Mechanical Performance
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.
🌡️
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.
⚡
ESD Protection & Peel Force
The peel force range of 30–90g ensures secure sealing while maintaining rework convenience. Specifically designed for PS carrier tapes, the double-sided anti-static model provides comprehensive protection for highly sensitive electronic components, effectively preventing electrostatic damage and improving product reliability.
❓ Frequently Asked Questions
Q
What is the difference between YJRG-51A, YJRG-51-1L, and YJRG-51-1LS?
YJRG-51A is the standard transparent cover tape. YJRG-51-1L is the single-sided anti-static version (light blue) with a surface resistivity of 10⁶–10¹⁰ Ω, while YJRG-51-1LS is the double-sided anti-static version (dark blue) with a surface resistivity of 10⁶–10¹¹ Ω. The ESD variants are designed for environments where electrostatic discharge protection is critical.
Q
Why is the YJRG-51A series slightly thicker than other cover tape series?
The YJRG-51A series has a thickness of 0.06mm, which is slightly thicker than comparable series. This design choice provides enhanced mechanical protection, making it ideal for applications where components require additional physical shielding during transport and handling.
Q
What sealing temperature is recommended for the YJRG-51A series?
For standard sealing equipment, the recommended temperature range is 160–190°C. For high-speed sealing machines, the recommended range is 190–250°C. These ranges are slightly higher than other series, so operators should verify their equipment settings before production.
Q
What carrier tape is compatible with the YJRG-51A series?
The YJRG-51A series is specifically designed to be compatible with PS (Polystyrene) carrier tapes. It is important to confirm carrier tape compatibility before use to ensure proper sealing and reliable component delivery during automated assembly.
Q
What does the peel force range of 30–90g mean in practical use?
The peel force range of 30–90g is engineered to balance two key requirements: secure sealing to prevent component loss during shipping and handling, and easy peelability to allow smooth rework or component retrieval without damaging sensitive parts.
Q
When should I choose the double-sided anti-static model YJRG-51-1LS over the single-sided version?
The double-sided anti-static model YJRG-51-1LS is recommended when packaging highly sensitive electronic components that require ESD protection on both surfaces. It offers a broader surface resistivity range (10⁶–10¹¹ Ω) and provides more comprehensive electrostatic shielding compared to the single-sided YJRG-51-1L, making it suitable for the most demanding anti-static applications.
