    Product Overview

    Series 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.

    Thickness The product features a standard thickness of 0.055mm, a design that achieves an optimal balance between mechanical strength and handling convenience.

    Mechanical 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 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.

    Peel Force The precisely controlled peel force range of 30–90g guarantees sealing reliability while facilitating potential rework operations.

    ESD Protection 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?
    A YJRG-59H is the standard transparent version. YJRG-59H-1L is a light blue single-sided ESD (anti-static) model with a surface resistivity of 10⁶–10¹⁰ Ω. YJRG-59H-1LS is a dark blue double-sided ESD model with a surface resistivity of 10⁶–10¹¹ Ω, offering more comprehensive electrostatic protection on both surfaces.
    Q What carrier tapes are compatible with the YJRG-59H series?
    A The YJRG-59H series is specifically designed for use with PS (polystyrene) carrier tapes, ensuring reliable sealing adhesion and consistent peel force performance throughout the packaging process.
    Q What sealing temperatures are recommended for the YJRG-59H series?
    A For standard sealing machines, the recommended temperature range is 150–180°C. For high-speed packaging machines, the sealing temperature can be set between 190–250°C. This wide temperature adaptability makes the series suitable for various production line configurations.
    Q What does the peel force range of 30–90g mean for end users?
    A A peel force of 30–90g means the cover tape provides a secure seal to prevent components from falling out during transport and handling, while still being easy enough to peel open for rework or inspection without damaging the components or the carrier tape.
    Q Why is the double-sided ESD model recommended for sensitive electronic components?
    A The double-sided anti-static model (YJRG-59H-1LS) dissipates static electricity on both surfaces of the cover tape, providing comprehensive ESD protection. This is especially important for sensitive ICs, MOSFETs, and other electrostatic-sensitive devices (ESDs) that could be damaged by even small static charges during packaging and shipping.
    Q How does the 0.055mm thickness affect the performance of this cover tape?
    A The 0.055mm thickness (±0.006mm tolerance) is carefully engineered to balance mechanical strength and flexibility. It is thick enough to maintain a tensile strength of ≥2.5kg and elongation of ≥30%, ensuring the tape does not break under tension, while being thin enough to feed smoothly through automated high-speed packaging equipment without jamming.
