receive at least 50 direct contact
discharges.
If no direct contact test points are available, then at least 200 indirect discharges
shall be applied in the indirect mode. Test shall be performed at a maximum
repetition rate of one discharge per second.
The selected point, which was performed with electrostatic discharge, please
refers to the “Photo(s) shown the location(s) of ESD evaluated”.
Vertical Coupling Plane (VCP):
The coupling plane, of dimensions 0.5m x 0.5m, is placed parallel to, and
positioned at a distance 0.1m from, the EUT, with the Discharge Electrode
touching the coupling plane.
The four faces of the EUT will be performed with electrostatic discharge.
Horizontal Coupling Plane (HCP):
The coupling plane is placed under to the EUT. The generator shall be positioned
vertically at a distance of 0.1m from the EUT, with the Discharge Electrode
touching the coupling plane. The four faces of the EUT will be performed with
electrostatic discharge.
If no direct contact test points are available, then at least 200 indirect discharges
shall be applied in the indirect mode. Test shall be performed at a maximum
repetition rate of one discharge per second.
