      Compatible TapeDesigned specifically for PS carrier tapes
    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
    What are the three models in the YJRG-59H series and how do they differ?
    The series includes three models: YJRG-59H (standard transparent), YJRG-59H-1L (single-sided ESD, light blue, surface resistivity 10⁶–10¹⁰ Ω), and YJRG-59H-1LS (double-sided ESD, dark blue, surface resistivity 10⁶–10¹¹ Ω). The main difference lies in their anti-static capabilities, with the double-sided model offering the most comprehensive ESD protection.
    What sealing temperature range is recommended for the YJRG-59H series?
    For standard sealing equipment, the recommended temperature range is 150–180°C. For high-speed machines, the recommended range is 190–250°C, making the series adaptable to a wide variety of production line configurations.
    Which carrier tape type is compatible with the YJRG-59H cover tape series?
    The YJRG-59H series is designed specifically for use with PS (Polystyrene) carrier tapes, ensuring reliable adhesion and consistent peel performance throughout the packaging process.
    What is the peel force of the YJRG-59H series, and why does it matter?
    The peel force is precisely controlled within a range of 30–90g. This range is important because it ensures a secure seal to protect components during transport and storage, while still allowing for easy and clean peeling during component placement or rework operations.
    How does the double-sided anti-static model protect sensitive electronic components?
    The YJRG-59H-1LS features anti-static properties on both surfaces with a surface resistivity of 10⁶–10¹¹ Ω. This dual-sided protection dissipates electrostatic charges effectively, preventing ESD (Electrostatic Discharge) damage to sensitive components such as ICs and semiconductors, thereby improving overall product yield.
    Is the YJRG-59H series suitable for high-speed automated packaging lines?
    Yes. With a tensile strength of ≥2.5kg, elongation of ≥30%, and a high-speed sealing temperature range of 190–250°C, the YJRG-59H series is well-suited for high-speed automated packaging equipment, ensuring stable performance and consistent sealing quality at elevated production rates.
