Pocket Spacing
Pocket spacing is the center-to-center distance between consecutive component pockets in carrier tape - it defines feeder indexing step and pick timing synchronization.
What Is Pocket spacing?
- Definition: Pocket pitch is standardized by component class and tape format specifications.
- Machine Interface: Feeder advance increments must match spacing exactly for proper pick position.
- Orientation Control: Pocket geometry and spacing together maintain component alignment.
- Error Sensitivity: Incorrect pitch interpretation causes no-pick or mispick events.
Why Pocket spacing Matters
- Placement Yield: Correct indexing is required for consistent nozzle pickup accuracy.
- Throughput: Stable pocket stepping minimizes feeder retries and cycle interruptions.
- Automation Reliability: Pitch mismatch can create repetitive line stoppage patterns.
- Traceability: Pocket indexing consistency supports accurate component count and usage logging.
- Setup Robustness: Pitch awareness is essential during new-part onboarding.
How It Is Used in Practice
- Feeder Verification: Confirm pitch settings during setup checklist execution.
- Pilot Run: Perform short dry-run pickup validation before production release.
- Supplier Control: Audit tape pocket dimensions and spacing compliance for critical parts.
Pocket spacing is a key indexing parameter for reliable feeder operation - pocket spacing accuracy should be validated early because indexing errors can quickly propagate into line-wide defects.
