The pink foam is ESD safe. I use the same CPU holders for all my CPU's. You don't puncture the pins through the foam. Just set the CPU on and close the clam shell. I folded my foam over once and just trimmed off the excess so it fits snug and doesn't slide around.

Nice packing ! Correct, only the black foam do you push the cpu into. The pink you either wrap or make a a layer it sits on.
BTW was in Eugene today for a building maintenance, smoke is as bad as in Salem and Portland. UGH !

The dense black foam is conductive to dissipate static charge. If you stick a multimeter in it I think it will read a few thousand ohms.
The pink stuff might be "antistatic" meaning that it's not prone to generate static on it's own, but I'm guessing it's not conductive and won't dissipate any charge that might be introduced.

That high density static dissipative foam is sold some places. I ordered some sheets of it from Jameco a while back, but it's kind of expensive. That's the kind of place where you might want to pile up a shopping cart for a while to economize on the shipping charge. On that point, I remember they had a good price on Kapton tape (at the time anyway).

Thank you for this guidance.

Mmm, I knew nothing about this.

I would be interested perhaps in replacing the pink stuff with the conductive or dissapative type if it seems to work and fit better.

🙁

Gettin' some rain tonight, if the smoke doesn't come right back in.

I've bought multiple sheets of the high density stuff on ebay....from a uk seller. Good stuff though.

Yeah, that was the stuff I bought. I used it in some small component drawers to hold all my DIP ICs when I decided to get rid of those long DIP tubes.
It holds the legs safely, not sure how important the static dissipative behavior is, but for something valuable I'd use it.

The black high density anti static foam is good for short term use, but for long term storage it is prone to decaying, and can be very difficult to clean off the pins.
