Air discharge test

The rounded ESD gun dedicated to air test is used. The voltage generator is set to the

desired level and the ESD gun moved with the slide arm towards the PCB probe tip until a

spark appears and then further until the ESD gun tip touches the PCB discharge tip. This

action is repeated ten times minimum, in positive and negative polarities.

Contact discharge test

The sharp tip ESD gun dedicated to contact test is used. Contact is maintained with the

PCB discharge tip by locking the slide arm. The generator is set to the desired voltage and

ten discharges minimum are applied in positive and negative polarities to the device under

test.
