System level improvements for a product in a plastic enclosure without exposed connectors to pass IEC 61000-4-2. Discharges through slit zapped LEDs

Our product failed ESD during precompliance. Specifically, 4 LEDs got zapped, six times each (3 positive and 3 negative charges), during an 8kV air-discharge test, causing permanent damage to the LEDs only, some are on for brief random moments but…

Does paint affect EMI ability of enclosure?

This could be a very stupid question, but when it comes to RF you never know. Does painting (non-conductive) over the top of a grounded metal enclosure affect its ability to absorb/block RF interference? At the mechanical fixings, the enclosure is…
