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

Answer: A

Correct answer: Placing an IC in a non-conductive plastic bag

An ordinary plastic bag is an insulator and generates charge as the component moves inside it - which is why antistatic bags are made conductive. A grounded mat and a touched chassis both drain charge away.
