Boost SMT Yield with an Automatic Squeegee Cleaning Machine – SUBIT’s Proven Solution

In SMT printing, the squeegee blade is your most critical tool – and the most neglected. Dried paste, flux, and adhesive build up fast, rounding blade edges and causing uneven deposits, bridging, and costly defects. Manual wiping? Inconsistent, slow, and risky for delicate blade tips.
The data is clear: over 60% of SMT printing defects stem from poor stencil or squeegee maintenance. If you’re running 01005 components or fine-pitch BGAs, manual cleaning simply can’t deliver the repeatability you need.
Enter the automatic squeegee cleaning machine – a game-changer for yield and blade life.

How SUBIT Automates the Job Right

SUBIT’s fully automated SMT Squeegee Blade Cleaning Machine uses a 3‑stage process that eliminates guesswork:
Ultrasonic + high-pressure spray – 32 ultrasonic transducers and 24 spray nozzles, with a 360° rotating basket, penetrate microscopic residue that cloths leave behind.
Independent rinse – separate pump and filtration prevent cross-contamination.
Hot-air drying – 2.2kW fan + 1.2kW heater delivers dry blades, ready for reinstall.
Key specs (compact) :
Holds up to 6 blades (basket: 600×150mm, ~20kg load)
Wash/rinse/dry times adjustable (0–100 min each)
Spray pressure 0.1–0.5 MPa
304 stainless steel body, acid/alkali-resistant
Dimensions: 1305×1155×1352 mm, ~420 kg

What Makes SUBIT Different

Patented nozzle layout – upper and middle spray arms eliminate blind spots; easy to detach and clean.
3‑stage filtration (cleaning zone: 1mm screen, 50‑mesh bag, 0.45μm core) + separate rinse filtration – extends solvent life and cuts consumable costs.
Clear window & automatic door – full visibility during operation.
Built‑to‑last – all in 304 stainless, designed for harsh shop floors.

Best Practice Cleaning Schedule

Routine: every 4–6 operating hours
End‑of‑shift: always run a full cycle
For hardened or lead‑free paste: extend wash to 6–8 min and pre‑heat solvent to 50°C
Standard profile (fresh paste within 4h): 3 min wash / 2 min rinse / 5 min dry
Following this routine consistently extends blade life and slashes rework rates.
