Good Morning,

I need to know if the tubular plastic shelving (the type that you buy at big box stores for storage) could ever be grounded? We want to use it for ESD shelving but because its plastic/pvc I doubt it can ever really be grounded like a metal shelf.

Could someone post links to articles explaining the pro's or con's? Or give some insight on if this is a good idea or not?

Thank you, Luke

The fact that it is plastic means it is probably a static generator, which is a bad thing. It also being plastic means it cannot be grounded. We use Metro carts (see pic) with each shelf wired to the next and cart dragging a chain across ESD waxed floor.

Can the plastic shelving be used if the ESD sensitive material are in ESD safe bags? ESD safe containers? on ESD safe trays?

Thank you!

What do you call ESD safe bags? The pink poly bags are non charge generating but not static dissipative. The plastic can hold a localised charge and that can induce a charge separation in something you put on the plastic. So I think that means you can not put something in a pink poly ESD safe bag and put it on the plastic shelving.

You can buy ESD coating sprays but I don't know how effective they are. See if you can get them to cover the plastic pipes with copper tape. It will probably be too expensive but you can ask.

3 more questions I promise. :)

1. If a populated PCB is put on a ESD safe Rack, is it able to be placed on a Plastic Shelf?

2. If a populated PCB is put in a covered ESD box, is it able to be placed on a Plastic Shelf?

3. Could we put ESD vinyl mats on the plastic shelves and ground those?
