ESD (Electro Static Discharge) brushes provide manufacturers of electronics and static charge sensitive products the tools for cleaning and manufacturing that do not create static charges. A variety of anti-static brushes have been assembled over the years to meet the variety of needs associated with ESD buildup.

Our ESD brush line consists of conductive, static dissipative, low charging (anti-static brushes), insulative, and cleanroom brushes. All ESD brushes are designed based on the materials and applications you are working with. Numerous brush characteristics are available depending on the characteristics needed for your specific tasks. Our cleanroom brushes are all heat tolerant and autoclavable. See the information piece on Brushes & Static Electricity to determine which type of brush is best for your application.

ESD Brush Applications

General applications for anti-static brushes are: Applying, Pushing, Removing, Cleaning, Spreading, or acting as a Barrier.

Specific Uses for ESD Brushes and Cleanroom Brushes Include:

  • Solder Removal
  • Dusting/Dirt Removal
  • Board Prep Board Rework
  • Lead Trimming Rework
  • Edge Connector Cleaning
  • Static Dissipation and Wiping
  • General Cleaning

Sizes and Styles

The ESD brushes come in many styles and sizes, the most common styles resemble a toothbrush, pencil, or acid brush. Gordon Brush produces brushes that are conductive, dissipative, anti-static, insulative, and heat tolerant for clean room applications.

General Notes

To stiffen a brush, shorten the trim length or use a larger diameter bristle. To lengthen the life of a brush, use the softest fill material appropriate for the job.

Static charge (electricity) is a fairly simple, but often misunderstood event. Briefly stated, a static charge is generated between materials through friction, pressure or separation of two materials. This process is called the Triboelectric Effect [tribo means rubbing]. A material that inhibits the generation of static charges is classified as anti-static. Anti-static materials used to make brushes include Wood, Hog Bristle, Horse Hair and Goat Hair. These materials can be used in ESD sensitive areas as long as the brush remains in a liquid environment. In a dry environment, only conductive or dissipative materials should be used in ESD safe areas. You will find these classifications of brushes on the following links.

Standard ESD and Cleanrom Brush Categories

Conductive Brushes

Conductive brushes are made with materials that have a low electrical resistance, and generally have a surface resistivity range of 102 - 104. These brushes will easily and uniformly accept a charge and when attached to a grounding point, will provide a very rapid transfer to ground. This rapid transfer could be harmful to some electrical components.

Dissipative Brushes

Dissipative brushes are made with materials that have a surface resistivity of 105 - 1011, a higher resistivity than conductive brushes, but sufficiently conductive to permit controlled current flow. These brushes are excellent tools for removing static electricity, frequent use of dissipative brushes will keep electrostatic charges from building and will provide a slower, more controlled transfer to ground than a conductive brush. They are the only brushes recommended for use with Class 1 components.

Anti-Static Brushes

Anti-Static brushes (static charge inhibitor) are made from low charging and/or natural materials that are near neutral on the triboelectric chart. These brushes remain neutral because they neither give nor take electrons. However, there can be a slight charge created. Therefore, in extremely sensitive applications these brushes should only be used in a liquid environment. Only conductive or dissipative brushes should be used in an extremely sensitive, dry environment.

Insulative Brushes

Insulative brushes are made of materials that prevent the flow of electrons, and generally have a surface resistivity of 1012 - 1016. Any charge generated on the brush will remain there for an extended period of time. Insulative brushes are a less expensive alternative to anti-static brushes. They are best used in an environment where static is not critical or where the brush is submerged in a liquid when in use. Most brushes are made with non-conductive material and are insulative.

Cleanroom / Heat Tolerant


Custom ESD brushes are also available.
