Clearing the static: Electrostatic packaging - Topic 6

28 August 2019 News

The purpose of electrostatic discharge (ESD) packaging is to protect ESD-sensitive objects from ESD damage; especially when items are being transported outside of the designated ESD protected area. ESD packets, boxes and containers safeguard objects from ESD in three key ways:

1) By preventing direct ESD impact on the item contained within.

2) By dissipating static charge from the package surface.

3) By providing a robust exterior for protection against physical impact, as well as dust and humidity.

Antistatic bags

ESD bags are ideal for small electronic components, such as PCBs. ESD bags can be categorised into antistatic (low charge), conductive, and shielded material. The resistivity standards governing your industry and application will determine the type of material to be used. Most bags consist of a polyethylene and polyester layer with a black, pink or metallised tint for identification.

Antistatic boxes

Cortronic boxes feature an impervious static dissipative skin and conductive core. It is classified as ESD shielding material suitable for use in ESD protected areas.Applications include component boxes, PCB transit boxes, IC tube boxes, and in-plant handlers for PCBs.

Conductive containers

Utz is the world leader in material-handling solutions. Utz offers an extensive range of static conductive containers, bins and trays for safe handling, transport and storage of ESD-sensitive components and assemblies.

Tip: ESD foam and moisture barriers, such as desiccants, should be used within packaging for added protection.
