Sensitive electronic components in antistatic ESD packaging.
Electrostatic discharge (ESD) occurs when a sudden flow of electricity happens between two objects with different electrical potentials, typically caused by direct contact or an electrostatic field. In electrical devices, ESD can happen during manufacturing, handling, or operation. When accumulated static electricity discharges, it can damage sensitive components, such as integrated circuits (ICs), transistors, and memory chips. ESD events can lead to latent defects, reduced reliability, and even catastrophic failures.

Protective measures to mitigate ESD risks include incorporating materials like conductive plastics to safely dissipate static charges. Conductive plastics are engineered by incorporating carbon black into various polymer matrices, such as PP, PE, PS, ABS, and others. This addition of carbon black enhances the conductivity of the plastics, transforming them from insulative materials to effective ESD protectors. These materials are lightweight, corrosion-free, and easier to produce than metal-based alternatives, making them a cost-effective solution for ESD protection.
These materials create a network within the polymer that allows electrons to move freely, providing the necessary pathway for electrical conductivity. Their ability to combine the mechanical properties and processing advantages of plastics with electrical conductivity makes them valuable in industries like electronics, automotive, and aerospace.
The use of conductive plastics extends across numerous practical applications. Companies such as Premix have developed electrically conductive and static dissipative plastic compounds designed to reduce the extent of hidden failures and guarantee a longer operation life for electronic devices. Some of their portfolio include:

1. Material: PET transparent (antistatic) Film of Thickness=1.05mm±0.05mm,
2. Point-to-point resistance value: 1.0*10^4 2-1.0*10^9 Ω
3. Ground resistance: 1.0*10^4 2-1.0*10^11Ω
4. Electrostatic value: ±100V
5. Tray incoming material should not be damaged, broken, dust, oil
6. Tray shall meet ROHS standards at the factory
Customers, need value as per the above specification in film with inheritance additive added for antistatic not with coating as they need a shelf life of more than 6 months which they are getting in the current film. Can you please guide/suggest the way forward with – a) What suitable additive to achieve the result 1.0*10^4 2-1.0*10^9 Ω – can you please share supplier contact details? b) Source details of economical test equipment to check point-to-point resistance?
Pls. suggest/guide Best Regards Prashant
