    The YJRG-59H series cover tape comprises the base model YJRG-59H, the single-sided anti-static model YJRG-59H-1L, and the double-sided anti-static model YJRG-59H-1LS. The product features a standard thickness of 0.055mm, a design that achieves an optimal balance between mechanical strength and handling convenience. It demonstrates excellent mechanical properties, with a tensile strength ≥2.5kg and an elongation ≥30%. This combination of parameters ensures stable performance during high-speed packaging processes. Thermal performance data indicates that this series is suitable for conventional sealing temperatures of 150–180°C, while also meeting the requirements for high-speed sealing at 190–250°C. This temperature adaptability allows it to fulfill various production efficiency needs. The precisely controlled peel force range of 30–90g guarantees sealing reliability while facilitating potential rework operations. Designed specifically for use with PS carrier tapes, the double-sided anti-static model within the series provides comprehensive protection for sensitive electronic components, effectively preventing electrostatic damage and improving product yield.
    ❓ Frequently Asked Questions
    Q What are the differences between YJRG-59H, YJRG-59H-1L, and YJRG-59H-1LS?
    The YJRG-59H is the standard transparent base model. The YJRG-59H-1L is a single-sided anti-static version (light blue) with a surface resistivity of 106–1010 Ω, while the YJRG-59H-1LS is a double-sided anti-static version (dark blue) with a surface resistivity of 106–1011 Ω, offering the highest level of ESD protection among the three.
    Q What carrier tape is the YJRG-59H series compatible with?
    The YJRG-59H series cover tape is specifically designed for use with PS (Polystyrene) carrier tapes, ensuring optimal adhesion, sealing performance, and reliable peel force throughout the packaging process.
    Q What sealing temperature range is recommended for high-speed packaging machines?
    For high-speed packaging machines, the recommended sealing temperature range is 190–250°C. For standard or conventional sealing equipment, the recommended range is 150–180°C. This wide temperature adaptability makes the series suitable for a variety of production environments and efficiency requirements.
    Q What is the peel force of the YJRG-59H series, and why does it matter?
    The peel force of the YJRG-59H series is precisely controlled within 30–90g. This range is carefully engineered to ensure a secure seal that protects components during transport and storage, while still allowing for easy and clean removal during rework or component placement operations without damaging the carrier tape or components.
    Q How does the double-sided anti-static model protect sensitive electronic components?
    The YJRG-59H-1LS double-sided anti-static cover tape provides ESD protection on both surfaces, with a surface resistivity of 106–1011 Ω. This effectively dissipates electrostatic charges that could otherwise damage sensitive electronic components such as ICs, semiconductors, and passive components, thereby improving product yield and reducing ESD-related failures.
    Q What mechanical properties make the YJRG-59H series suitable for high-speed packaging?
    The YJRG-59H series offers a tensile strength of ≥2.5kg and an elongation rate of ≥30%, combined with a precisely controlled thickness of 0.055mm (±0.006mm). These mechanical characteristics ensure the tape remains dimensionally stable, resists tearing, and performs consistently under the tension and speed demands of automated high-speed packaging lines.
