Product Description

Upper Cover Tape

This product is manufactured using special composite materials and precision coating technology, enabling it to maintain stable adhesive performance within a broad temperature range of -10°C to 60°C, ensuring reliable packaging effects under various environmental conditions. The product features precisely controlled peel strength, preventing adhesive residue during automatic peeling and effectively avoiding contamination of precision components.

Anti-Static Design

Maintains surface resistivity within 10^6 to 10^9 Ω, eliminating component displacement risks.

📏
Multi-layer Structure

Thickness controlled within 0.05-0.08 mm for mechanical strength and flexibility.

🚀
High-Speed Production

Accommodates production speeds of up to 300 cycles per minute on automatic equipment.

The product employs a multi-layer composite structure, with a surface layer that offers excellent abrasion and tear resistance, a middle functional layer that provides stable adhesive strength, and a bottom protective film that ensures cleanliness during transportation and storage. In practical applications, the top cover tape is perfectly compatible with various types of carrier tapes, including plastic ones such as PS, PET, and PC, as well as specialized paper-based carrier tapes.

Lower Cover Tape

This product is manufactured using high-strength composite materials, offering excellent dimensional stability and mechanical strength to ensure consistent shape and performance in high-speed automated production processes. The surface is specially treated to provide an appropriate friction coefficient and outstanding anti-static properties.

🎯
