    ❓ Frequently Asked Questions
    Q What is the peel adhesion force range of YJLG-80/81, and what does it mean for my application?
    The peel adhesion force is controlled between 30–70 grams. This low-tack range ensures the tape bonds effectively during the encapsulation process but can be removed cleanly and easily without leaving any adhesive residue — making it ideal for applications that require high surface cleanliness on precision components.
    Q What anti-static options are available for YJLG-80/81?
    YJLG-80/81 offers three anti-static configurations: single-sided brown (10⁵–10⁸Ω), single-sided light blue (10⁶–10¹⁰Ω), and double-sided anti-static (10⁶–10¹¹Ω). Users can select the appropriate grade based on the electrostatic sensitivity level of their components.
    Q What standard width specifications are available, and can custom sizes be ordered?
    Standard widths range from 5.4mm to 97.5mm. In addition, custom sizes are fully supported to accommodate specific production line requirements or non-standard component dimensions.
    Q Is YJLG-80/81 suitable for high-speed automated mounting processes?
    Yes. With a tensile strength of ≥2.5kg and elongation of ≥30%, the tape is designed to withstand the mechanical stress of high-speed mounting and transportation without breaking or deforming, ensuring consistent performance in automated production environments.
    Q What types of components or industries is YJLG-80/81 most commonly used in?
    YJLG-80/81 is widely used in light encapsulation applications including LED components and flexible circuit boards (FPCs), where a combination of gentle adhesion, easy peel-off, and reliable electrostatic protection is essential to protect sensitive electronic parts.
    Q How precise is the thickness control of YJLG-80/81?
    The tape maintains a uniform thickness of 0.06mm with a tight tolerance of ±0.005mm. This level of precision ensures consistent performance across the entire roll, which is critical for maintaining dimensional accuracy in precision encapsulation and assembly processes.
