Common SMT Feeder Jamming Issues: Poor Lubrication Is Often to Blame!

In SMT production lines, the feeder plays a crucial role in delivering components accurately and efficiently to the pick-and-place head. However, many production teams struggle with common feeder issues such as jamming, misfeeds, and inconsistent movement. Did you know that over 60% of these problems are caused by improper or insufficient lubrication?

? Common Feeder Jamming Symptoms

1. Startup Resistance – Feeder struggles to move at machine start

2. Intermittent Jamming – Feeder stops randomly during operation

3. Shaky Feeding – Inconsistent motion causes misalignment or skipping

4. Component Misplacement – Precision drops, affecting placement yield

5. Frequent Error Alerts – System reports “Feeder error” repeatedly

? Root Cause: Inadequate or Incorrect Lubrication

❌ Common Mistakes:

• Ignoring internal gears, springs, and rails during maintenance

• Using general-purpose grease instead of high-speed grease

• Applying low-quality grease that dries or evaporates quickly

• Over-lubricating, leading to dust attraction and clogging

? Conclusion

Feeder jamming may seem like a mechanical issue, but it often starts with neglected lubrication. Choosing the right grease and maintaining a regular cleaning routine can significantly extend feeder life and improve your SMT line’s stability.
