Products Description
The SE-2000B fills the role of a dedicated small-batch benchtop ultrasonic cleaner for electronics R&D labs, PCB rework-processing stations, maker spaces, and university engineering departments. The 2-liter tank accepts standard 160 × 100 mm PCB panels, small PCB assemblyed part trays, and batches of SMD components in mesh baskets - fitting the throughput of a single engineer or technician working through daily prototype iterations. The unit's 175 × 160 mm footprint occupies less counter space than a typical oscilloscope, leaving room for a soldering station, hot plate, and microscope on a standard 1.2 m electronics workbench.
The ultrasonic generation system uses Soner's proprietary 40kHz piezoelectric transducer bonded directly to the tank base. This frequency produces fine cavitation bubbles (mean diameter 5–10 µm) that implode with low impact energy - strong enough to dislodge rosin flux residue from between component leads on populated boards, yet gentle enough to avoid delaminating FR-4 substrates or cracking polymer housings. The 50W ultrasonic power rating is calibrated for the 2L tank volume: sufficient cavitation density to clean populated PCBs in 3–5 minutes, but not so aggressive that fine-pitch QFP leads or 0201 SMD components are mechanically stressed. The frequency is also well below the resonance range of standard SMD packages, so PCB components do not experience mechanical stress during cleaning.
The integrated 60°C heater accelerates the breakdown of rosin-based flux, no-clean flux residue, water-soluble OA flux, and light oxidation on copper traces - the four primary contaminants that accumulate during PCB assembly, hand soldering, and reflow. Heating flux residue to 50–60°C allows saponification with mild alkaline cleaning solution in a fraction of the time required at ambient temperature. The control circuit holds temperature within ±2°C of the setpoint, preventing thermal shock to components and avoiding the warping of polymer connectors or PC housings that temperatures above 70°C can cause.

Products Advantage
40kHz fine cavitation - lifts rosin flux, no-clean flux residue, and solder paste from between component leads and BGA underfill edges without mechanical stress on 0201 SMDs or fine-pitch QFP leads; avoids the aggressive bubble collapse that 28kHz industrial units produce which can fracture solder joints and crack ceramic capacitors.
Stainless steel SUS304 tank - corrosion-resistant to rosin saponifiers, mild alkaline defluxers, and flux remover rinse; no ion leaching that could leave electrolytic residue on copper traces, aluminum heat sinks, or gold-plated contacts.
60°C controlled heating - accelerates flux saponification without the thermal risk to polymer connectors, plastic housings, or electrolytic capacitors that temperatures above 80°C cause; safe for ABS, polycarbonate, FR-4 substrates, and standard consumer-grade components rated to 85°C.
Compact countertop footprint - 175 × 160 mm base fits a standard electronics workbench alongside a soldering station, hot air rework station, and stereo microscope without displacing test instruments or a function generator.
Digital timer 0–30 min - enables consistent cleaning protocols across multiple operators and shifts; eliminates guesswork in flux removal, solder paste stencil cleaning, and SMD component prep.
Water-level sensor - prevents dry operation and transducer damage when operators run consecutive cleaning cycles between soldering batches without checking tank fill.
Soner-manufactured transducer - proprietary sandwich-structure bonding ensures consistent 40kHz output over the rated 10,000-hour service life; withstands daily prototype lab use without output drift or frequency shift that would compromise cleaning uniformity.

FAQ
Q: Is the SE-2000B safe for populated PCBs with SMD components?
A: Yes, at 40 kHz the cavitation is fine enough to clean under 0201 and 0402 SMD components, BGA underfill edges, and fine-pitch QFP leads without mechanical stress. Use a basket to keep PCBs off the tank bottom and avoid placing components directly against the transducer surface. Do not use acidic or chloride-based solutions on populated boards-these attack copper traces and solder joints. For double-sided boards with heavy components, place a small weight on top to keep the board submerged.
Q: What ultrasonic solution should I use for PCB flux removal?
A: Use a rosin-flux-specific saponifier (1–3% concentration in warm water) for RMA and no-clean flux, or a mild alkaline solution for water-soluble OA flux. For lead-free SAC305 solder paste residue, a higher-temperature (50–60°C) saponifier with an extended 5–8 minute cycle improves removal. Flux remover at room temperature works for light post-reflow residue but is flammable-never use flux remover in a heated tank above its 12°C flash point. For ionic contamination testing (per IPC-TM-650), use deionized water as the final rinse solution.
Q: Can I clean multiple small PCBs at once?
A: Yes. The SE-2000B's 2L tank and included basket can hold 3–5 small PCBs (50 × 50 mm to 100 × 80 mm) standing vertically, or 1–2 larger panels (up to 160 × 100 mm) flat. Arrange boards back-to-back with components facing inward to avoid contact marks. For SMD-heavy boards, allow at least 10 mm spacing between components and the tank wall to ensure cavitation penetration. For stencil cleaning, lay the stencil flat with the aperture side up and avoid stacking multiple stencils in the same cycle.
Q: What temperature should I set for different PCB cleaning tasks?
A: For rosin flux (RMA) removal: 50–60°C with saponifier and a 3–5 minute cycle. For no-clean flux: 40–50°C with a no-clean-specific defluxer, 4–6 minute cycle. For water-soluble OA flux: 40–50°C with DI water, 2–4 minute cycle. For lead-free SAC305 paste residue: 55–60°C with saponifier, 5–8 minute cycle. For general dust and pre-reflow cleanup: ambient temperature with a mild surfactant, 2–3 minute cycle. For stencil cleaning: 35–45°C with stencil-specific cleaning solution, 4–6 minute cycle.
Q: How long does the SE-2000B transducer last?
A: The Soner-manufactured PZT-4 transducer is rated for 10,000+ operating hours under normal use. At typical electronics lab use of 1–2 hours daily, this translates to 13+ years of service life. To maximize transducer life, avoid running the unit dry, use proper cavitation solution (not plain water for >50% of cycles), and decalcify the tank every 3 months if using hard tap water. Always refill the tank with fresh solution at the start of each shift-dissolved flux residue can re-deposit on PCB surfaces if the bath becomes saturated.
Q: What is the difference between SE-2000B at 2L and SE-6000B at 6L?
A: The SE-2000B is optimized for single-station electronics workbench use-small footprint (175 × 160 mm), 50W power, 60°C max heat, 30-min timer-suited to one engineer running daily prototype iterations. The SE-6000B is a higher-throughput unit for shared lab or production use, with 180W power, 80°C max heat, a 24-hour timer, and a 6L tank that processes 4–6 PCB panels in a single cycle. For multi-station labs or small-batch production, the SE-6000B reduces cycle time per project.
Q: Is the SE-2000B CE / FCC certified for North American and European imports?
A: Yes. The SE-2000B carries CE (European Union), FCC (United States), RoHS (environmental compliance), and KC (South Korea) certifications as standard. Full documentation, including test reports, declarations of conformity, and material safety data sheets, is provided with each shipment for customs clearance and end-customer compliance audits.
