ESD Mat Testing

12/04/2012 10:32 AM

We are looking to test our ESD mats, I see some surface testers have weights and others don't. I understand the basic idea more weight makes better contact but am wondering how critical is it to test with weights?

How will you test them?

If you have no written procedure that specifies the test conditions, why bother?

Do the testers not come with instructions?

You should adopt some type of test procedure, or you are wasting your time.

I'd read this carefully:

ESD Control Program Periodic Verification - Protektive Pak - Desco

Fred Tenser and Gene Felder are only identified as working for Desco (a company that sells these products, not necessarily experts in the field {sales men?}) it makes sense they would recommend using as many of their products as possible this does not mean it is "best practices", thus a post in a forum looking for input from others doing this work.

1 Connect the mat's grounding clip to the electrical ground connection. You can use grounded metal conduit or a cold water pipe for an electrical ground.

2 Turn the mat test meter on. Clip one probe to the mat's metal snap or grounding point. Touch the other probe to the furthest point on the mat's surface away from the grounding point. A good mat will either light up the meter's "good" light or indicate a resistance of between 1 million and 10 billion ohms.

3 Move the 2-meter probes to opposite ends of the mat, touching the mat's surface. The meter should read a consistent resistance of more than 1 million ohms. Move the probes to a different point on the mat's edge, always keeping them at opposite sides. The meter should continue to show a resistance between 1 million and 10 billion ohms, or light its "good" light.

none of the replies addresses the question asked, of weight vs no weight
