SMD carrier uses anti-static materials: Metals are conductors, and because the leakage current of conductors is large, it can damage devices. Additionally, because insulating materials are prone to electrostatic discharge, they cannot be used as anti-static materials.
Instead, materials with surface resistances of less than 1×105Ω·cm, such as so-called electrostatic conductors, and materials with surface resistances of 1×105-1×108Ω·cm, such as electrostatic subconductors, are used as anti-static materials. For example, common electrostatic protection materials are achieved by mixing conductive carbon black into rubber, with the surface resistance controlled below 1×106Ω·cm.
