In my past we had used some ESD cloth covers over racks with CCA's.  CCA's were not Class 0.  Covers were over 5 sides, but I think the bottom was open.

I know a lot are off to APEX, but do any of you have any opinion of tray carts moving product on the production floor? Specifically in a low ESD sensitive environment?

Do covered carts offer any more protection than a open cart if it is well grounded and the product is on static dissipative trays?

Just trying to understand if I need to spend the extra money on a covered cart or not.

Thanks,

Steve
