    📝 Product Overview
    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
    🔹 What is the difference between YJRG-59H, YJRG-59H-1L, and YJRG-59H-1LS?
    YJRG-59H is the standard transparent base model. YJRG-59H-1L features single-sided ESD protection (light blue, surface resistivity 106–1010 Ω), while YJRG-59H-1LS offers double-sided ESD protection (dark blue, surface resistivity 106–1011 Ω) for more sensitive components requiring comprehensive anti-static coverage.
    🔹 What carrier tapes are compatible with the YJRG-59H series?
    The YJRG-59H series is specifically designed for use with PS (Polystyrene) carrier tapes. Please ensure your carrier tape material is PS to achieve optimal sealing performance and reliable peel force.
    🔹 What sealing temperatures are recommended for this cover tape?
    For conventional sealing machines, the recommended temperature range is 150–180°C. For high-speed packaging machines, the recommended sealing temperature range is 190–250°C, making the series suitable for a wide variety of production line configurations.
    🔹 What does the peel force range of 30–90g mean for my application?
    The peel force range of 30–90g is carefully controlled to ensure the cover tape seals securely enough to protect components during transport and handling, while still allowing for easy and clean removal during rework or automated pick-and-place processes without damaging the components.
    🔹 Is the YJRG-59H series suitable for packaging electrostatic-sensitive components?
    Yes. The YJRG-59H-1L (single-sided ESD) and YJRG-59H-1LS (double-sided ESD) models are specifically designed to protect electrostatic-sensitive electronic components. The double-sided model provides the most comprehensive protection, effectively preventing electrostatic discharge damage and improving overall product yield.
    🔹 What are the key mechanical properties of the YJRG-59H series cover tape?
    The YJRG-59H series features a standard thickness of 0.055mm (±0.006mm tolerance), a tensile strength of ≥2.5kg, and an elongation of ≥30%. These mechanical properties ensure the tape maintains structural integrity and consistent performance throughout high-speed automated packaging processes.
