The ESD brush has developed over time to meet the specific needs for the electronics industry as well as industries where static electric buildup or charges are detrimental to the manufacturing process. The ESD brush line has been expanded to formally include cleanroom applications. Each category of brush is designed based on the elements you are working with, and the corresponding brush characteristics needed to perform the task at hand. Anti static brushes are made from low charging materials. Clean-room brushes are all heat tolerant and therefore autoclavable. See the following pages beginning with About ESD Brushes for detailed information on static electricity, its effects and how brushes can solve static buildup problems.
ESD (Electro Static Discharge) brushes provide manufacturers of electronics and static sensitive products the tools for cleaning and manufacturing that do not create static charges. A variety of brushes have been assembled over the years to meet the variety of needs associated with low charging (anti-static) brushes. Gordon Brush offers Conductive, Static Dissipative, or Insulative Brushes to fit your particular need.
Anti-Static Brushes and Static Electricity 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 low charging (anti-static). Low charging (anti-static) materials used to make these natural bristle 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.
ESD & Anti-Static Brush Applications General applications for any brush are: Applying, Pushing, Removing, Cleaning, Spreading, or acting as a Barrier. Specific uses for Anti-static & ESD Brushes include:
Board Prep Board Rework
Lead Trimming Rework
Edge Connector Cleaning
Static Dissipation and Wiping
The Thunderon Advantage Why Thunderon® fiber shows better performance compared with other material
1) Thunderon® fiber's conductive layer is a very thin layer incorporated on the outer surface of acrylic fiber which is already very fine in diameter among the available conductive fiber materials. Therefore, Thunderon® fiber is the finest conductive material available to promote Corona discharge.
2) Another factor is the physical property of Thunderon® fiber determined by the host acrylic fiber's characteristics. Compared with other widely used fibers like carbon or stainless fiber, the physical property of the Thunderon® fiber is much softer and has superior bend recovery if the fiber is in contact with charged material. Thus, Thunderon® fiber can be well maintained with original shape of brush compared to carbon fiber and stainless steel. This advantage prolongs the life of the brush.
Corona discharge is a very weak energy discharge from a static charged material to a fine conductive pin-like material near to the charged body. Corona discharge is improved if conductive material has the following characteristics:
Fine diameter material with sharp point;
High number of sharp conductive points;
Each point should be separated from another point thus forming a pitch;
Conductive point should be installed vertically to the surface of charged material.
3) The discharge capacity: In applications like printing or film roll processing, where static will be generated continuously, grounding is a must. When proper grounding is not provided, dissipation will drop significantly.
4) 5.85 x 10² Ω. cm
The numeric value is specific resistance. To convert the surface resistance/10 cm into the volume the method of calculation is as follows:
R x D ------------------- 9 x 105 x L x d
P = Specific Resistance R = Surface Resistance D = Denier L = Measure of Space d = Specific Gravity
