Page 71: Esd Guidelines
ESD guidelines Electrostatic sensitive devices (ESD) Electrostatic sensitive devices are destroyed by voltage and energy levels far below the limits of human perception. Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not electrostatically discharged. Electrostatic sensitive devices which have been subject to such voltages are usually not immediately recognized as being defective, because a malfunction does not occur until after an extended period of operation. - Page 72 ESD guidelines A.1 Electrostatic sensitive devices (ESD) ESD workstation The diagrams below illustrate the required ESD protective measures for electrostatic sensitive devices. ① ESD seat ② ESD standing position ③ ESD seat and ESD standing position Protective measures Conductive floor ESD table ESD footwear ESD smock...
