Operation Guide for Selective Wave Soldering Machines
Step-by-Step Instructions
Welcome to the Operation Guide for our Selective Wave Soldering Machines. This section will walk you through the essential steps to ensure efficient, safe, and precise soldering operations. Whether you’re working with an online system like the AFS-250C or an offline system like the FS-250C, our step-by-step instructions are designed to help you achieve consistent results while optimizing machine performance.
Initial Setup:
Position the PCB: Ensure the PCB is properly aligned on the machine's conveyor or manual positioning platform, depending on the model.
Load the Flux: For models with flux spraying, load the correct type and amount of flux to suit your PCB type and production volume.
Preheating:
Adjust Temperature Settings: Set the preheating temperature based on the PCB material and the required soldering process. Models with preheating modules like the FPS-250C ensure uniform heating for optimal results.
Check Heating Stages: Ensure the preheating stage is properly calibrated for even heat distribution.
Soldering:
Set Soldering Parameters: For each PCB, set the appropriate soldering time, wave height, and soldering speed. Some models, such as the FS-250C, allow you to customize settings for each soldering point.
Monitor the Wave Soldering Process: Ensure the soldering wave is stable and adjust if necessary.
Post-Soldering:
Inspect the Soldering: Check the quality of solder joints for consistency and precision. For some models, you can monitor real-time data to ensure ideal soldering conditions.
Clean and Maintain: After each cycle, clean the solder pot and flux application areas to ensure optimal machine performance.
Maintenance and Troubleshooting:
Routine Maintenance: Regularly check and maintain components such as the flux sprayer, preheating modules, and pumps.
Troubleshooting: If issues arise, refer to the troubleshooting guide in the manual, or consult our customer support team for assistance.
