What happens if you staple ESD Bags shut? Does that damage the ESD Bag’s effectiveness? What if the ESD Bag is heat sealed shut & a staple on the seam is used to attach paperwork?

Answer:

Desco Statshield® ESD Shielding Bags have a layer of metalized film which creates continuous conductive enclosure or Faraday Cage to provide electrostatic shielding protecting the ESD sensitive devices placed inside the Bag. The use of stapling to close ESD Bags is counter productive and not recommended. The metal staple provides a conductive path from the outside of the ESD Bag to the inside. The use of a metal staple would undermine the effectiveness of the ESD Bag making a conductive path for charges outside the Bag to charge outside the Bag to charge or discharge to ESD sensitive components inside the Bag.

To close the ESD Bag, it is recommended to heat seal, or use Desco ESD Labels after the opening of the bag has been folded over.

Carefully locating the staple to only the seam of the Desco Statshield® Bag would theoretically make it part of the “continuous conductive enclosure” and be acceptable. However, we are not aware of any end user using this method and cannot recommend it. The staple would be an exposed conductor that could charge or discharge to ESD sensitive devices.

So how many product failures are due to ESD damage? Nobody ever really knows, but we have been told that about 50% of non-physical damage product failures in particular industries are due to ESD events. This number seems to work for most electronics manufacturers that we work with. Thanks to Chip Overclock for taking the time to get us a little closer to knowing how many product failures are due to ESD damage.

How are the electronics inside plastic cell phones and hand held computers protected from externally generated electrostatic fields? -Anonymous, Elkhorn, Wisconsin

Answer:

The electronics inside plastic cell phones and hand held computers may be protected from externally generated electrostatic fields by several factors: 1 – a static electric field does not generally penetrate materials, especially Gaussian surfaces (housings, chassis, etc.) 2 – a working commercial electronic device must pass certain safety requirements 3 – the Input Output (I/O) connections are generally well protected on a finished electronic device 4 – the paths into the device might be more involved (high impedance) and slow the effect of an ESD event Some things you should watch out for: – Open and direct I/O ports where an ESD event could occur (leading the current pulse into the device to wreck havoc) – dynamic electric fields (when a static field collapses, due to say an ESD event) and where they discharge to – finished electronic devices are still susceptible to ESD events, especially when a metal surface is involved.
