I have an out-door cabinet (with PCB) that over time is being damaged due to condensation (humidity). I would like to minimize these damages over time (corrosion, etc...) The cabinet is closed but not 100% sealed. Cabinet size is 80X20X20cm. How do I avoid the damages due to condensation of air inside the cabinet? Changes I can implement are: 1. Changing the external geometry of the cabinet. What would be the preferable geometry? 2. I can change the coating of the internal components (cabinet included). Any recommendations?
