I'm in the middle of developing an ESD program at my company, trying to adhere to S20.20 as much as possible (and the suggestions of the ESD audit conducted before I got here).
I've been discussing the pros/cons of pink-poly foams and black foams. Both items are currently being used, and, as far as my rusty memory goes, this needs to change. I am, however, having some difficulty in explaining this to my boss, as I can't remember the details.
As I recall, pink-poly bags and foams etc are generally anti-static, that is...they resist the generation of static electricity. While the black foams and carbon impregnated bags are conductive/static-dissipative.
As I also recall, conductive/dissipative is better than anti-static. However, I'm having trouble articulating exactly why this is the case. Anyone have any advice for making this argument?
As a side note, we're also discussing the need for ground mats in the work area. Obviously benches that are being regularly used need ESD mats, but one argument that I'm losing is that if we're assembling boards on ESD safe foams, and transporting them on ESD safe trays/racks, why do I need an ESD mat on the benches. Assuming that the boards are not removed from their foams/transports onto the benches.
Thanks for any help/advice.
