    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 cover tape. The YJRG-59H-1L is a single-sided anti-static (ESD) version in light blue, with a surface resistivity of 106–1010 Ω. The YJRG-59H-1LS is a double-sided anti-static version in dark blue, offering surface resistivity of 106–1011 Ω for enhanced protection on both sides of the tape.
    Q
    What carrier tapes are compatible with the YJRG-59H series?
    The YJRG-59H series cover tapes are specifically designed for use with PS (Polystyrene) carrier tapes. Using the correct carrier tape ensures proper adhesion, reliable sealing, and consistent peel force performance throughout the packaging process.
    Q
    What sealing temperatures are recommended for the YJRG-59H series?
    For standard sealing equipment, the recommended temperature range is 150–180°C. For high-speed packaging machines, the recommended sealing temperature is 190–250°C. This broad temperature adaptability makes the series suitable for a wide range of production environments and efficiency requirements.
    Q
    What does the peel force range of 30–90 g mean for practical use?
    A peel force of 30–90 g means the cover tape provides a secure seal that protects components during transport and handling, while still being easy enough to peel off cleanly during automated pick-and-place operations. This range also supports potential rework without damaging the carrier tape or the electronic components inside.
    Q
    Why is the double-sided anti-static model recommended for sensitive electronic components?
    The double-sided anti-static model YJRG-59H-1LS provides ESD protection on both surfaces of the tape. This comprehensive coverage effectively dissipates electrostatic charges from all directions, significantly reducing the risk of electrostatic damage to sensitive semiconductor devices, ICs, and other ESD-sensitive components, ultimately improving overall product yield.
    Q
    How does the 0.055 mm thickness contribute to the performance of YJRG-59H series tapes?
    The 0.055 mm standard thickness (with a tight tolerance of ±0.006 mm) is carefully engineered to strike an optimal balance between mechanical strength and handling convenience. It ensures the tape is robust enough to maintain a tensile strength of ≥2.5 kg and elongation of ≥30%, while remaining thin and flexible enough for smooth, consistent feeding and sealing on both standard and high-speed packaging machines.
