Q1:

ESD damage can be caused by:

A Placing an IC in a non-conductive plastic bag

B Placing an IC on a grounded mat

C Repeated sags in current supplied from outlets

D Touching metal on the chasis

E None of the above

ANS:A - Placing an IC in a non-conductive plastic bag

Conductive Foam: Conductive foam is a polyethylene foam filled with carbon (as are all black ESD foams) , giving it its conductive properties and color. Conductive foam is designed for repeat use, and will act like a Faraday cage when an item is fully enclosed within it. Because of this a silver conductive bag is not needed as an outer container when using conductive foam.
