Dedicated ultrasonic cleaning machines for SMT solder paste stencils. Restores blocked, partially-blocked, and bridged stencil apertures in 5–8 minutes - replacing 15–30 minutes of manual wiping that still leaves paste in fine apertures. 28–40 kHz. Stencil holder fixture included. DI water rinse option. IEC certified. Exported to SE Asia, UAE, USA.
SMT stencil cleaning is one of the highest-frequency maintenance tasks in PCB assembly. Every stencil used for solder paste printing must be thoroughly cleaned before storage or reuse — blocked apertures cause insufficient paste deposits, leading to open circuits, tombstoning, and BGA voids. Manual wiping with IPA takes 15–30 minutes per stencil and still leaves paste residue in fine-pitch apertures below 0.4mm pitch.
Samarth Electronics' dedicated SMT stencil ultrasonic cleaner completes the same cleaning in 5–8 minutes, with every aperture confirmed clear — faster, more thorough, and operator-independent. The system includes a purpose-built stencil holder that maintains the stencil vertical in the cleaning tank for uniform aperture cleaning without frame distortion. DI water final rinse and hot-air drying complete the cycle.
Dedicated holder maintains stencil vertical — uniform aperture cleaning without frame stress or distortion.
Cavitation bubbles enter apertures as small as 0.3mm — removing paste from even finest-pitch openings.
3–4x faster than manual wiping — more stencil turns per shift without increasing cleaning time.
Integrated DI water rinse ensures zero ionic contamination from cleaning solution left on stencil.
Warm chemistry softens dry solder paste for faster, more complete dissolution in the cleaning bath.
Process meets IPC-7711/7721 stencil cleanliness requirements for controlled PCB assembly environments.
