Elektrostatic Discharge - ESD



Electrostatic discharge

During the transport or filling of load-carriers such as plastic bins and pallets, static electricity arises due to friction. This must be conducted away immediately, otherwise electrostatic charging takes place. This charging up is likely to be followed by an electrostatic discharge (ESD). Such a discharge may cause serious damage, if it is not dealt with correctly. Electronic components used in the electronics industry, such as semiconductors and ICs, are very sensitive to electrostatic charge and its subsequent discharge. Defects caused in this type of product by ESD may lead to great expenses for the manufacturer. Repair costs, damage compensation or the loss of customers may result. It is therefore of great importance to deal correctly with the dangers of ESD. Various precautions are possible to ensure that ESD has no chance in your business.

Using Transoplast’s ESD range, you are always assured of safe transport and storage of your electrostatic-sensitive products.




ESD


If a product does not charge up, no discharge happens either.

The above maxim is one of the most important principles when handling electrostatic-sensitive products. All plastic products in Transoplast’s ESD range dissipate electrostatic charge through the addition of a carbon compound. This means that the electrostatic charge can flow away relatively quickly. The load carriers’ dissipative material thus prevents the contents charging up. Our plastic products’ dissipative characteristics thus ensure adequate protection of electrostatic-sensitive products. However, a storage system only provides protection against the dangers of charging up and discharging (ESD) when the entire system consists of electrostatically dissipative materials. For this reason, in addition to plastic bins Transoplast supplies wheeled chassis and plastic pallets in ESD versions. This way, earthing happens in a responsible way and electrostatic charge can flow away relatively quickly.


Surface resistance

In order to combat product damage by ESD, it is important that static electricity is conducted away as quickly as possible. The definitive parameter for the conduction of electrostatic charge is the surface resistance. The specific surface resistance is measured according to DIN 53428 and IEC 60093. The surface resistance of the products in our ESD range lies as standard between 104 and 1010 ohms (unless otherwise indicated). The material is thus characterised as dissipative. Voltage differences are in this way neutralised in a relatively short time. Products with a surface resistance lower than 104 ohms (electrostatically conductive material) are available on request.
