What Pre-punched Paper Carrier Tape with Round Center Cavity Actually Is
Pre-punched paper carrier tape with a round center cavity is designed for SMD and SMT assembly applications where precise part positioning and reliable feeding are critical. The tape has pre-formed pockets with a central hole at the bottom, eliminating the need for adhesive bottom cover tape. This reduces material use and production cost. The absence of burrs and the internal middle hole prevent electrostatic adhesion and 'throwing' of light, thin components during feeding. The tape is available in custom round, ellipse, square, rectangular, and shaped pockets, with dimensions tailored to specific device profiles. It is made from paper with a thickness of 0.42mm and is suitable for use with standard reel systems.

- No bottom cover tape required, reducing material and processing cost
- Central hole at the bottom prevents electrostatic adhesion and component 'throwing' during feeding
- No burrs on the middle hole or pocket edges, eliminating dander and mechanical damage
- Custom pocket shapes and sizes available for non-standard components
- Pocket depth (K0) adjustable based on paper tape thickness for secure part retention

Pre-punched Paper Carrier Tape with Round Center Cavity Against the Alternatives
| Standard paper carrier tape with adhesive bottom | This tape eliminates adhesive use, reducing cost and waste, and avoids adhesive residue on components |
|---|---|
| Plastic carrier tape | Paper tape is lower cost and more environmentally friendly, but less durable under high humidity or long storage |
| Tape with no middle hole | The middle hole prevents electrostatic adhesion and component ejection, especially for thin or light parts |
| Standard stock tape with fixed pockets | Custom pockets require one-time die setup but allow fit for non-standard components that stock tape cannot hold |
Using Pre-punched Paper Carrier Tape with Round Center Cavity
- Provide a drawing, component sample, or dimension sheet to define the pocket shape and size
- Confirm pitch (P1) based on your feeder magazine spacing before tooling
- Specify whether the middle hole is needed and its required diameter
- Choose pocket depth (K0) based on component thickness to ensure secure retention
- Use the tape within 6 months of production to avoid moisture absorption and deformation
- Store reels flat in dry, cool conditions away from direct sunlight
- Allow 5-15 days for lead time after sample approval, with MOQ of 5000 meters
