Cyclic vs steady-state damp heat: the quiet killer of PCBA and connectors
The real damage from damp heat is not "getting wet" but the insulation drop, electrochemical migration and corrosion triggered by a condensed water film. Cyclic damp heat is stricter than steady-state damp heat.
What an on-board charger has to be tested for: EMC, temperature rise, insulation and mating durability
OBC testing runs on four lines: EMC, electrical safety (temperature rise and insulation), interface durability (mating cycles and salt spray), and environmental protection (IP and vibration). EMC is the one to explore first during development.
