| 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
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 light blue, single-sided ESD version with a surface resistivity of 106–1010 Ω. The YJRG-59H-1LS is a dark blue, double-sided ESD version with a surface resistivity of 106–1011 Ω, offering the most comprehensive anti-static protection for sensitive components.
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, ensuring reliable sealing adhesion and consistent peel performance throughout the packaging process.
Q
Can the YJRG-59H series be used with high-speed packaging machines?
Yes. The series supports both standard sealing temperatures of 150–180°C and high-speed machine sealing temperatures of 190–250°C. This dual temperature range compatibility makes it suitable for a wide variety of production line speeds and efficiency requirements.
Q
What does the peel force range of 30–90g mean for my application?
A peel force of 30–90g means the cover tape provides a secure seal that reliably holds components in place during transport and handling, while still being easy enough to peel for rework or automated pick-and-place operations without damaging the components or carrier tape.
Q
Why is the 0.055mm thickness significant for this cover tape?
The 0.055mm thickness (±0.006mm tolerance) represents a carefully engineered balance point — thin enough for smooth feeding and handling on automated equipment, yet substantial enough to deliver a tensile strength of ≥2.5kg and elongation of ≥30%, ensuring the tape does not break or deform under normal packaging stresses.
Q
How does the double-sided ESD model protect electronic components?
The YJRG-59H-1LS features anti-static treatment on both surfaces, providing ESD protection from both the top and bottom of the packaged component. With a surface resistivity of 106–1011 Ω, it safely dissipates electrostatic charges that could otherwise damage sensitive ICs, semiconductors, or other ESD-sensitive devices, helping to improve overall product yield.
