1. Patent Pending ESG Strap Grounding Solutions Presentation by: Electro Static Technology

2. Copyright © 2002 Electro Static Technology Introduction Electrostatic charges will cause a variety of failures in electronic equipment due to electrostatic forces and electrostatic discharge. This presentation will cover the problems created by electrostatic charges along with cost effective solutions.

3. Copyright © 2002 Electro Static Technology Electrostatic Forces n Charged surfaces will attract or repel other charged surfaces due to electrostatic forces. n The effects of electrostatic forces are: –Material handling problems –Contamination problems

4. Copyright © 2002 Electro Static Technology Electrostatic Discharge n Static charges can build up to high levels. n An electrostatic discharge will result when the electric field between a charged surface and another part inside a machine exceeds the breakdown strength of air. n The breakdown strength of air is 3000 volts per millimeter.

5. Copyright © 2002 Electro Static Technology Electrostatic Discharge n The effects of electrostatic discharge are: –Electric shock to personnel (mild to severe) –Permanent damage to circuit components –Damage to interface displays (LED, LCD) –Damage to print heads –Latent damage to semiconductor junctions

6. Copyright © 2002 Electro Static Technology Electro Magnetic Interference n An electrostatic discharge will create a pulse of Electro-Magnetic Interference. n Electro-Magnetic pulses will interfere with data streams and microprocessor operation. n Electro-Magnetic Interference will also affect other electronics in the vicinity of the discharge.

8. Copyright © 2002 Electro Static Technology Metallic Grounding Straps n Traditional grounding straps are made of solid, stranded, or braided wire conductors. n Wire grounding strap assemblies are expensive to manufacture. n Wire grounding strap assemblies are difficult to handle and install on an assembly line. n Metallic grounding straps can fatigue and break if attached to articulating devices.

9. Copyright © 2002 Electro Static Technology Electrostatic Ground Strap n The ESG Strap is a one piece conductive film strip with mounting holes punched into each end. n The volume resistivity is 1 x 10 6 ohm-cm. n Electrostatic charges will drain to ground in a controlled manner. n The conductive film material is flexible and easy to route inside equipment.

11. Copyright © 2002 Electro Static Technology Electrostatic Ground Strap n The ESG Strap will not fatigue and break when attached to articulating devices. n The conductive film material is corrosion resistant and will not oxidize in the presence of moisture. n The ESG Strap is lightweight, durable, and easy to install on an assembly line.

12. Copyright © 2002 Electro Static Technology Electrostatic Ground Strap n The ESG Strap is available in three standard sizes: –6mm wide for M2 and #2-56 screws –8mm wide for M3 and #4-40 screws –10mm wide for M4 and #6-32 screws n The ESG Strap is available in any length from 25 millimeters to 1 meter.

13. Copyright © 2002 Electro Static Technology Safety Grounds n The ESG Strap is not designed to be used as a Safety Ground. n Follow the grounding requirements of the National Electrical Code if your application must be able to conduct uncontrolled currents to ground.

14. Copyright © 2002 Electro Static Technology Summary n Electrostatic forces will cause many problems in electronic equipment. n Electrostatic discharge can damage electronics and hardware. n Electro-Magnetic pulses will interfere with microprocessors and data transmission. n The ESG Strap is a cost effective solution to eliminating all of the above problems.
