I have to design a electronics device that is specified for environmental operating conditions of 0°C to 60°C with 5% to 95% relative humidity (non condensing).
I think the temperature part should be covered with commercial component selection (0°-70° operating temp.), but what about the humidity requirement?
- Is this humidity specification hard to achieve?
- Do I need to protect the PCBA with conformal coating?
- What are the general recommendations for different humidity specifications?
Of course I will need to perform some tests in the climate chamber. But I think there should exist some general guidelines for the design regarding humidity?
