What Is Pressure Sensitive Cover Tape?
Pressure Sensitive Cover Tape from Sierra Electronics is a specialized adhesive film designed to seal and protect surface mount device packaging in tape-and-reel workflows without requiring heat activation. Unlike traditional heat-activated cover tapes, this product uses a pressure-sensitive adhesive that forms a strong bond simply through applied pressure. This makes it particularly effective for fast-paced SMT assembly environments where efficiency and consistency are critical.
Why Choose Pressure Sensitive Cover Tape for SMT Lines
In modern electronics manufacturing, maintaining component integrity from storage through automated pick-and-place operations is essential. Sierra Electronics Pressure Sensitive Cover Tape delivers consistent sealing performance that supports high-reliability production by:
- Eliminating the need for heat-seal equipment and temperature control
- Reducing setup time and operational complexity
- Maintaining secure adhesion under tension during reel handling and feeding
- Providing high transparency for easy visual inspection of components
These advantages help manufacturers minimi
