Page 5: Preventing Esd Damage
Preventing ESD Damage ESD damage cannot occur if there is no voltage difference between the components and any object that touches them. That is how anti-static packaging works. Anti-static bags allow the static charge to flow over their surface, so that any part of the bag that touches the components inside are all at the same potential at all times. Anti- static foam keeps the leads of sensitive components at the same potential. -
