During Operation Monitoring
While the machine is running, operators should remain attentive to catch issues early :
Visual Checks:
- Cover tape peeling looks correct; tape moving consistently
- No tape breaks or tears
- Placement positions remain correct (not drifting)
- No unexpected head motion (jerking, hesitation)
Auditory Checks:
- No unusual sounds from placement head
- No repeated "miss" sounds indicating missing components
- No abnormal sounds from feeder advancement
- No clicking, grinding, scraping, or repeated knocking
Action Protocol:
- Stop the machine immediately if any abnormal sounds or movements are detected
- Correct simple, safe issues (minor tape interruption, visible debris)
- For suspected mechanical or electrical issues, contact technical support
Weekly Maintenance Tasks
| Task |
Procedure |
| Check Lubrication Levels |
Inspect motors and axes; low lubrication increases friction and causes premature wear -2 |
| Inspect Belts and Chains |
Check for stretching, cracks, or looseness; replace if damaged -2 |
| Clean Camera System |
Use clean, lint-free cloth to wipe lens gently -2 |
| Inspect X/Y Axes |
Ensure no abnormal noise while placement head moving -10 |
| Check X/Y Motors |
Verify motors not overheating |
Monthly Maintenance Tasks
| Task |
Procedure |
| X-Axis Lead Screw & Linear Guide |
Clean dust from guide and screw; apply grease to lubrication ports; move head horizontally 3-4 times to distribute |
| Y-Axis Lead Screw & Linear Guide |
Clean dust; apply grease to lubrication ports; move head to ensure even coverage |
| Track Width Adjustment Lead Screw |
Adjust to maximum width; clean dust; apply grease with brush |
| Nozzle Inspection |
Check for bend; verify nozzle surface is horizontal |
| Air Hoses |
Check connections for wear or air leaks |
| Z-Axis Motor |
Verify placement head goes up/down smoothly |
| Vacuum Pressure |
Check all nozzles' vacuum pressure; clean if abnormal |
| Positive Pressure |
Verify normal positive pressure |
| Optical Axis |
Clean and lubricate if covered with dust |
| Operation Buttons |
Check each button functions properly |
| Electrical Connections |
Inspect for loose or corroded connections; check cables for overheating signs |
| Air Filters |
Replace or clean as needed |
| Filter Replacement |
Replace filters (typically once per month) |
| Step Motors/Synchronous Belts |
Check for dirt; ensure Z-axis motor can up/down and rotate smoothly |
| SMT Feeders |
Inspect for looseness or abnormalities |
| IC Tray Holder |
Verify secure |
| Oil-Water Separator |
Drain accumulated water |
| Nozzle Magazine |
Remove excess material and debris |
Quarterly and Annual Maintenance
| Interval |
Tasks |
| Quarterly |
Professional technician inspection using specialized diagnostic tools; check control board and servo motors |
| Annually |
Full-scale maintenance overhaul; disassemble parts for thorough cleaning and inspection; check for hidden damage; replace worn parts; final calibration |
Part 2: Preventive Care Best Practices
Environmental Control
The working environment significantly impacts maintenance frequency :
| Factor |
Recommended Condition |
| Temperature |
20°C–26°C |
| Humidity |
40–70% RH |
| Cleanliness |
ISO 14644-1 Class 7 cleanroom standards recommended for optimal performance |
| Airflow |
No strong airflow directed at machine |
Note: In dusty environments, increase cleaning frequency. Multiple daily cleanings may be necessary for feeders and nozzles in extreme conditions.
Operator Management
Proper operator training and protocols prevent human error :
| Requirement |
Description |
| Certified Training |
Only personnel trained by the company may operate equipment |
| Single Operation |
Never allow two operators to operate the same machine simultaneously |
| First Article Inspection |
Check the first finished PCB of each file; find solutions for any problems |
| Component Verification |
When changing reels, verify new tape matches correct component |
| Program Verification |
After programming, double-check component numbers, placement positions, and angles |
| Regular Monitoring |
Check placement position and component loss during regular work |
Documentation and Maintenance Logs
Keep detailed records of all maintenance activities :
- Date of last maintenance
- Type of service performed
- Parts replaced
- Observations and findings
- Calibration results
This log helps identify patterns, schedule preventive maintenance, and supports warranty claims or audits.
Software and Firmware Updates
Keep your machine's software current :
- Check for manufacturer updates regularly
- Back up data before installing updates
- Updates fix bugs and may introduce new features
- Ensures compatibility with other factory equipment
Part 3: When to Stop and Call for Support
Stop operation immediately if you observe any of the following :
| Warning Sign |
Description |
| Abnormal Movement |
Jerky motion, binding, hesitation, drifting |
| Abnormal Sounds |
Grinding, repeated knocking, air leaks |
| Nozzle Issues |
Bent, crooked, or nozzles that don't return smoothly |
| Feeder Problems |
Tape not indexing, snagging, inconsistent feed |
| Camera Issues |
Spots, blur, poor contrast |
When contacting technical support, provide :
- A short description of what you observed
- When it happens (startup, homing, during placement, during feeder indexing)
- Photos or video of the issue if possible
