Why This Swab

Heat-sealed, not glued. The fiber head is fused to the PP stem by heat-press, so there's no adhesive layer to leach solvent residue or peel loose under repeated wiping.
Head stays put, cleaning stays consistent. Because the fiber is heat-bonded, the head resists fraying and shedding even after multiple passes across a lens or PCB surface.
Cleanroom-washed and packed. Fiber heads are processed and vacuum-sealed inside a Class 10–100 cleanroom, keeping the particle count on the swab itself low before it ever touches your part.
Broad solvent compatibility. The wipe head tolerates a wide range of reagents and cleaning solutions, so one swab design covers most alcohol- and solvent-based wiping steps.
Color-coded and customizable. Handles come in green, blue, white, black, orange, and other colors on request - useful for separating swabs by process step, cleanroom zone, or solvent type to avoid cross-contamination.

Where It's Used

UV optics and lens assembly

A flat, fan-shaped head (WN0328) conforms to curved lens surfaces and coating edges, letting the operator clear residue from a UV lens or filter without pressing a stiff edge into the glass.

PCB and electronic component cleaning

The narrower, defined tip on WN1003 (13.5 mm width, 25 mm length) fits between densely packed components and connector pins - the kind of tight-clearance wiping typical in electronics assembly and rework lines.

Solvent and reagent wiping in cleanroom environments

Because the head is heat-sealed rather than glued, it can be dipped and worked with a range of alcohol- and solvent-based cleaning agents without the risk of adhesive breaking down and contaminating the wipe surface - a common failure point with glued-head swabs in repeated solvent-wiping steps.

Color-segregated process lines

Facilities running multiple cleaning steps (e.g., a flux-removal step and a final optical-clean step) can assign different handle colors to each stage, reducing the chance of a swab used for one solvent being mistakenly reused for another.

Frequently Asked Questions

Q: What's the actual difference between WN0328 and WN1003?

A: WN0328 has a flat, fan-shaped head on a blue PP handle, sized for broader surface wiping (lenses, flat optical components). WN1003 has a defined narrow tip (13.5 mm wide, 25 mm long) on a green handle, better suited to precision wiping around components and in tight spaces.

Q: Is the fiber head glued to the handle?

A: No. Both models use a heat-seal bonding process - the fiber head is fused directly to the PP stem, with no adhesive layer.

Q: What cleanroom class are these produced and packed in?

A: The wipe heads are cleaned and vacuum-packed in a Class 10–100 cleanroom environment.

Q: What can I clean with these swabs - is solvent compatibility an issue?

A: The polyester/microfiber heads are compatible with a wide range of reagents and cleaning solutions used in optical and electronics wiping. If you're using a specific aggressive solvent, confirm compatibility with us before large-scale use.

Q: Do the colors mean anything, or are they just cosmetic?

A: Color is mainly for identification - separating swabs by process step, department, or solvent type on a line. Standard colors are green, blue, white, black, and orange; custom colors can be produced on request.

Q: How are these packaged?

A: Standard packaging is vacuum-sealed bags of 10 pieces. Individual packaging is also available, and both packaging format and handle color can be customized for order volume.

Q: Can I get custom handle colors or head shapes for a specific process?

A: Yes, both handle color and packaging format can be customized. For a custom head shape or size beyond the WN0328/WN1003 specs, contact us with your application details.
