Core technology innovation, strengthening the core capability of EMI protection

Relying on the hardware support of the laboratory and the technical accumulation of the R&D team, KONLIDA has achieved multiple key technological innovations in the field of EMI shielding, greatly improving the effectiveness of EMI protection.

Ultra-thin and wideband material breakthroughs

Significant progress has been made in ultra-thin conductive fabric technology, successfully developing 0.016mm ultra-thin black conductive fabric with resistance controlled within 0.1 ohms, which is superior to the industry's conventional technology level. It is suitable for the installation needs of miniaturization and integration of electronic devices, providing more flexible material choices for EMI protection of precision equipment.

The wideband shielding technology continues to be optimized. In response to the needs of 5G communication, high conductivity and low-pressure conductive foam has been developed, with a shielding effectiveness of over 75dB (10MHz-10GHz), which can effectively block high-frequency electromagnetic interference, improve the problem of attenuation of traditional materials in high-frequency shielding effectiveness, and build a solid core defense line for EMI shielding.

Manufacturing and environmental performance upgrades

We have independently developed automated production equipment and designed a third-generation conductive foam forming and wrapping machine, which overcomes the problem of winding long wrapped products and improves production efficiency by 30%. At the same time, we control the product size tolerance within ± 0.03mm to ensure the installation accuracy of EMI shielding components and guarantee the stability of EMI protection.

Upgraded environmentally friendly material technology, developed halogen-free flame-retardant conductive foam, certified by RoHS and Halogen Free, with a flame retardant level of UL94-V0. While enhancing EMI protection performance, it conforms to the industry trend of green manufacturing under the "dual carbon" goal.

Collaboration between industry, academia and research to broaden the innovation boundary of EMI shielding

KONLIDA breaks the single enterprise R&D model and continues to expand the innovation boundaries of EMI shielding and EMI protection technology through industry–academia–research collaboration.

We will jointly establish a research and development center with the School of Materials Science and Technology of universities, focusing on cutting-edge technologies such as nanocomposites and flexible shielding films, sharing experimental equipment and talent resources, and accelerating the transformation of basic research into the industrial application of EMI shielding.

Deeply connect with the needs of downstream leading enterprises, establish joint laboratories, and develop customized EMI protection solutions based on the electromagnetic environment characteristics of different scenarios such as 3C electronics, new energy vehicles, and 5G base stations, achieving precise matching of "demand-oriented technology research and development scenario application".

Actively participate in industry standard discussions, track international EMC standard trends, integrate KONLIDA's independently developed EMI shielding technology indicators into industry standard proposals, and enhance the company's technical discourse power in the field of EMI protection.

KONLIDA has applied for over 10 EMI related invention patents, established intellectual property barriers for core technologies, and provided legal protection for the market competitiveness of KONLIDA EMI shielding products.
