The product delivers reliable mechanical performance, featuring a tensile strength ≥2.5kg and elongation ≥30%. This parameter combination ensures stable protective performance during both packaging and use.
Regarding thermal properties, this series offers a conventional sealing temperature range of 160-190°C, which is slightly higher than other series, while also accommodating high-speed sealing processes at 190-250°C. This characteristic enables it to meet special process requirements.
The peel force range of 30-90g is rationally designed to ensure secure sealing while maintaining rework convenience. Specifically designed for use with PS carrier tapes, the double-sided anti-static model in this series provides comprehensive protection for highly sensitive electronic components, effectively preventing electrostatic damage and improving product reliability.
❓ Frequently Asked Questions
Q What are the three models in the YJRG-51A series and how do they differ?
The YJRG-51A series includes three models: YJRG-51A (standard transparent), YJRG-51-1L (single-sided ESD, light blue, surface resistivity 10^6–10^10 Ω), and YJRG-51-1LS (double-sided ESD, dark blue, surface resistivity 10^6–10^11 Ω). The main difference lies in their anti-static protection levels and applicable use cases.
Q Why is the 0.06mm thickness considered an advantage for this series?
At 0.06mm, the YJRG-51A series is slightly thicker than comparable cover tape products. This added thickness provides enhanced mechanical protection, making it particularly suitable for applications where components require more robust physical shielding during transport and storage.
Q What sealing temperature range is recommended for the YJRG-51A series?
For conventional sealing equipment, the recommended temperature range is 160–190°C. For high-speed sealing machines, the range extends to 190–250°C. This flexibility allows the series to accommodate a variety of production process requirements.
Q What carrier tape type is compatible with the YJRG-51A series?
The YJRG-51A series is specifically designed for use with PS (polystyrene) carrier tapes. It is important to verify carrier tape compatibility before use to ensure proper sealing performance and component protection.
Q What does the peel force range of 30–90g mean in practical use?
A peel force of 30–90g is carefully balanced to provide secure sealing that prevents accidental opening during handling, while still allowing easy and clean peeling during component pick-and-place operations. This balance is critical for maintaining both product safety and production efficiency.
Q When should I choose the double-sided ESD model YJRG-51-1LS over the single-sided model?
The double-sided ESD model YJRG-51-1LS is recommended for highly sensitive electronic components that require comprehensive electrostatic protection on both surfaces. Its surface resistivity of 10^6–10^11 Ω provides a broader protection range, making it ideal for advanced semiconductor devices and other ESD-sensitive parts.
