When introducing the second major milestone in the company's development, Xiao Chao stated firmly, “When the company decided to shift its focus to independent R&D and manufacturing, our goal was clear: our products must achieve domestic substitution. We have always firmly believed that if foreign companies can produce something, we can too.” Thus, we began assembling a talented team and establishing a comprehensive production system. By leveraging the transition from 2G to 3G customer demands, we dedicated ourselves to technological research, accumulation, and refinement. This ultimately culminated in the remarkable achievement of launching our first-generation products into the market. This milestone signifies that Johan has fully attained the capability for independent R&D and possesses formidable strength to compete within the industry."
Since 2016, Johan has entered a phase where opportunities and challenges coexist in its R&D positioning, reaping the benefits of its efforts.

Simultaneously, we faced difficulties stemming from insufficient understanding of material applications, hindering our ability to fully unlock and utilize their potential. Consequently, our existing products lost their competitive edge in the market and could no longer meet evolving customer demands.” Therefore, for the company, increasing investment in R&D innovation, producing products with stronger core competitive advantages, and achieving product transformation and upgrading had become an urgent priority. Consequently, we decisively and wisely chose to recruit more high-caliber talent in this field. While building a robust in-house R&D center, we actively pursued collaborative R&D projects with institutions such as the Shenzhen Institute of Advanced Technology, Shanghai Jiao Tong University, and Southern University of Science and Technology."
To date, Johan has secured multiple Class I intellectual property rights and invention patents. The company has achieved practical applications in research areas such as thermal insulation materials for 5G technology and 3D conformal shielding heat dissipation films for PCBs. Its conductive products have been successively supplied to renowned domestic and international enterprises, laying a solid foundation for Johan products to capture both domestic and global markets.
Forward-thinking vision drives R&D innovation, while core technologies secure our position as a leading enterprise.
For years, “Made in China” has gained global recognition, introducing the world to Chinese products. Yet it's evident that behind this label lies severe product homogenization, a lack of core technologies, and no pricing power. Therefore, R&D innovation, mastering core technologies, and gaining influence are the cornerstones for “Made in China” to stand at the pinnacle of the world. For enterprises, R&D and innovation are the inexhaustible driving force for long-term, sustainable development.
Since its inception, Johan has consistently adhered to “technological innovation as its core driving force,” actively investing in R&D resources to address customers' advanced technical requirements and import substitution needs. Through in-house development and external industry-academia-research collaborations, the company has established comprehensive R&D and simulation testing laboratories (antenna RF simulation/PIM testing/ Third Harmonic Test System/Ultrasonic Welding/Laser Welding/Shielding Effectiveness, etc.), providing the foundation for product development and production. This enables the creation of a series of products featuring advanced technology and core competitiveness.
The innovative conductive foam packaging developed and manufactured by the company (compatible with adhesive bonding, ultrasonic welding, and SMT assembly methods) caused an industry-wide sensation upon its launch and rapidly captured market share. This domestically pioneering product not only addresses a domestic gap but also enables domestic substitution for imported conductive sponge packaging. It utilizes optimally selected conductive films and PU foam with superior resilience, matching different foam densities to varying grounding requirements across locations. It innovatively alters traditional conductivity patterns and offers multiple wrapping methods based on thickness and material selection.
