1. Preparation Before Calibration

Ensure the workspace is clean, level, and ESD-safe. Gather necessary tools such as leveling meters, torque wrenches, and calibration jigs. Verify that the tray loader is properly installed according to the Equipment Selection Guide.

2. Mechanical Calibration Steps

Start with the physical alignment of the tray loader. Proper mechanical calibration prevents misfeeds and component misalignment.

🔧 Step-by-Step Mechanical Calibration

1. Check that the loader frame is level and secured.
2. Adjust tray guides to match the standard tray width.
3. Verify the tray magazine height aligns with pick-and-place machines.
4. Tighten all mechanical fasteners and lock positions.

3. Electrical & Sensor Calibration

Connect all sensors, switches, and power supplies. Ensure the sensors are aligned and functioning correctly. Refer to SMT Basics for sensor operation principles.

4. Software Configuration

Configure the tray loader controller for your tray types and line integration:

• Define tray dimensions and component coordinates.
• Link to MES or ERP system if applicable.
• Set safety limits and interlocks.

5. Testing & Verification

Before full production, run calibration tests with empty trays:

🧭 Testing Checklist

• Verify tray pick and drop positions.
• Confirm sensor signals are consistent.
• Run 10 dry cycles to check repeatability.
• Adjust any minor misalignments.

6. Common Calibration Issues

• Tray misalignment: Re-level the frame or adjust tray guides.
• Sensor errors: Clean sensors and verify wiring.
• Software misconfigurations: Check coordinate mapping.
