The LED Washing Machine SF-680 is an automatic online cleaning system designed for Micro LED and Mini LED manufacturing processes. The equipment is mainly used to remove water-soluble flux residues, organic contamination, and inorganic pollutants after LED chip soldering and assembly.

With the rapid development of Micro LED and Mini LED display technology, manufacturers require advanced cleaning solutions that can maintain high precision while protecting extremely small LED structures. The SF-680 provides a complete cleaning process combining DI water cleaning, DI water rinsing, and hot air drying.
The system is designed for high-precision, large-scale LED chip cleaning applications where cleanliness directly affects display quality, brightness consistency, and production yield.
What is LED Washing Machine SF-680?
The SF-680 is a fully automatic online water cleaning machine developed for Micro LED and Mini LED production lines.
Unlike traditional semiconductor wafer cleaners used in front-end chip fabrication, the SF-680 focuses on LED manufacturing and packaging processes after soldering or assembly.
Its main purpose is removing manufacturing residues from LED products before inspection, testing, or further packaging processes.
Why LED Chip Cleaning is Important
During Micro LED and Mini LED production, different processes can introduce contamination including:
Water-soluble flux residue
Organic contamination
Inorganic particles
Soldering residues
Process dust
These contaminants may affect:
LED brightness uniformity
Electrical performance
Display reliability
Bonding quality
Product lifetime
Effective cleaning is therefore an important step in improving LED manufacturing quality.
SF-680 LED Cleaning Technology
DI Water Spray Cleaning
The SF-680 uses heated DI water spray cleaning technology to remove water-soluble flux and surface contamination from LED components.
High-flow cleaning technology allows DI water to penetrate small gaps and remove residues from complex LED structures.
DI Water Rinse Process
After cleaning, the system performs DI water rinsing to remove remaining contaminants and maintain high surface cleanliness.
Long Time Hot Air Drying
The equipment integrates a long-duration hot air circulation drying system to remove moisture after cleaning.
Proper drying helps prevent water marks and prepares LED products for the next manufacturing process.
Adjustable Cleaning Parameters
Cleaning pressure, rinsing pressure, and air knife pressure can be adjusted according to different LED product requirements.
