Keep your used SMT pick and place machines running longer and more reliably. Discover 7 proven maintenance tips to extend lifespan, reduce downtime, and boost productivity.
In the competitive world of electronics manufacturing, optimizing your SMT (Surface Mount Technology) equipment performance is crucial. For companies using used SMT pick and place machines, proper care and maintenance can significantly extend the life of the equipment, enhance placement accuracy, and reduce unexpected downtime.

Here are 7 expert-proven tips to help you keep your machines in peak condition.
đź”§ Tip 1: Conduct Daily Visual Inspections
Start each shift with a quick visual inspection. Look for loose belts, misaligned feeders, or nozzle blockages. Early detection of small issues can prevent major breakdowns. Check:
- X/Y axis movement
- Feeder slot integrity
- Vacuum pipes for leakage

đź§˝ Tip 2: Clean Nozzles and Cameras Daily
Dirt and dust can affect vacuum suction and image recognition. Wipe the nozzle tips, camera lenses, and pickup heads after each production shift using IPA or dedicated SMT cleaning swabs.

đź› Tip 3: Lubricate Moving Parts Weekly
Proper lubrication reduces wear on key moving parts such as:
- Guide rails
- Lead screws
- Bearings
Use manufacturer-recommended grease and avoid over-lubrication, which can attract dust.
🔍 Tip 4: Check Vacuum Systems Monthly
The vacuum system powers the pickup and placement process. Examine:
- Vacuum pressure (ideally above 0.6 MPa)
- Dust filters for clogs
- Tubing connections and air valves
We recommend replacing vacuum filters every 3 months for optimal suction.
⚡ Tip 5: Inspect Electrical Connections Quarterly
Loose connectors or aging relay components can cause intermittent faults. Every 3 months:
- Tighten terminal screws
- Check PCB boards for corrosion
- Test sensors and encoders

📊 Tip 6: Use Predictive Maintenance Tools
If your line uses newer pick and place systems, implement data-driven maintenance by:
- Monitoring nozzle wear patterns
- Setting cycle count thresholds for part replacement
- Using built-in diagnostics and maintenance alerts
This reduces unplanned downtime and saves on major repairs.
👨‍🔧 Tip 7: Train Operators & Work with Trusted Suppliers
Operator error is a common cause of machine failure. Provide:
- Regular training on startup/shutdown routines
- Documentation for troubleshooting
- A reliable supplier for parts & service
