Core Features

Captures particles ≤ 2 µm High-tack silicone head grips dust, copper shavings, fibers, and particulate that brushes and air guns miss.

Anti-static & non-contaminating ESD-safe formulation prevents charge buildup. No shedding, no rust, no chemical migration - safe for bare dies and display panels.

Self-cleaning with sticky pad Roll the tip across a sticky cleaning pad to restore full tack. One pen lasts months with regular pad maintenance.

Moisture-proof & aging-resistant Silicone compound stays pliable and tacky under humidity. Surface hardness remains stable across temperature cycles.

Three tack levels, two tip sizes Choose High / Medium / Low adhesion and 5 mm flat or pointed tip to match the task - from wide PCB sweeps to pinpoint rework.

Application Scenarios

SMT line inspection & pre-soldering cleanup

Sweep the flat 5 mm tip along pads and vias before paste application. The high-tack version lifts stray solder balls and copper dust that cause bridging defects - without disturbing neighboring components. Recommended: High tack · 5 mm flat tip

Screen lamination prep

Before applying OCA film or protective glass, use the pointed tip to lift individual dust specks from the display surface. Medium-tack silicone won't mark soft optical coatings or ITO layers. Recommended: Medium tack · Pointed tip

Camera module & lens assembly

Optical assembly rooms demand sub-5-µm cleanliness. The low-tack pen picks lint from lens barrels and CMOS sensor holders without static discharge risk - critical where even 1 µm of contamination causes a dark spot in the final image. Recommended: Low tack · Pointed tip

Cleanroom general maintenance (ISO Class 5–7)

Station the pen at every workbench alongside a sticky cleaning pad. Operators roll off contamination between component placements rather than reaching for compressed air - which scatters particles rather than removing them. Suitable for all tack levels · Daily-use setup

Real-Use Examples

Smartphone display factory - Reducing screen lamination rejects A display assembly line was seeing a 3–4% reject rate from dust inclusions under OCA film. By introducing the medium-tack pointed pen as a final-check step before film lay-down, inspectors could remove visible particles spotted under UV light. The pinpoint tip made it practical to act on a specific speck without repositioning the panel. Defect rates dropped within the first production week.

PCB rework station - Clearing solder ball scatter after hot-air rework After BGA rework with a hot-air station, micro solder balls scatter across the board surface. Brushing risks shorts; air guns can carry particles under other components. The high-tack flat pen collects scatter in a single controlled sweep. Because the silicone doesn't charge the board, there is no secondary ESD risk on nearby unpopulated ICs.

Care & Storage

After each use

Roll the tip on a sticky cleaning pad 3–5 times
Inspect the tip for embedded hard particles
Replace the pad when it no longer picks up debris from the pen

Storage

Keep in original clean, sealed packaging

Store away from benzene solvents, inks, and curing agents

Room temperature preferred; avoid direct sunlight

Do not

Clean with alcohol or solvent wipes

Press the tip against abrasive surfaces

Store uncapped near adhesives or uncured resins

Frequently Asked Questions

Q: How do I restore tack when the pen feels less sticky?

A: Roll the silicone head back and forth across a sticky cleaning pad 3–5 times. The pad surface pulls accumulated particles off the silicone and resets the exposed adhesive layer. Tack returns immediately - no solvents, no waiting.

Q: Can the pen be used directly on bare CMOS sensors or gold bond pads?

A: Yes - use the low-tack version. The silicone compound leaves zero residue and generates no triboelectric charge that would damage sensitive junctions. Avoid the high-tack version on bare sensor surfaces, as the stronger pull can displace wire bonds on fine-pitch devices.

Q: Will the pen work in a high-humidity environment?

A: Yes. The silicone formulation is moisture-resistant by nature - tack is not significantly affected by relative humidity in typical manufacturing ranges (30–70% RH). Store pens in clean, sealed packaging away from aromatic solvents and curing agents, which can degrade silicone over time.

Q: How many pens come per pack, and can we order custom quantities?

A: Standard packs contain 10 pens. Custom quantities and packaging - including individual blister packs, color-coded kits by tack level, or bulk trays - are available on request.

Q: What chemicals should I keep the pen away from?

A: Keep away from benzene-based solvents, ink and dye solutions, and curing agents such as peroxides. Contact with these can swell or degrade the silicone head and permanently reduce tack. Store in the original clean packaging between uses.
