Engineered to deliver high thermal resistance, consistent mechanical properties, and electrostatic discharge protection. Adapted for cleanroom integrations and automatic SMT pick-and-place packaging systems.
In the contemporary global semiconductor supply chain, the packaging of surface mount devices (SMD) and passive electronic components acts as the lifeline for automated printed circuit board (PCB) assembly. As microchips, chipsets, capacitors, and resistors continue their aggressive trajectory toward miniaturization—such as the widespread adoption of 0201 and 01005 packages—the mechanical and electrical properties of carrier tapes and cover tapes have become critical variables.
Historically, component packaging was viewed purely as a logistics mechanism to transport parts from point A to point B. Today, it is recognized as a precision system. The cover tape must seal flawlessly to the carrier tape pockets without leaving residue, maintain a highly stable peel force over prolonged storage, and discharge any triboelectric charges generated during high-speed unwinding. Globally, manufacturers must balance cost efficiency with the strict technical frameworks outlined in international standards such as EIA-481 (Electronic Industries Alliance standard for embossing packaging of components).
Jiangsu Yongjia Electronic Materials Co., Ltd. has established itself at the forefront of this industrial segment. The integration of high-precision multi-layer co-extrusion technology enables the production of cover tapes with superior optical transparency, allowing optical inspection systems (AOI) to verify component presence and orientation through the sealed tape prior to entering the automated pick-and-place lines.
Samoa, nestled in the heart of the Pacific, is witnessing a strategic shift towards localized light industrial manufacturing, clean-energy grid components assembly, and maritime logistics. The Samoan government’s focus on sustainable infrastructure development, combined with the expansion of high-speed fiber-optic submarine cables (such as the Tui-Samoa Cable), has catalyzed interest in building localized assembly hubs for telecommunications equipment, solar invertor components, and smart electrical metering devices.
Jiangsu Yongjia’s customized high-temperature series heat seal cover tapes and anti-static self-adhesive cover tapes are tailored to counteract these microclimatic factors. By utilizing hydrophobic adhesive layers and polymer formulations that resist moisture absorption, we ensure that electronic component manufacturers serving Samoa encounter zero tape-related assembly failures or component dropouts during automated feeding.
Decades of engineering excellence backed by structured quality control systems and certified production environments.
To fully appreciate the performance required of tapes used to package electronic components, one must examine the interfacial chemistry of cover tapes. The core challenge lies in maintaining a stable peel force window (typically between 10 grams and 130 grams for an 8mm tape width) under varying temperatures and speeds.
Heat Seal Cover Tape (HSA): These tapes employ a thermoplastic adhesive layer that activates under precise application of thermal energy (usually 140°C to 210°C) and pressure from a sealing shoe. The adhesive is engineered to form a strong cross-linked bond with standard carrier tape materials, such as Polystyrene (PS), Polycarbonate (PC), or Polyethylene Terephthalate (PET). The formulation must prevent "aging creep," which causes the peel force to rise to unacceptable levels over time, preventing the automated nozzle from removing the tape during SMT processes.
Self-Adhesive Cover Tape (PSA): Pressure-sensitive alternatives rely on acrylic or silicone-based macromolecular polymers that form an immediate mechanical bond upon application of pressure. PSA tapes are highly favored for heat-sensitive components, such as optical sensors, advanced memory modules, and high-frequency oscillators, where exposure to sealing shoe heat could compromise the internal architecture of the chip.
Flame-Retardant and High-Tensile Insulators: For inter-module isolation and electrical insulation within high-power devices, acetate cloth tapes and glass fiber tapes serve as critical packaging and shielding agents. Acetate cloth offers excellent flexibility and high absorption of varnish, making it ideal for wire harness wrapping, while glass fiber tapes contribute unparalleled tensile strength to resist mechanical shearing under high-voltage environments.
Understanding the performance metrics is key to selecting the correct tape. Below is a macro overview of typical technical specifications across our functional tape portfolio:
A leading domestic integrated provider of functional tapes for the global electronics, automotive, and semiconductor packaging industries.
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 tape products with considerable influence in the industry. Located in the vibrant industrial environment of Nantong, the company covers an area of 16,000 square meters, with a building area of 9,000 square meters. Its scientifically planned production workshops, R&D laboratories, and office spaces are rationally designed, laying a solid foundation for high-quality development.
Our manufacturing facility operates multiple high-speed coating lines, slitting machines, and cleanroom packaging facilities to ensure all semiconductor cover tape products meet the stringent particle contamination standards required by Class 1000 cleanrooms. We export high-end packaging solutions to major manufacturing centers across Southeast Asia, North America, Europe, and now provide dedicated shipping channels and engineering consultation services to operations based in Samoa.
Our functional tapes solve complex packaging, shielding, and insulating challenges across diverse industrial domains.
High-tensile flame-retardant acetate cloth tapes are deployed for wire harness wrapping, providing superior heat insulation and anti-vibration damping for Samoa's automotive infrastructure.
Temporary fixing and protection of lead frames and micro-stamped terminals during high-speed reel-to-reel plating operations, leaving zero adhesive residue.
ESD-safe cover tapes designed to seal IC chips inside carrier pockets, ensuring complete protection during shipping to global assembly lines from Samoa ports.
Glass fiber and heavy-duty PET tapes for transformer coil wrapping, smart grid box insulation, and long-term protection against salt spray and moisture.
Our ISO9001 and environmental protection credentials guarantee that every batch meets local and international compliance directives.




As environmental sustainability regulations (such as RoHS 3.0 and REACH Annex XVII modifications) become increasingly stringent, Jiangsu Yongjia is actively steering its research towards green, halogen-free, and bio-based polymeric backings. Our R&D roadmap outlines three key strategic areas:
Degradable Cover Tape Films: Developing polylactic acid (PLA) based cover tapes that maintain mechanical rigidity and optical clarity comparable to standard PET, but decay efficiently in organic composting environments, directly helping Samoa achieve its long-term waste reduction and green national directives.
Ultra-Low Triboelectric Charging Adhesives: Traditional tapes can generate static voltages exceeding 100V during ultra-fast peeling (rates of 120-150 pocket removals per minute). Our new adhesive formulations leverage crosslinked block-copolymers that limit peel-voltage to under 10V, protecting sensitive sub-10nm transistor architectures.
Optimized Gauges for Miniaturization: Decreasing the standard thickness of cover tapes from 50μm down to 30μm and 25μm without losing tensile strength. Thin-gauge materials maximize the footage per reel, reducing shipping costs and minimizing machine downtime due to reel changes at assembly facilities.
