content: Hey all,I'm thinking of picking up an ESD mat as I work on laptops a lot, I do use a wrist strap connected to earth as it is.Is this one alright?http://nz.rs-online.com/web/p/esd-safe-mats/7873114/They have a "pro" line thats 2x $$$, yet the pro line is all PVC and this one's rubber. Seems a bit out of place?Datasheet says it's rubber, dissipative top, conductive bottom. As far as I know that ticks all the boxes?I don't really know enough to not get misled, so I'd appreciate some input on this.

content: I don't own a esd mat and am novice familiar with esd standards....so take what I say cautiously (get real opinion).1. This is just the conductive layer (most have 2 or 3 layers, with dispative surface+conductive surface)2. The mat isn't s20.20 certified.3. The resistance is on the low side I think (low enough that I think many places would reject it). For ESD control, you want to remove charges....but not too quickly, because that in-itself can damage components. Also for personal safety reasons and you dont want it shorting or messing with your circuit (the point to point resistance on that mat is only 34K ohms!)http://nz.rs-online.com/web/p/esd-safe-mats/7873111/Not 20.s20 certified, but the resistances look a lot better to me

content: Thanks Chunky!Seems I was looking at the wrong datasheet before. The one I linked doesn't have the dissipative layer, so not worth the $50. Will have to look at getting the $100 grey one.Certifications not a big deal so long as it does the job.
