1. The Industry Shift: Why Aqueous Cleaning is Replacing Traditional IPA?
In the SMT industry, as components become increasingly miniaturized (such as 01005, BGA, and QFN) and reliability requirements soar, traditional manual wiping with Isopropyl Alcohol (IPA) is no longer sufficient. Not only is the cleanliness difficult to quantify, but it also poses fire hazards and environmental compliance pressures.
The DEZ-C743S Dual-Chamber Offline PCBA Cleaning Machine from DEZSMART is specifically engineered as a “precision striker” for small to medium production capacities and high-accuracy cleaning needs.
2. Core Advantages: Not Just Cleaning, But an Efficiency Leap
Dual Chambers for Doubled Capacity: Unlike common single-chamber machines, the DEZ-C743S features a dual-chamber, dual-layer design with a cleaning basket size of L610*W560*H100 mm. This allows you to process more products simultaneously or set different process flows in each chamber, significantly boosting output per unit of time.
Scientific Spray Design to Eliminate Blind Spots: High-density PCBAs often suffer from residue trapped under components. We utilize a horizontally increasing and vertically staggered nozzle distribution. Combined with 360° rotating spray technology, this ensures the cleaning agent penetrates the tiny gaps under BGAs.
Adjustable Precision: The spray pressure is adjustable between 30-70 psi, ensuring thorough cleaning without damaging delicate, small-sized components.
Military-Grade Cleanliness Standards: The DEZ-C743S achieves ionic contamination levels that fully comply with IPC-610D Level III standards (less than 1.56ug/cm²) and the U.S. Military Standard MIL28809 Level I. It effectively removes water-soluble residues, RMA rosin, lead-free flux, plating salts, and dust.
3. Closed-Loop Process: Intelligent “Hands-Free” Operation
This machine integrates chemical washing, DI water rinsing, and powerful hot air drying into one compact unit.
Fully Automated Control: Equipped with a PLC and a user-friendly touchscreen, operators simply load the material and select a pre-set program.
Automatic Proportioning: The system supports an automatic mixing ratio of 5%-25% for DI water and chemical liquids, eliminating manual calculation errors.
Process Visualization: The spray chambers feature large observation windows and dual LED lighting, making the cleaning process transparent at a glance.
4. Eco-Friendly and Low Operational Costs
The DEZ-C743S was designed with “chemical conservation” in mind.
Closed-Loop Recycling: The cleaning fluid is filtered through a 0.45um system to intercept micro-contaminants like solder paste and flux, allowing the liquid to be recycled.
UltraPure Water Integration: We offer an optional 0.5 T/H Ultra-Pure Water System that ensures the rinsing water consistently stays above 15MΩ for optimal results.
FAQ:
Q1: Can the DEZ-C743S handle different types of flux residues? A: Yes. The system is highly versatile and can effectively remove a wide range of residues, including water-soluble flux, RMA (Rosyn Mildly Activated), no-clean lead-free flux, plating salts, and even finger prints or dust.
Q2: How does the machine protect sensitive components from high-pressure damage?
A: We have implemented a pressure-adjustable nozzle design (30-70 psi). This allows users to lower the spray intensity for delicate or small-sized components to prevent splashing or physical impact damage while maintaining cleaning efficiency.
Q3: Is the maintenance of the spray and piping system complicated? A: Not at all. The DEZ-C743S features a human-centric design with quick-connect fittings for both the spray bars and the water pipes. This makes inspection, cleaning, or replacement of parts fast and easy, minimizing production downtime
