• What does ESD mean?
ESD stands for Electrostatic Discharge.
• What does it mean if something is classed as an EPA?
EPA stands for ESD Protected Area. This is a defined space within which all surfaces, objects and people need to adhere to the IEC guidelines to eradicate the possibility of an electrostatic discharge. An EPA can be an area such as a single table or a complete production.
• What is the difference between dissipative and conductive properties?
ESD protection products have different electrical conductivity characteristics classified as dissipative (surface resistance range >1x104 Ω - <1x1011Ω) or conductive (<1x104 Ω). Once the material is classed as insulative then there are greater chances of the material charging and in turn leading to an electrostatic discharge.
• What is the difference between dissipative and a shielding packaging?
Shielding packaging (bag, carton, box, etc.) has a shielding layer in the construction, often a metal layer, which prevents electrostatic discharges from penetrating the packaging and therefore protects the sensitive electronics. All sensitive electronics (ESDS Electrostatic Sensitive Device) must be stored and transported in a shielding packaging once transported outside the EPA.
Dissipative packaging is primarily intended for mechanics / non-ESD sensitive materials and components which are transported into an EPA. The dissipative material will not create a charge but is not guaranteed to protect the ESDS from a discharge. Dissipative bags can also act as dust protection for ESD sensitive products and materials within an EPA.
• How to best store ESD-protected material to extend its shelf life and maintain product quality?
Most dissipative plastic bags have a shelf life since the active substances used in production to obtain the ESD properties deteriorates and degrades over time. Most of the products / materials have a guaranteed shelf life of approximately 12 months. We have also dissipative materials with a 3-year function guarantee and even permanent properties. Common to most dissipative materials is that the properties are affected by UV light - therefore storing the materials away from UV light or in closed boxes will maintain the dissipative properties.
Please note that dissipative tote boxes will not lose their dissipative properties over time.
• Can you order customized products (bags, matting, foam, boxes etc.) and solutions according to customer requirements?
Absolutely, we can adapt and cut both table and floor matting, shielding boxes and foam in the desired dimensions and specifications. We can also create specific dissipative and shielding bags and covers with or without unique printing. We also have great opportunities and flexibility to develop customized products for internal and external transport. Feel free to contact us with your questions or needs and we will do everything we can to help.
