Dust accumulation in electrical devices becomes problematic when it impedes airflow, traps heat, or forms conductive paths on energized components. Initially, light dust layers are harmless, but compacted or moisture-laden dust can alter electrical behavior, leading to gradual overheating, instability, or eventual failure. Critical areas affected include cooling fans, heat sinks, and high-voltage zones on PCBs, where dust can degrade performance and accelerate component wear. AI
