Early Detection of Environmental Conditions That Will Lead to Creep Corrosion on Printed Circuit Boards in Data Centers

11) A method to monitor creep corrosion propensity of the air comprising:

• providing a printed circuit board with inter-digitated comb patterns having spacing in between the patterns, the circuit board connected to a microprocessor;
• connecting, in series, a power supply and a high resistance resistor to the printed circuit board
• connecting at least one of a data logger and an alarm circuit to the microprocessor to create a corrosion monitor;
• monitoring, by the microprocessor, the resistance of the circuit as voltage passes through the circuit;
• writing data to the data logger and triggering the alarm circuit in response to the voltage exceeding a threshold value.
