High-reliability functional tapes engineered for automated surface-mount technology (SMT), carrier tape sealing, and high-temperature electrical insulation.
Jiangsu Yongjia Electronic Materials Co., Ltd. was registered and established in June 2007. After eighteen years of deep cultivation in the field of electronic materials, the company has developed into a comprehensive service provider of functional tape products with considerable influence across global semiconductor and electronics manufacturing hubs. Located in the vibrant industrial environment of Nantong, Jiangsu, the company covers a state-of-the-art manufacturing campus of 16,000 square meters, with a built facility area of 9,000 square meters. Its scientifically planned production workshops, Class 10,000 cleanroom R&D laboratories, and automated testing hubs lay a rock-solid foundation for zero-defect production output.
How advanced polymer synthesis, nano-scale ESD coatings, and thermal stability matrices are transforming semiconductor micro-packaging and SMT carrier assembly.
Modern ultra-fine SMT packaging demands strict electrostatic discharge control. Advanced cover tapes integrate conductive polymer nano-layers maintaining a consistent surface resistivity between 106 to 109 Ω/sq, preventing triboelectric charge buildup during high-speed feeder unwinding (up to 120 meters/minute).
Peel force consistency is the cornerstone of zero-downtime component placement. By engineering custom acrylic and silicone pressure-sensitive adhesive (PSA) matrices alongside temperature-stable heat-seal coatings, peel force standard deviation is constrained within ±0.05 N (tested under ASTM D3330 / EIA-481 standards).
Aligned with global ESG initiatives, the next generation of PET and acetate base films utilizes solvent-free co-extrusion technology. This eliminates volatile organic compound emissions during high-temperature heat sealing while ensuring 100% compliance with EU Directive 2011/65/EU (RoHS) and REACH regulations.
Information Gain Insight: Standard packaging cover tapes often suffer from "peel-force jitter"—fluctuations in adhesion strength caused by ambient humidity and thermal aging. Jiangsu Yongjia’s proprietary surface cross-linking treatment creates an environmental buffer layer, maintaining structural peel integrity across extreme temperature operational windows (-20°C to +180°C).
Tailored high-performance tapes engineered for rigorous demands across semiconductor packaging, automotive electronics, and high-frequency power transformers.
During carrier tape sealing (embossed polycarbonate or paper carrier tapes), maintaining consistent heat-seal adhesion preventing component migration or pocket exposure is paramount. Yongjia’s Standard and Enhanced High-Temperature Series Heat Seal Cover Tapes deliver ultra-clean seal lines without adhesive stringing or static-induced component flipping.
Our Flame-Retardant Acetate Cloth Tape Series (with and without release liners) provides exceptional dielectric breakdown resistance (>3.0 kV) and UL510 flame retardancy. Used extensively in motor winding, transformer inter-layer phase insulation, and harness bundling where high mechanical flexibility and varnish absorption are required.
Leveraging advanced automation, high-speed multi-layer coating lines, and integrated ERP-MES production tracking to guarantee operational continuity and cost efficiency for global electronics OEMs.
Our Nantong facility houses fully enclosed high-precision coating lines equipped with HEPA filtration, eliminating airborne micro-particles down to 0.5 microns to prevent surface pinholes or static hotspots.
High-speed automated slitting machinery maintains slit-width tolerances within ±0.02 mm, preventing tape jam errors in automated carrier packaging machines operating under intense high-throughput settings.
With over 16,000 square meters of production footprint and 18 years of technical evolution, Yongjia supports scalable contract manufacturing, OEM batch customization, and rapid global dispatch.
Rigorous international certifications ensuring compliance with hazardous substance regulations, electrical safety codes, and international export logistics standards.
Operating under certified ISO9001:2015 Quality Management Systems and ISO14001:2015 Environmental Systems, Jiangsu Yongjia maintains full batch traceability for every master roll produced. All raw backing substrates, release liners, and chemical additives are vetted through rigorous XRF spectrometry and GC-MS chromatography testing to guarantee compliance with UL510, RoHS 2.0, REACH SVHC, and Halogen-Free directives required by top-tier automotive tier-1 suppliers and consumer electronics giants.
Frameworks engineered to mitigate supply chain risks, streamline total cost of ownership (TCO), and provide custom product adaptations for enterprise buyers.
Global procurement engineers require zero dynamic peel variation during high-speed unwinding. Our products undergo accelerated aging tests (60°C @ 90% RH for 168 hours) to verify that peel strength shift does not exceed ±10%, safeguarding long-term warehouse storage stability (over 12 months shelf-life guarantee).
To maximize SMT feeder uptime, Yongjia offers custom slit widths ranging from 5.3mm up to 104mm with custom pancake roll lengths or continuous traverse spooling (up to 3,000 meters per spool), minimizing line changeovers for contract manufacturers.
Every batch shipment includes detailed Certificates of Analysis (COA), initial sample inspection reports (ISIR), IMDS data entry support for automotive clients, and real-time peel graph tracking metrics.
Our dedicated R&D laboratory provides rapid prototype sampling within 48 hours for custom backing thickness, special adhesive color formulation, or specialized static-dissipative release liner pairing.

Answers to common engineering and procurement questions regarding cover tape sealing dynamics, anti-static metrics, and wholesale customization parameters.
Heat-Seal Cover Tape utilizes a thermoplastic adhesive coating that requires controlled temperature (typically 130°C to 200°C) and pressure from a sealing shoe to bond with the carrier tape rails. It offers extremely consistent peel force and higher thermal stability. Self-Adhesive Cover Tape relies on a pressure-sensitive adhesive (PSA) layer that bonds instantly upon contact without heat, making it suitable for temperature-sensitive electronic components or simpler packaging machinery.
We employ proprietary polymer cross-linking chemistry in our adhesive formulations along with automated tension-controlled slitting. All master rolls undergo climate chamber aging tests (60°C / 90% RH) to verify that peel strength stays strictly within the standard target range of 0.20 N to 0.80 N under EIA-481 guidelines, eliminating component popping or cover tape tearing during high-speed SMT feeder operations.
Yes. Jiangsu Yongjia’s Flame-Retardant Acetate Cloth Series complies with UL510 flame retardancy standards. They feature excellent dielectric breakdown voltage capabilities (>3 kV), high flexibility, and high resistance to varnish impregnation, making them ideal for transformer coil insulation, motor wrapping, and wiring harness protection.
Our anti-static cover tapes feature dissipative surface coatings providing surface resistivity between 106 and 109 Ω/sq on both the top and sealing sides. This prevents static charge generation during rapid tape peeling, protecting sensitive semiconductor chips and SMD micro-components from ESD damage.
Absolutely. As an OEM/ODM direct factory manufacturer, we offer slit widths from 5.3mm (compatible with 8mm carrier tapes) up to customized widths above 100mm. Standard roll lengths are 300m or 480m, with continuous traverse spooling options up to 3,000m available upon request.
All products manufactured by Jiangsu Yongjia fully comply with EU RoHS Directive 2011/65/EU and REACH (EC 1907/2006) SVHC candidate lists. Test reports from accredited third-party laboratories (SGS/CTI) are provided with complete technical dossiers.
