Is your staff going to be wearing personnel grounding protection? The National Electrical Code defines a ground as: This ionizer also has a heater function. We use an esf system, which reduce this effect by a simple law of nature- charge cannot be created or destroyed in an isolated system.

Are there any environmental conditions to consider? Consider that the environment would be expected to be consistently wet.

We are wondering if ESD conductive or dissipative is best. I hope this helps address your question, please let us know if we can be of further assistance with any ESD questions or ESD protective product requirements you and your team may be sourcing. Our tile is specified as static conductive 2. Anti-Static refers to the ability to suppress charge generation or the prevention of static build up.

What should be the required Ground Rod-to-earth resistance? Let us know if we can provide you with flooring sample submittals, product specification sheets, quotations, etc. Are you fully operational and or will the work be done in phases? We need recommendations on conductive vs. The term antistatic typically refers to a range of resistance outside of industry accepted standards for ESD flooring. Based on what you have described in you e-mail, conductive range is best suited for your application, dissipative should not be considered.

ESD flooring systems are referred to as static conductive more conductive or static dissipative not as conductive, but will dissipate charges in an orderly fashion. The white or Neutral conductor comes from a neutral bus which is bonded to an earth grounding electrode and goes to an AC outlet receptacle.

If your process has technical personnel setting or standing at a workstation they DO require grounding via a Wrist Strap. Protective personnel grounding products such as; heel straps, booties and shoes working in conjunction with an ESD floor are designed for processes within your ESD program where the technician has to be mobile within an ESDPA, ESD Protected Area where the electrostatic sensitive device is not protected in an ESD protective container or shielded in some manner, e.

Will liquids or spills be anticipated or utilized in this area?

The auxiliary ground shall be bonded to the AC equipment ground when possible. Conductive ezd which reduce hazards that may result from static electricity buildup, and reduce the possibility of ignition of explosives and volatile chemicals. Keep in mind that smaller objects have lower capacitance and the time to discharge them maybe shorter than the discharge time.

Tile, we have many millions of square feet of experience in this category, so please call me when you have some time. Anti-static materials will not safely attract or decay a static charge before it randomly discharges.

The top layer would give the mats its resistance to chemicals, resistance to solder, flux, and the ability to keep it clean.

As you can see, the closer the bench top air ionizer effective distancethe lesser the decay time will be. We have an ESD tile floor in our testing lab. If your technical staff removes their wrist strap to transport an ESD sensitive device or component outside the ESD protected area, the device also needs to be shielded as well as the technician being properly outfitted with ESD shoes, booties or heel straps. This deals with induced potential on objects. Really close to the plates, the effects of decay time are linear and are affected by a plane source.

In selecting an electrical range there are several key factors to consider, these are in order esx importance x7 our professional opinion: Out of these 2 systems, a conductive epoxy is going to be most cost effective, verse a thermally heat welded conductive vinyl system.

You want to keep you flooring system clean and always below a gig ohm. What type traffic will the floor see?

Ionizers increase the electrical conductivity of air, which is especially useful in environments anxi use insulators which cannot be removed from the EPA such as PC boards. Anti-static is not the proper term to use for ESD flooring. Notice that voltages of up to 1. Compression resistance for the toe area of footwear. Does the type of work being performed in the protected area include, working with Power Supplies?

Thus, there is a small electric field generated which is zero at the work bench surface if dissipative ESD mats are being used and largest as you get closer to the ionizer.

Please let us know how we can better support you and your company moving forward, as your satisfaction is our highest priority!

The ESD vinyl flooring that we sell, service, and install is typically ahsi from a esdd conductive, non-humidity dependant blend of conductive additives interspersed with a pure virgin solid vinyl. We have a variety of bench and flooring mats and runners.

The black or Hot conductor comes from a circuit breaker and goes to an AC outlet receptacle. Our Duro-Stat line is actually a homogenous vinyl ESD matting with great mechanical and electrical properties.

Now things get complicated. I think this will give you some things to consider moving forward. How important is meeting industry standards to you and your company?

Puncture resistance of footwear bottoms. What is the difference between anti-static and static dissipative floors? Grounding of an ESD flooring system is comprised of appropriately placed copper grounding tape running beneath flooring overlayment adhesive and attached to primary electrical building grounds located throughout the facility, as well as installation of GZ- ground plates. These are the two most important criteria for recommending a system for this environment. We subscribe to the standard NFPA requirements for conductive flooring.

I would like to talk to you in greater detail regarding Epoxy vs.
