In the modern era of semiconductor manufacturing and SMT (Surface Mount Technology), the "Rubber Ka Cover" (high-performance cover tape) serves as the critical protection layer for sensitive electronic components. As the global demand for miniaturized devices peaks, the industry has transitioned from simple adhesive barriers to advanced functional materials that provide anti-static, heat-resistant, and chemically stable environments during high-speed automated assembly.
We are witnessing a significant shift toward precision engineering in carrier tape systems. The trend is moving towards lower peel-force variability and ultra-high transparency. Manufacturers are now integrating AI-driven quality control to ensure that every millimeter of cover tape meets the rigorous standards required by high-density chip packaging and automotive electronics where failure is not an option.
Global procurement teams are no longer just looking for suppliers; they are looking for strategic partners. The demand is focused on factories that offer consistent batch-to-batch quality, ISO-certified production environments, and the ability to customize tapes for specific carrier materials like PS, PC, or PET. Stability in supply chains and environmental compliance (RoHS/REACH) are now mandatory prerequisites.
Established in June 2007, Jiangsu Yongjia Electronic Materials Co., Ltd. has dedicated 18 years to the rigorous field of functional tape manufacturing. Located in the strategic industrial hub of Nantong, our facility spans 16,000 square meters, housing advanced R&D laboratories and scientifically planned production workshops.
As a specialized manufacturer, we focus on the core track of functional tapes for the electronics industry. Our expertise covers the entire lifecycle of tape production: from initial chemical R&D and precision coating to rigorous sales and comprehensive after-sales service. Our commitment to being "people-oriented" ensures that talent and technology drive our pursuit of zero-defect quality.

The manufacturing ecosystem in China, specifically in the Nantong industrial region, offers unparalleled advantages for global electronic material procurement. At Jiangsu Yongjia, we leverage these advantages to provide high-end solutions at competitive scales.
Our laboratories are equipped to simulate various SMT environments, allowing us to test heat-seal and self-adhesive tapes against diverse carrier tape materials. This ensures that our "Rubber Ka Cover" products maintain stable aging performance across different climates globally.
Unlike trading companies, we manage the entire process from raw material chemical mixing to final slitting. This vertical integration allows for customized width, thickness, and adhesive strength according to specific client equipment requirements.
Our production lines are optimized for clean-room standards, minimizing contamination which is crucial for semiconductor packaging. Our series of products—from standard high-temperature tapes to flame-retardant acetate cloth tapes—undergo rigorous QC checks.
Technical Excellence: Our heat-seal cover tapes are designed with precise chemical formulations to prevent "blocking" or adhesive residue, ensuring that the components are delivered in pristine condition to the pick-and-place machines. The enhanced high-temperature series is specifically developed for aerospace and high-end industrial applications where thermal stability up to 200°C+ is often required.
Consistently adhering to the core principle of innovation, we provide a full spectrum of industrial tape products designed for durability and performance.
Optimized for PS and PC carrier tapes with consistent peel force and zero static interference.
Designed for easy application without heat, perfect for sensitive components and fast-turnaround packaging.
