Four fixed spray rods spray aqueous cleaning liquid while the stencil moves forwards and backwards by motor.
Four fixed spray bars rinse with DI water; real-time 1 µm filtration keeps solder paste balls out.
Four hot-air blades dry the stencil; a 5.5 HP blower shortens dry time.
The hidden cost of manual stencil cleaning
Blocked apertures and wasted liquid are taxing your line
Every stencil with residue and every drop of wasted cleaning liquid costs money. An electric stencil cleaner changes that math.
Solder paste balls return
Without real-time filtration, solder paste balls wash back onto the stencil and re-contaminate boards.
Blocked apertures
Residue in stencil apertures causes paste misprint and rework.
Soft hoses wear out
Bending liquid and air hoses on moving spray heads fail and leak frequently.
Long dry times
Weak drying slows the stencil changeover between jobs.
Plastic pipes contaminate
Plastic liquid pipes risk contamination and corrosion in cleaning chemistry.
Manual results vary
Hand-cleaning quality depends on the operator, batch and shift.

Return on investment
What automated stencil cleaning is worth
Worked example for an EMS line cleaning stencils by hand today.
Solder paste balls returning to the stencil with real-time 1 µm filtration.
Operator per shift freed from manual stencil scrubbing.
Less dry time with the 5.5 HP hot-air blower (reference estimate).
Typical payback for a stencil cleaner on a mid-size line (reference estimate).
ROI figures are planning estimates based on reference EMS lines; actual payback depends on stencil volume, liquid cost and quality targets. We calculate a line-specific payback with your numbers during the consultation.

Installation guide
Install and commission the SME800
Reference procedure for an electric stencil cleaner. Full documentation ships with the machine.
Place the machine on a solid, flat, clean floor with enough space for installation, spare parts and maintenance.
Connect power per the nameplate, DI water supply (30–60 L/min open loop reference) and drainage; connect the exhaust vent.
Fill the cleaning liquid and water tanks; check the 1 µm filters for cleaning and DI water.
Check spray rods, air blades, pumps and valves; confirm the stencil transport moves freely.
Load a stencil, set the cleaning parameters, press start and verify the clean-rinse-dry result.

Technical evaluation FAQ
Questions buyers ask before ordering
What does the SME800 clean?
Solder paste stencils, red glue stencils, resin and copper masks, and misprint PCBs, using aqueous cleaning liquid followed by a DI water rinse.
How does the cleaning process work?
The stencil moves forwards and backwards by motor while four fixed spray rods spray aqueous liquid, then four fixed bars rinse with DI water, then four hot-air blades dry it.
What size stencils fit?
Stencils up to 750 mm (L) × 750 mm (W) × 40 mm (H) are supported.
How is contamination prevented?
Real-time 1 µm filtration on both the cleaning liquid and DI water keeps solder paste balls from returning to the stencil and re-contaminating boards.
Why is drying fast?
A 5.5 HP hot-air blower with four air blades delivers a high air rate, greatly reducing dry time between jobs.
How do I get a price and delivery time?
