Ultrasonic Stencil Cleaner & SMT Cleaning Machine
LeelaSonic manufactures high-performance ultrasonic stencil cleaning machines for the SMT assembly industry in India. They are essential for zero-defect solder paste printing by clearing solder paste, red glue and flux residues from stencil apertures.
Unlike manual scrubbing or simple spray cleaning, LeelaSonic India uses controlled ultrasonic cavitation to gently yet thoroughly clean fine-pitch stencils, screens and misprinted PCBs—without disturbing delicate foil tension or mesh.

- SMT Stencils: Cleaning stainless-steel stencils (framed & frameless) for solder paste printing.
- Thick Film Screens: Removing conductive inks and pastes from mesh screens.
- Misprinted PCBs: Safely removing wet solder paste from expensive PCBs for reuse.
- Squeegees & Tools: Cleaning printing squeegees, spatulas and small accessories.
Used by SMT lines, EMS companies and PCB manufacturers across India to reduce defects and downtime. For populated PCB/flux cleaning, see our Ultrasonic PCB Cleaner.
Frequently Asked Questions
Yes. Ultrasonic action penetrates microscopic apertures, dislodging dried solder paste and red glue that manual cleaning cannot reach.
No. We use a gentle 40 kHz frequency and controlled ultrasonic power to avoid affecting foil tension and fine apertures.
