i picked one of these^ up at a boot fair for £1.00....result.

i have 2x 24 drawer ones too...£12.00 each..

still not enough storage for everything though...

Lots of good ideas for storage containers. Storage containers are one thing, a work-around for anti-static foam within such storage bins is another...

wow i didnt know chips were so picky. I have all mine sitting in a drawer. I better put them into some foam when I get home.

I don't know man ... i have crazily high levels of humidity in my area so i am not afraid of static buildup at all ...

Some use aluminum foil.

I guess there isn't any around-the-house solutions that does what I want...i ordered this, which all in all isn't overly expensive so long as it does the task...thanks for the suggestions.

I bought the above foam, but it reads no resistance at all that I can tell. Bad sign, eh?

No resistance ? That's a good sign you know . Conductive really means conductive .

Haha...true, sorry.

I meant to communicate that it has infinite resistance...or, my DMM won't measure any resistance value at all...it's as conductive as air. $:-\$

You want zero to low resistance.

boogietone · February 16, 2012, 08:59:42 PM

I just measured some of the black stuff I got from mouser. The resistance was on the order of 5K over a 2mm distance.

This is the way it should be. You don't want low resistance since this would permit a high-current discharge. Most wrist straps used in manufacturing to ground the technician have a 1 megohm resistance. Wrist straps are grounded to the table (which is also moderately high-resistance) and get tested by technicians at the start of a shift. But if you have no conductive foam, aluminum foil is better than nothing, even with the current discharge risk.

What's your DMM ? Is it 2Mohm max ? If it is , then it's definitely working well . Even with a very high resistance , static will still discharge albeit at a lower current .
Because aluminium foil has a very low resistance and that would might cause a heavy discharge current which can kill cmos if the static was avoided .

The DMM I used is 20 Megs, and it still read like an open circuit at that setting.

I contacted the company and they said "You ordered a Anti -Static Pink form, not a conductive foam. " (sic)

Should I trust this stuff is indeed anti-static?

The black conductive foam I have measures between 1k and 10k at typical lead spacing (0.1 in). The pink stuff I have measures as an open circuit.

If you go back to that link I posted on the first page, Steve Conner gives some info about the different kinds. Probably enough key words to do some digging to see if the anti-static stuff will do what you want.

amptramp · February 17, 2012, 12:35:51 PM

The black anti-static foam has a finite high resistance that will discharge items at low current. The pink anti-static foam is only intended to not be a source of static charge. You can get static charge by shuffling your feet over a carpet, but not if your carpet was anti-static pink. But the pink foam does not discharge anything.
