A technician is unpacking a new expansion card and notices it arrived inside a metallic-looking bag. What is the primary purpose of this type of packaging?
- ATo make the card waterproof during transport
- BTo keep the card sterile for medical environments
- CTo prevent electrostatic discharge from damaging the components
- DTo block electromagnetic interference during shipping only
Show answer & explanationAnswer & explanation
Correct answer: C. To prevent electrostatic discharge from damaging the components
Anti-static (static-shielding) bags are conductive or dissipative bags designed to protect sensitive electronic components from electrostatic discharge (ESD) during storage and shipping. They are a core part of ESD prevention alongside wrist straps and mats.
Why the other options are wrong
- A. These bags are not designed as waterproofing.
- B. Sterility is unrelated to electronics packaging.
- D. EMI blocking is not the primary design purpose of these bags.
Static-Shielding Bag
A conductive bag used to store and transport electronic components to protect them from electrostatic discharge.
- Often has a metallic silver or pink anti-static tint
- Used alongside ESD mats and wrist straps
- Should be used when storing spare parts, not just during shipping
Memory trick: Silver bag, safe chip.
