Desktop PCB Cleaner
Production / Service Use
Key Features (PCB Cleaning + Flux Removal)
- Flux Removal / Defluxing: Removes rosin flux and soldering contamination (process dependent for no-clean).
- Safe for SMDs: Non-contact cleaning reaches under SMD components and tight gaps.
- Repair + Production: Ideal for mobile PCBs, service centers, and electronics manufacturing.
- Heater + Timer: Controlled cleaning cycles for repeatable results.

Ultrasonic PCB Cleaner Machine
LeelaSonic manufactures Ultrasonic PCB Cleaning Machines in India for safe circuit board cleaning and flux removal (defluxing). These machines are used by electronics repair shops, service centers, and SMT assembly lines for consistent and repeatable cleaning.
Quick Summary (click to expand)
- Capacities: 2L to 30L
- Use cases: mobile repair, SMT assemblies, control cards
- Helps reduce: residues, corrosion risk, intermittent faults
Manual brushing cannot reach contamination trapped under SMDs. Ultrasonic cavitation penetrates micro-gaps and removes flux residues, solder balls, dust, ionic contamination and oxidation that can cause corrosion, leakage current or intermittent faults.
Applications
- Mobile Repair: Cleaning smartphone logic boards after water damage (iPhone/Android).
- SMT Assembly: Post-solder cleaning / defluxing after reflow or hand soldering.
- Rework Stations: Cleaning PCBs before and after component replacement.
- Industrial Electronics: Control cards, PLC boards, driver cards, power electronics boards.
- Preventive Maintenance: Removing dust/oil/flux deposits that cause shorts and corrosion.
- PCB Defluxing Guide: Read PCB defluxing / flux removal application notes
Recommended PCB Cleaning Process
- Pre-check: Remove batteries/speakers where required; follow device-specific safety.
- Cleaning Solution: Use PCB cleaning chemistry suitable for your flux type (rosin/no-clean/water-soluble).
- Ultrasonic Cycle: Short controlled cycles are better than long aggressive runs.
- Rinse: Proper rinsing reduces residues and improves reliability.
- Drying: Complete drying is essential (air knife / warm air / oven as per process).
For production lines and higher throughput, consider a Multi Stage Ultrasonic Cleaning System (wash + rinse + dry).
For correct model selection, share PCB size, quantity per batch, contamination type (rosin/no-clean), and your rinse/drying workflow.
Frequently Asked Questions
Yes, when the correct frequency, chemistry and process are used. Ultrasonic cleaning is non-contact and can remove flux and contamination from under SMDs without damaging components.
Use a dedicated PCB cleaning/defluxing solution for best results. IPA can also be used in controlled setups. The correct chemistry depends on flux type and your rinse/drying workflow.
Yes. Proper rinsing and complete drying improves reliability, reduces residues and avoids corrosion risks.
LeelaSonic PCB cleaning machines are priced from approximately ₹10,000 for the 2L desktop model to ₹65,000 for the 30L production model. Factory-direct from Dombivli — no dealer markup. Get a quote today.
Both terms refer to the same equipment. Smaller desktop models (2L–10L) suit repair shops and mobile service centres. Larger models (20L–30L) are used as PCB cleaning machines for SMT production lines and batch cleaning of control cards and assembled boards.
Yes. LeelaSonic ultrasonic PCB cleaner machines are widely used by mobile repair shops for cleaning smartphone logic boards after water damage — removing corrosion, oxidation and contaminants from fine-pitch SMD components. Use IPA or a dedicated mobile board cleaning solution.
