| Packaging | What it does | Typical use |
|---|---|---|
| Static shielding bag | Surrounds the part with a shield, so outside charge does not reach it. Also limits charge build-up. | Boards, modules and sensitive parts in transit and storage |
| Dissipative bag | Lets charge drain away slowly and resists charge build-up. | Handling inside the protected area |
| Conductive container or tray | Gives a conductive path around parts. | IC trays, tote boxes, component storage |
| Moisture barrier bag (MBB) | Blocks moisture and usually has static shielding as well. | Moisture-sensitive devices that need dry storage |
How to choose
- Where will it go? Inside the area only, or out on the road?
- How sensitive is the part? If unsure, use shielding.
- Is it moisture sensitive? Then you need a moisture barrier bag, desiccant and a humidity indicator card.
- Size and closure. Zip-top, heat-sealed or open-top; measure the largest item.
Moisture-sensitive parts
Parts rated for moisture sensitivity are packed dry and sealed. Handling and floor-life rules are set in JEDEC J-STD-033. Use the packing method the part maker specifies.
Do not reuse a damaged bag. Check the bag marking and your own programme for the requirements that apply.
