Excelta 212A-H Brushes - Anti-Static - Straight .13" X .13" - SS Handle/Horse Hair Bristles
Excelta 212A-H Anti-Static Brush — Straight 0.13" × 0.13", Stainless Steel Handle, Horsehair Bristles
The Excelta 212A-H is an anti-static precision cleaning brush with a fine 0.13" × 0.13" straight horsehair bristle head and a stainless steel handle. Designed specifically for ESD-sensitive environments, the 212A-H safely removes flux residue, dust, and debris from PCBs, SMT assemblies, connectors, and precision components without generating static charges that could damage sensitive devices.

Why Anti-Static Brushes Matter in Electronics Assembly
Standard brushes can generate significant electrostatic discharge (ESD) when dragged across PCB surfaces. Even brief static events below the threshold of human perception (<100V) can cause latent damage to CMOS, MOSFET, and other ESD-sensitive components — resulting in field failures that are difficult to trace. Anti-static brushes like the Excelta 212A-H use specially treated natural bristles that dissipate charge as they move, protecting devices during flux cleaning, inspection, and maintenance.

Frequently Asked Questions
Are the 212A-H bristles truly anti-static?
Yes — the horsehair bristles are treated to dissipate electrostatic charge rather than accumulate it. This makes them safe for direct contact with ESD-sensitive PCBs and components in ESD-controlled environments.
Can I use solvents with this brush?
The stainless steel handle is solvent-resistant. Horsehair bristles tolerate mild IPA-based flux cleaners but should not be soaked in aggressive solvents. Check solvent compatibility if using anything stronger than isopropyl alcohol.
What is the difference between the 212A-H and 212B-H?
The 212A-H has finer 0.13" × 0.13" bristles for detail work in tight spaces. The 212B-H has larger 0.32" × 0.25" bristles for faster general-area board cleaning. Both use the same SS handle and anti-static horsehair construction.
Is this brush suitable for cleanroom use?
Natural horsehair brushes generate minimal particulate compared to synthetic alternatives, making them appropriate for many cleanroom applications. Verify compliance with your specific ISO cleanliness class requirements.
How do I clean and maintain this brush?
Rinse bristles with IPA or appropriate cleaning solvent after use and allow to air dry bristle-side down or horizontally. Avoid storing bristle-side down under pressure. Replace when bristles become splayed or contaminated beyond cleaning.
