Page 9: Machine Handler For Programming
Friction between the cylinder and the rod generates the charges and induces on the test probe. To minimize the ESD, a grounding path is jointed from the conductive part in the handler to metal framework which is then jointed to the earth. - Page 10 The Prevention and Control of Electrostatic Discharge (ESD) AppNote082 Rev1.1 Machine metal framework (conductive) Hydraulic cylinder Programming pins Connect to ground Dragonchip 10 of 13 DragonFLASH We bring silicon to life...
- Page 11 The Prevention and Control of Electrostatic Discharge (ESD) AppNote082 Rev1.1 Grounding example: Conductive part Joint a wire to the ground If the reading of resistance measurement keeps changing between conductive materials while static or moving, it is an indication that the contact is not stable, and a new grounding path should be installed.
