How to Handle a Clogged Pick-and-Place Machine Nozzle

A clogged nozzle causes pickup failures and misplaced components. Learning how to handle a clogged pick‑and‑place machine nozzle will save you from unnecessary downtime. SMTFullLine provides both cleaning solutions and replacement parts.

Signs of a Clogged Nozzle

• Frequent “pickup error” for components that used to work.

• Component drops during movement.

• Reduced vacuum reading (check sensor).

Step‑by‑Step Cleaning Procedure

1. Remove the nozzle from the placement head using tweezers or a wrench.

2. Inspect visually – use a magnifier; you may see paste or dust blocking the tip.

3. Cleaning methods :

   • Wire method – Gently poke with a fine nozzle cleaning wire (0.1‑0.3mm).

   • Alcohol soak – Soak in isopropyl alcohol for 5‑10 minutes, then blow air through.

   • Ultrasonic cleaner – Best for deep cleaning multiple nozzles.

4. Reinstall and test – Run a test pickup cycle.

When Cleaning Isn’t Enough

If the nozzle is physically worn (cracked, enlarged hole, deformed tip), replace it immediately. SMTFullLine stocks nozzles for all common pickup tool sizes (0.5mm to 5.0mm ID). We also sell nozzle cleaning kits with wires, alcohol wipes, and storage cases.

Keep your nozzles perfectly clear.
