Advanced Cleanroom Garments
by TW Clean, Inc.
Objective
Discuss the need for ESD Control in a cleanroom environment
Review the existing priorities for cleanroom garments
Discuss new methods to enhance ESD Control while dramatically limiting cost and maintaining the stringent Contamination Control levels
Typical Priority of ESD Control
ESD Control is considered a lower priority relative to Contamination Control
The Justification:
There is an obvious negative effect when sacrificing control of particulate contamination to control the effects for static electricity
Actual Priority of ESD Control
ESD Control is as important to the process as Contamination Control
The Truth:
ESD is a contaminant that will cost you millions
Newer ESD Control technologies are designed to be consistent with or exceed the current requirement for contamination control
Ground Zero ESD Control Garments
One garment can deliver superior ESD and Contamination Control performance
The Product:
Exclusive fabric combined with patented grounding technology provide the best protection ever from a cleanroom garment
Meeting the ESD Control Needs
Ground Zero limits the voltage generated by operators
Other garment systems don’t measure up
Variables in Garment Performance
Shoes worn under the garment
Clothing worn under the garment
Fit of the garment
Type of chairs used
Hair style
Tribo-Charging
Any time two materials make contact and separate there will be an exchange of electrons
This exchange results in the charging of both materials
The magnitude and polarity of the charge is dependent upon the types of material
Limit the Impact of Variables
Ground Zero limits the impact of variations in footwear
Other garment systems don’t measure up
Electrostatic Attraction
Like a giant magnet, an operator wearing a garment that holds a charge will carry particles throughout the cleanroom
Friction will change the nature of the charge and force the particles to fall back into the environment
Protect Your Investment
A major cost associated with cleanroom garments is testing, verification and auditing
Ground Zero garments exhibit an unsurpassed consistency in performance which in turn lowers administration costs.  Our warranty protects your investment
Our patented grounding technology is flexible enough to easily fit with existing test protocol
Ground Zero Grounding Options
Exclusive Fabric
Ground Zero fabric is an exclusive Twill Weave of Polyester and Carbon with a dual grid pattern at 7mm intervals
Ground Zero is available in 7 colors:
Improve Yield
It is a fact that ESD damage is responsible for stealing millions of dollars in profits each year
Yield enhancement is a process of fixing what is broken and eliminating what is not
Ground Zero garments work so well they can be continuously monitored, hence eliminated as a potential problem
Valuable time is then dedicated to isolating the many unknowns in the process
Key Benefits of Ground Zero
The confidence that the cleanroom garment is not having a negative impact on the process
The ability to dedicate resources to other issues and areas of concern
The Knowledge that TW Clean is standing behind the performance of Ground Zero Garments
Next Steps
Evaluate Ground Zero Garments
Determine ESD sensitivity of devices
Generate base line voltage generation data using existing garments
Conduct similar tests using Ground Zero Garments
Compare results
