ESD Flooring | 23 February, 2006

for years we have all delt with the choices of endless products to use as flooring to create an ESD safe area for electronics assembly, I have spoke with "ESD TECH's" in the past that have told me a "clean / Bare concreate floor" provides as much dissapation of electrostatic charges as those $ 6.00 / sq.foot flooring systems. does anybody know this to be true? Is there writen documentation by an indapendant lab or firm that one could show to quality auditors.

and last but not least if one attempted validated the flooring internally what was the guidlines for testing? something like 2 pieces 1 lb ea. a foot apart "what is surface area of these 1 lb. items ?" with 1M or 100M read between them?

I know this may seem remeadial for many of you, but I'm just looking for the shortest path.

ie: mop the floors weekly and run a humidifyer or spend thousands on tile.

any thoughts?

You'll still have to mop the tiles bye the way to keep them clean. Instead of tiles I've used epoxy coating over concrete and used ESD wax. Had to clean floor and add wax about montly. We had one of those ESD floor testers to check. Epoxy floor was way less expensive than the tiles.

We went with the expensive tiled floors - look great until you try and move any machinery, & I still have nightmares about air skates.....

The epoxy, how is it holding up? high foot trafic? moving machines?

if it does crack or chip , just recoat the chiped area?

Thanks Bruce

Recently we did an installation in Germany. This company had their floor carpented with ESD carpet.

There is also ESD paint available.

Many regards,

Mark

I don't know of any data to support but I also believe that a concrete floor is just as good if not better than the money items. Have you ever left a fully charged car battery on you garage floor for any amount of time? She'll be dead.

If anyone has a floor tester it would be interesting if they could test some cement floor somewhere and tell us what happened

The principle issue with concrete is the charge dissipation as a function of water content.

Hi Russ,

We had a painted/waxed floor in one factory & a ESD tiled floor in the other. Both passed every audit (including telecoms & Japanese OEM's)that tested ESD etc.

Neither factory had issues with ESD damage to components either.

The tiled floor looked better, but needed far more effort to clean, and you needed to keep stocks of the conductive epoxy & floor tiles as hard rollers & air skates either ate or exploded tiles.

We have concrete floors. We check 28 locations every 90 days with a surface resitivity meter (calabrated) and Ive never seen a reading other than 10 to the 9th

We also use tiles for two reasons. 1 yes they look a lot better. 2. Customers don't buy into concrete floors as ESD safe.

Just have everyone where a smock. Seems to do little for ESD but everyone buys into it. Finger cots will add more flare as well. Wet concrete works the best for flooring, but seems to have a tendency to dry, thus losing it conductivity. Therefore, the cordless wrist straps are the only stop gap.

OK, ok, any chimp can be an "ESD Tech"- actually your first step is to identify your ESD needs. Know your product and then see where you actually need ESD protection. I see companies installing ESD tiles all the way thru shipping and yet not provide a simple jack for a wrist strap at repair stations. So when it comes to flooring, is this the only ESD protection that you'll have? If so, you may want to go a little over board. If everyone wears a wrist strap when working on product, your flooring almost becomes a mute point.

We use ESD carpeting and heel strap or conductive shoes. Works well since we tranfer a lot of product around by walking it from one station to another. Keeps the noise level down and knocks the sox off the customers.

My company is an ESD firm. I have tested many different floors and sell ESD flooring and other products. With that said, here are my thoughts. Unsealed concrete is porous and tests in the 10 6th-8th range here in the southeast where we have decent humidity. The floor will absorb the humidity and become somewhat conductive. A concrete floor that is sealed will typically read in the 10 to the 9th range. With that reading we do not generate a big charge but it becomes difficult to ground the operator through ESD footwear. ESD flooring is typically purchased as a marketing tool for their customers. It helps keep mobile operators grounded but it is not the most important part of an ESD program.

Thank you for these thoughts,

So Concreate floors, ESD wax, heal and wrist straps, in applicabe locations, grounded ESD mats at work stations, and smurf outfits. should do it ?

10 the the 6th 10M 10 to the 7th 100M big differance what is the target? at what distance?

Thanks again for all your help.

Bruce

If you are going for high margin business then you may want to ditch the blue smurf coats & go for white - they are a bugger to keep clean but look like you have a dedicated team of scientists. (Giving people clipboards & safey glasses helps complete the picture).

At my last jwob we avoided the white ones. Although very nice at first, the "heavier" guys never seemed to turn theirs in for cleaning. Thus we had the "dirty snowball" syndrome occurring that gave customers the opposite reaction we were hoping for. It's hard to explain those paste/adhesive/jelly/mustard stains surrounded by dirt. Ultimately, we would have to ask these folk to do stock count (count the number of boxes we have in the stockroom) every time a customer would tour. It was fun until management found out we were betting on them to Win, Place or Show on their box counts.

Hi,see you message on forum.

and you said you install a ESD flooring for a Germany company,I guess your company do the ESD antistatic products,and my company do this kind of products,do you have the interesting to buy them with good quality and competitive prices from a china manufacturer.
