S-6200 Nozzle Cleaning Machine: Cleaning the Bore, Not the Outside of the Nozzle

A 0201 nozzle that picks three boards and drops the fourth rarely trips an alarm — it just costs a mis-pick, a re-pick and a component on the floor. The usual reaction is to raise vacuum, not to look inside the bore. Flux vapour climbs the nozzle on every placement, cools, and narrows the aperture a few microns. By the time the pickup-error rate shows up in the report, the whole tray is affected. The S-6200 cleans that bore with water mist at 360 m/s.

The cost you haven't named

• The soil is inside the part; the wipe is outside it. Flux vapour condenses in the bore and on the vacuum seat. A lint cloth cleans the outer cone, and the restriction causing the mis-pick stays where it is.
• Pin-and-brush cleaning damages the nozzle it is meant to save. A cleaning pin ovals a 01005 bore, scratches the tip sealing face and marks the reflector panel the vision system reads.
• Nozzles become consumables because nothing verifies them. With no inspection step, a nozzle that picks poorly is binned and replaced, and the spend stays invisible in the spare-parts budget.
• Cleaning runs on habit, not on data. Trays get cleaned at changeover, or when someone remembers, while the pickup-error trend moved days earlier.
• A general-purpose bath is not a bore cleaner. Our S-100A ultrasonic bath and the S-1688, SME210/220 and SMM-1100 stencil cleaners were specified for other soils and geometries. A bore needs a process aimed at a sub-millimetre hole.

The Four-Step Nozzle Bore Audit

Buying a cleaner is the easy part. Specifying what "clean" means for your nozzle population is the work.

1. Segment the nozzle population by aperture. Group nozzles by bore size and by the component each one places. A 01005 nozzle accumulates restriction far faster than a Φ2.0 mm nozzle, so one schedule over-cleans one and leaves the other dirty.

2. Inspect the bore, not the tip. Look straight down the bore under the placement microscope before cleaning. Record which nozzles show crust, crescent residue at the seat or a damaged reflector panel — that record proves whether the process works.

3. Set the trigger from placement data, not the calendar. Pull pickup and pickup-error counts per nozzle position per shift. When a position drifts above its own baseline, that tray goes to the cleaner.

4. Verify after cleaning and log the result. Re-inspect the same bores after the cycle and record the pass. Without the after-check, "cleaned" is an assumption.

The vehicle: S-6200 Nozzle Cleaning Machine

The S-6200 holds nozzles and nothing else. Stencil and misprint cleaning belongs to the S-1688, SME210/220 and SMM-1100, assembled boards to the inline SME5600 and SME6200 washers, and loose parts to the S-100A bath. This is the bench unit you put a nozzle tray into, 24 at a time, to clear the bore with hydrodynamic water fragmentation instead of a soak, brush or pin.

• Segment by aperture → 01005 to Φ2.0 mm range, 24-hole jig. Fuji, Panasonic, Yamaha, Samsung and Juki nozzles sit in the same jig, each held in its own position, so a mixed batch is cleaned as one load.
• Inspect the bore → 360 m/s hydrodynamic water mist at ≤0.55 MPa. Water is fragmented into a fine mist at near-sonic velocity, so the cleaning action reaches inside a bore that no cloth, brush or pin can enter without contact.
• Trigger from data → PLC control with touch screen, 3–6 minute wash and 1–3 minute dry. No dedicated operator is required, so a tray can be cleaned as often as the error data says it should be.
• Verify and log → hot-air circulation drying, purified or DI water only, ≤150 cc/hour. Nozzles come out dry and ready for the microscope, with no film left by a cleaning agent and a consumption rate that keeps running cost predictable.

The stainless steel, anti-static structure suits a bench where nozzles are handled every shift.

Specification note: cycle time, jig configuration, spray pressure setting, liquid type and the power variant are confirmed at quotation, because they depend on your nozzle mix, bore sizes and supply standards.

The loop: re-qualify the tray every week

Run a weekly loop: take one tray cleaned that week, inspect all 24 bores under the placement microscope, and compare against the baseline photographs from commissioning. Log cycle count and water quality — DI conductivity drifts as the supply ages, and a mist process is sensitive to it. Feed the result back into the trigger: if bores come out clean while error rates still climb, the fault is vacuum, feeder or component supply, not cleaning. Re-run the Four-Step Nozzle Bore Audit whenever a new paste or flux is approved.

FAQ

Is this a stencil cleaner or a board washing machine?

Neither. Stencils and misprints belong to the S-1688, SME210/220 and SMM-1100, assembled boards to the inline SME5600 and SME6200 washers, and loose parts to the S-100A bath. The S-6200 holds nozzles only, in a 24-hole jig.

Can it clean 01005 nozzles without damage?

Yes. The stated range runs from 01005 up to Φ2.0 mm bore. Because the cleaning action is a water mist at ≤0.55 MPa rather than a pin, there is no abrasive contact with the bore or the tip sealing face.

What liquid does it use, and how much?

Purified water or DI water only — no solvent to buy, store or dispose of. At ≤150 cc/hour, a standard DI supply covers a full shift.

How long does a full cycle take?

Roughly 4 to 9 minutes for a loaded jig: 3–6 minutes of washing, then 1–3 minutes of hot-air drying. Exact times depend on soil level and nozzle type and are set at commissioning.

Will it affect nozzle coatings or reflector panels?

The process is non-contact and non-abrasive, so coatings and reflector panels are not mechanically worked. Confirm cycle parameters for your nozzle types at quotation and verify on a sample tray first.
