1. Overview of TB-350 Fully Automatic Touch Brush Type PCBA Single-Side Cleaning Machine The 
equipment uses the online transmission technology and the touch brush method to clean the flux residue on the wave soldering surface of the PCBA, rinse with DI water, and dry it with hot air. The cleaning process has high cleaning cleanliness, which perfectly replaces manual labor and greatly improves cleaning efficiency. 

 

Features:

• The equipment is specially designed for flux removal after wave soldering, replacing manual brushing, improving cleaning productivity and cleanliness, and reducing cleaning costs;
• The equipment perfectly combines PCBA online transmission, efficient brushing, and water-based cleaning technologies;
• A revolutionary change has been made to the traditional solvent-based manual cleaning method, the introduction of a safe and environmentally friendly water-based cleaning solution, and a fully automatic cleaning mode, which avoids the operator's intimate contact with chemical liquids;
• After multiple processes of brushing, rinsing and drying, the flux residue on the PCBA after soldering can be removed efficiently without wetting the front components;
• The unique combination of roller brush and flat brush cleans from both directions of X and Y, which completely eliminates the dead angle of cleaning and fully guarantees the cleanliness of cleaning. Even the most stubborn hand solder joint residues can be completely removed in one go;
• The track width can be adjusted steplessly, which can adapt to PCBA of different widths;
• The transportation speed and brushing frequency are steplessly adjustable, and the cleaning process can be easily controlled;
• Filter system pressure monitoring and liquid conductivity real-time monitoring, providing intuitive and quantitative filter element and liquid replacement timing;
• Visual observation window, the process flow is clear at a glance;
• After connecting to wave soldering, it can realize fully automatic online cleaning.
