Custom Cleaning Brush
Disc Brush PCB
Disc Brush PCB provides controlled brush contact for precision electronics and static-control cleaning across contacts, slots, and boards. Working width, brush geometry, mounting, and fill are set around the machine path and the way lint, oxide, and flux residue must be released or carried away.
Product Features
Circular nylon face cleans PCB surfaces over a defined area — The disc removes loose dust and process particles without metal-wire contact.
Uniform tufting distributes pressure across the board — Filament height and density can be controlled to avoid isolated loading.
Fine bristles reach shallow texture and openings — Nylon tips clean around pads, holes, and board features.
Open zones can clear the center hub and fixtures — Tuft placement follows the machine path and board geometry.
Machine-specific mounting aligns the disc — Bore, holes, or holder features are produced from the approved equipment drawing.
Built for the PCB process — Disc diameter, nylon grade, trim, tuft pattern, backing, mounting, and contact setting can be customized.
Product Overview
Disc Brush PCB is used where repeatable contact is needed across contacts, slots, and boards rather than isolated hand cleaning. The active brush face clears lint, oxide, and flux residue while the holder, shaft, plate, or hub stays outside the interference path and supports the required working width. The brush must control contact load, particle shedding, conductivity, and access to fine features.
Key dimensions start with Brush head diameter 40–250 mm and Brush head length 100–1500 mm. The structure uses a roller or conveyor arrangement so the brush can follow a moving surface or machine path. The specified interface is shaft-mounted / flange. Nylon PA are the principal material directions in the current specification. Confirm the equipment model, shaft or hub interface, and actual operating speed; the brush does not use a universal speed rating.

Application Areas
Disc Brush PCB is primarily mapped to PCB Cleaning. Before applying the brush to another process, verify the surface, the route for removed debris, and the final finish target.
- Disc Brush PCB is best suited to PCB, copper-clad, ceramic substrate, MLCC carrier, and etching-line cleaning.
- The antistatic, conductive, PVA, abrasive, plate, disc, or precision roller brush follows copper surface, drilled holes, panel face, ceramic carrier, conveyor, and process rollers while the fill displaces oxide, solder balls, dust, resin smear, particles, and process residue.
- Use this configuration when the available access supports low-load contact on electronics, connectors, PCB, battery, ceramic, or semiconductor surfaces.
Selection Guidance
Structure fit
Match the roller and conveyor brush geometry to contacts, slots, and boards, the available access, and powered operation. Confirm Brush head diameter 40–250 mm and Brush head length 100–1500 mm against the complete working envelope before finalizing the brush.
Contact material
Choose from Nylon PA according to the behavior of lint, oxide, and flux residue, the surface sensitivity, and any wet, chemical, temperature, or hygiene requirements. Material is only one part of stiffness; filament diameter, exposed length, and density must also be confirmed.
When to use another solution
For Disc Brush PCB, use another cleaning method when lint, oxide, and flux residue cannot be released by controlled filament contact, when contacts, slots, and boards cannot tolerate the selected contact material, or when the access path prevents safe engagement and residue removal.

Frequently Asked Questions
How should Disc Brush PCB be selected?
Start with PCB, copper-clad, ceramic substrate, MLCC carrier, and etching-line cleaning, copper surface, drilled holes, panel face, ceramic carrier, conveyor, and process rollers, and oxide, solder balls, dust, resin smear, particles, and process residue. Then set PCB working width, Roller outside diameter, and Core or shaft diameter, choose the fill from the material and residue table, and match the mounting interface and operating condition.
Which dimensions define Disc Brush PCB?
The primary dimensions are PCB working width (100–1500 mm), Roller outside diameter (40–250 mm), and Core or shaft diameter (20–120 mm). Also provide the minimum clearance, working envelope, trim or engagement, and the existing holder, shaft, stem, thread, or handle.
Which filament or contact material is used for Disc Brush PCB?
The primary options are Nylon PA. The final choice follows surface sensitivity, residue adhesion, wet or dry use, temperature, chemicals, conductivity, and required cutting action.
When is Disc Brush PCB not the best cleaning method?
Disc Brush PCB is not the first choice for ionized air, vacuum, PVA sponge, megasonic, wipe, or solvent cleaning where bristle contact is unsuitable.
What information is required to quote Disc Brush PCB?
Send the part or machine drawing, photos of copper surface, drilled holes, panel face, ceramic carrier, conveyor, and process rollers, PCB working width, Roller outside diameter, Core or shaft diameter, and Filament or sponge grade, the residue description, wet or dry conditions, motion or use method, temperature, preferred Nylon PA, quantity, and the existing interface or sample.
