ESD-Dissipative Mat Kit - Heat Resistant 2-Layer Natural Rubber Workbench Mat with Wrist Strap & Grounding Cable (3ft x 6ft, Light Gray) - Perfect for Electronics Repair, PC Building, and Anti-Static Workstations

The top layer is dissipative and the bottom layer is conductive. Resistively of Surface Layer (10 7~10 9 ohms) Resistivity of Bottom Layer (10 3~10 5 ohms, rattler loss <0.02g/cm2) Time for Static Dissipation (<0.5S) Heat Resistance (600oF, 10 sec no smell, no melt) What is ESD? Static, formally referred to as electrostatic charge, arises from excess of electrons on one surface and a deficiency on the other. The imbalance of electrons thus causes an electrical field that is capable of influencing other objects at a distance. The charge will remain in place unless it has a path through which it can flow. It may remain in place for some time and this gives rise to the term "static electricity". The word static simply means the charge cannot be equalized or transferred through electromotive force until there is a decrease in the capacitance between two objects. Protection against ESD is required during production, storage, and shipping stages of sensitive electronic components. ESD can damage or cause defects in electronic products, electronic component such as Surface Mount Device components and failure in Printed Circuit Boards. ESD-Safety and protection is required across a broad range of industries including electronics, automotive, biotech and pharmaceutical, medical devices, and semiconductors. Damage from ESD during mobile phone repairing is very common.
