EMC screws are used in the Bonding/Riveting repair method to reestablish bonding transition.
They assume the function of welded joints, which ensure transition to ground between the individual components.
The punch or blind rivets used in the repair do not guarantee permanent bonding transition between the individual components!
The EMC screws ensure the operational reliability and safety of the electrical/electronic components following repairs!
