ESD Tray

A company that develops itself into a global one based on
continued research and introduction of new technology

What is ESD Tray?

Electrostatic discharge +This is the tray optimized for the prevention of infection by alien substances(dust and etc.), and SUNGGOK's ESD tray is categorized into the following three according to the surface resistivity (Ω) in accordance with the US Military Standard.

Anti-static tray

  • Surface resistivity(Ω/cm)

    1010 ≤ Rs ≤ 1011 Ω/Sq

  • Electrification

    Attenuate immediately after charging with electricity

  • Application field

    Anti-static

Static Dissipative tray

  • Surface resistivity(Ω/cm)

    106 ≤ Rs ≤ 109 Ω/Sq

  • Electrification

    Barely charge with electricity

  • Application field

    Anti-static / Prevent power storage

Conductive tray

  • Surface resistivity(Ω/cm)

    Rs ≤ 10z5 Ω/Sq

  • Electrification

    No charge with electricity at all

  • Application field

    Electromagnetic shield
