IV.Frequently Asked Questions (FAQ)
Q1: What types of PCBA is the JEH-300C suitable for cleaning?
A:
The JEH-300C is designed for small-to-medium batch, high-reliability PCBA cleaning, including:
Removal of rosin/flux residues after SMT/DIP soldering
Solder paste residues, dust, and oils from assembly processes
High-reliability applications (automotive, medical, aerospace electronics)
R&D prototyping, rework boards, and flexible small-batch production
Q2: What are the advantages of aqueous cleaning vs. traditional solvent cleaning?
A:
Aqueous cleaning offers superior environmental, safety, and sustainability benefits:
✅ Eco-friendly: Low-VOC aqueous agents comply with RoHS/REACH regulations
✅ Safety: Non-flammable, reduces workshop hazards
✅ Compatibility: Gentle on most components, ideal for complex assemblies
✅ Cost efficiency: Lower consumable costs and simpler wastewater treatment
Q3: Can the JEH-300C clean PCBAs with underfill or sensitive components?
A:
Yes, with optimized protocols:
Adjustable spray pressure (0.5–2 bar) and temperature (RT–60°C) minimize stress
Submit samples for compatibility validation prior to full-scale cleaning
Avoid boards with unsealed electrolytic capacitors, mechanical connectors, or paper labels
Q4: How does the system ensure complete drying without water spots?
A:
Three-stage drying technology:
Powerful rinsing: Deionized water removes residual contaminants
Precision hot-air drying: Adjustable 40–80°C airflow penetrates component gaps
Uniform evaporation: Chamber airflow design eliminates moisture traps
Post-drying surface resistance >10¹⁰ Ω meets IPC cleanliness standards.
Q5: How is process consistency guaranteed?
A:
Full automation: PLC/touchscreen controls with preset cleaning/drying recipes
One-touch operation: Minimizes human error
Real-time monitoring: Temperature, pressure, and fluid parameters tracked; automatic fault alarms
