The YJRG-51A series cover tape consists of the base model YJRG-51A, the single-sided anti-static model YJRG-51-1L, and the double-sided anti-static model YJRG-51-1LS. With a thickness design of 0.06mm, this series is slightly thicker than other series, giving it unique advantages in applications requiring enhanced mechanical protection.
💪
The product delivers reliable mechanical performance, featuring a tensile strength of ≥2.5kg and elongation of ≥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 differences between YJRG-51A, YJRG-51-1L, and YJRG-51-1LS?
YJRG-51A is the standard transparent version with no anti-static function. YJRG-51-1L is a light blue single-sided ESD version with a surface resistivity of 106–1010 Ω, offering anti-static protection on one side. YJRG-51-1LS is a dark blue double-sided ESD version with a surface resistivity of 106–1011 Ω, providing comprehensive anti-static protection on both surfaces for the most sensitive electronic components.
Q
What carrier tapes is the YJRG-51A series compatible with?
The YJRG-51A series cover tape is specifically designed to be compatible with PS (Polystyrene) carrier tapes. It is important to confirm carrier tape material compatibility before use to ensure proper sealing adhesion and peel performance.
Q
What sealing temperature should I use for the YJRG-51A series?
For standard sealing equipment, the recommended sealing temperature is 160–190°C. For high-speed sealing machines, the recommended temperature range is 190–250°C. Always refer to your specific machine settings and run test seals to confirm optimal parameters before full production.
Q
What does the peel force range of 30–90g mean for practical use?
A peel force of 30–90g means the tape provides a secure seal to prevent components from falling out during transport and handling, while still being easy to peel open during the SMT pick-and-place process. This range is carefully balanced to support both automated reel feeding and manual rework operations without damaging components.
Q
Why is the YJRG-51A series slightly thicker than other cover tape series?
At 0.06mm thickness, the YJRG-51A series is designed for applications that require enhanced mechanical protection. The additional thickness provides greater resistance to puncture, tearing, and deformation during transportation and automated handling, making it suitable for components that need a higher level of physical protection.
Q
When should I choose the double-sided ESD model YJRG-51-1LS over the single-sided version?
The double-sided ESD model YJRG-51-1LS is recommended when packaging highly sensitive electronic components such as advanced ICs, MOSFETs, or precision sensors that are susceptible to electrostatic discharge from any direction. The dual-layer anti-static protection (surface resistivity 106–1011 Ω) ensures that both the component-facing side and the outer surface dissipate static charges, providing a higher level of ESD safety compared to the single-sided version.
