AC620 Offline PCBA Cleaning Machine: Best Solution for Thorough Flux Residue Removal in SMT Assembly (2026 Guide)

Spertar AC620 Offline PCBA Cleaning Machine for flux removal

Description

Discover the Spertar AC620 Offline PCBA Cleaning Machine – a powerful, cost-effective solution for removing rosin, no-clean, and water-soluble flux from BGA, CSP, QFN, and SIP components. Ideal for medium-batch electronics manufacturers in China and worldwide.


Introduction

In today’s high-reliability electronics manufacturing, PCBA cleaning is no longer optional — it’s essential. Residual flux can cause shorts, corrosion, and field failures, especially on complex packages like BGA, CSP, QFN, and SIP.

The Spertar AC620 Offline PCBA Cleaning Machine is designed specifically for manufacturers who need powerful, flexible, and efficient cleaning without investing in a full inline system.

Whether you run medium-batch production or handle mixed board types, the AC620 delivers professional-grade flux removal while keeping operating costs low.

What Is the AC620 Offline PCBA Cleaner?

The AC620 is a batch-type (offline) aqueous cleaning system built for SMT PCBA post-reflow flux cleaning. Unlike manual cleaning or ultrasonic-only systems, it uses high-pressure spray technology combined with precise chemical control to achieve excellent cleanliness levels on even the most challenging components.

Key Target Applications:

  • Automotive electronics
  • Medical devices
  • Aerospace
  • Consumer electronics with high-density BGAs and QFNs
  • Contract manufacturers handling varied batch sizes

Top Features & Benefits of the AC620

  • Effective Flux Residue Removal: Thoroughly cleans rosin flux, water-soluble flux, and no-clean flux residues.
  • Advanced Spray Cleaning Technology: Multi-angle high-pressure spray reaches under BGA, CSP, and QFN packages where flux often hides.
  • Multi-Stage Process: Typically includes wash → rinse → final rinse → hot air drying for spotless, dry boards ready for conformal coating or testing.
  • Batch Flexibility: Perfect for small-to-medium production runs and frequent product changeovers.
  • User-Friendly Operation: PLC control with touch screen interface makes it easy to program and monitor cleaning cycles.
  • Energy & Chemical Efficient: Optimized tank design and filtration system reduce chemical consumption and waste.
  • Robust Build: Made with high-quality stainless steel (SUS304) for durability in demanding factory environments.

Why Choose Offline Cleaning Like the AC620?

Inline cleaners suit very high-volume lines, but for most manufacturers, offline PCBA cleaning machines offer better ROI because:

  • Lower initial investment
  • Smaller footprint
  • Easier maintenance
  • Greater flexibility for different board sizes.

Technical Highlights

  • Effective cleaning of SIP, BGA, CSP, QFN components
  • Hot air drying system for moisture-free results
  • Multiple liquid tanks with heating and filtration
  • Low consumption of cleaning agents and DI water
