    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 0.055 mm, a design that achieves an optimal balance between mechanical strength and handling convenience.

    It demonstrates excellent mechanical properties, with a tensile strength ≥2.5 kg 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 30–90 g 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 is the difference between YJRG-59H, YJRG-59H-1L, and YJRG-59H-1LS?
    The YJRG-59H is the standard transparent model with no anti-static treatment. The YJRG-59H-1L is a single-sided ESD version in light blue, with a surface resistivity of 106–1010 Ω. The YJRG-59H-1LS is a double-sided ESD version in dark blue, offering surface resistivity of 106–1011 Ω for more comprehensive electrostatic protection.
    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 reliable adhesion and consistent peel force during automated component packaging and handling.
    Q What sealing temperature range is recommended for the YJRG-59H series?
    For conventional sealing equipment, the recommended temperature range is 150–180°C. For high-speed packaging machines, the sealing temperature can be increased to 190–250°C, allowing the tape to meet diverse production line efficiency requirements.
    Q Why is the peel force range of 30–90 g important?
    The controlled peel force range of 30–90 g ensures that the cover tape forms a reliable seal to protect components during transport and storage, while still allowing easy and clean removal during rework or automated pick-and-place operations without damaging sensitive parts.
    Q How does the double-sided anti-static model protect electronic components?
    The YJRG-59H-1LS features anti-static treatment on both surfaces, providing surface resistivity of 106–1011 Ω. This dual-sided protection dissipates electrostatic charges from both the tape surface and the component interface, significantly reducing the risk of electrostatic discharge (ESD) damage to sensitive electronic parts and improving overall product yield.
    Q What mechanical properties make the YJRG-59H series suitable for high-speed packaging?
    The YJRG-59H series offers a tensile strength of ≥2.5 kg and an elongation of ≥30%, combined with a precisely controlled thickness of 0.055 mm (±0.006 mm). These properties ensure the tape maintains structural integrity, resists tearing, and performs consistently under the mechanical stresses of high-speed automated packaging equipment.
