Pneumatic Stencil Cleaning Machine for Solvent Spray Cleaning | DEZ-C780

The DEZ-C780 Pneumatic Stencil Cleaning Machine removes solder paste, red glue, flux and other printing residues from SMT stencils and screen meshes.

Two stencils measuring up to 750mm × 750mm × 40 mm can be cleaned in one cycle. Double-sided rotating spray nozzles deliver cleaning solvent to both stencil surfaces and through fine apertures, followed by compressed-air drying inside the same chamber.

The machine operates entirely with compressed air. It does not require electrical power or a water supply for the cleaning process, making it suitable for factories that use solvent-based stencil cleaning and want to avoid a separate rinsing stage.

Key operating data:

  • Two stencils per cleaning cycle
  • Maximum stencil size: 750mm × 750mm × 40 mm
  • Cleaning time: 2–4 minutes
  • Drying time: 2–5 minutes
  • Three-stage solvent filtration
  • Fully pneumatic operation

Clean Blocked Apertures Before They Affect Printing

Solder paste and adhesive left inside stencil apertures can dry or accumulate between production runs. If these deposits are not removed completely, the next printing process may produce:

  • Insufficient solder paste deposits
  • Uneven paste volume
  • Blocked fine-pitch apertures
  • Poor printing around BGA and QFN pads
  • Solder bridging or open joints
  • Repeated manual wiping and stencil rework

The DEZ-C780 uses a 360° rotating, double-sided equal-pressure spray system to reach both stencil surfaces and force cleaning liquid through the apertures. It is intended for complete offline cleaning after production runs, product changeovers or extended stencil storage—not simply surface wiping during printing.

Applications of the Pneumatic Stencil Cleaning Machine

Solder Paste Stencil Cleaning

Used after SMT printing to remove solder paste remaining on stencil surfaces and inside apertures. This helps prevent dried paste from affecting deposit volume during the next production run.

Red Glue and SMT Adhesive Stencil Cleaning

Suitable for stencils used to print SMT adhesive before wave soldering or component fixation. The high-pressure spray helps remove adhesive residue that is difficult to clean using manual wiping.

Fine-Pitch Stencil Cleaning

Fine-pitch apertures used for BGA, QFN, CSP and other small-pad components are more easily blocked by dried paste. Double-sided spraying pushes cleaning liquid through the openings instead of cleaning only the outer surface.

Screen and Mesh Cleaning

The machine can also clean compatible metal screens and printing meshes when their dimensions, materials and residues are suitable for the selected cleaning solvent.

Industries Using Pneumatic Stencil Cleaning

Automotive-Electronics-SMT-1
Automotive Electronics
Automotive controllers, sensors, lighting modules and power boards require consistent paste printing. Thorough stencil cleaning helps reduce print variation caused by partially blocked apertures.
Consumer Electronics PCBA
Consumer and Mobile Electronics
Dense layouts and small component pads rely on clean stencil apertures to maintain solder paste volume. The DEZ-C780 helps remove residue from fine-pitch and high-density printing stencils.
Industrial Control SMT
Industrial Control Electronics
Stencils used for control boards, power modules and mixed-size components may contain both small apertures and larger openings. Double-sided spraying removes residue across these different aperture sizes.
LED & Power Electronics
LED and Power Electronics
LED boards often contain repeated small pads across a large printing area. Even contamination across the stencil can affect solder paste consistency over the entire panel.
EMS & Contract Manufacturing
EMS and High-Mix Electronics Manufacturing
Frequent product changeovers require stencils to be cleaned quickly before storage or reuse. Cleaning two stencils in one cycle reduces waiting time between production orders.

FAQs by DEZ-C780

Can the DEZ-C780 clean two stencils at the same time?

Yes. It supports up to two stencils measuring 750 × 750 × 40 mm. Custom sizes can be evaluated separately.

The DEZ-C780 is pneumatically operated and uses an external compressed-air supply. No electrical power is required for the normal cleaning process.

No. It uses compatible cleaning solvent followed by compressed-air drying, so no water-rinsing stage is required.

Yes, provided that the selected cleaning solvent is compatible with the adhesive residue and stencil material. Sample testing is recommended for cured or difficult adhesive deposits.

Cleaning takes approximately 2–4 minutes, while drying takes approximately 2–5 minutes. Actual time depends on the residue, stencil condition and selected process settings.

Yes. The liquid passes through 10 μm, 5 μm and 1 μm filters before recirculation. The solvent must still be replaced when contamination reaches the applicable process limit.
