Salt Fog: A Raspberry Pi’s Worst Nightmare

Salt fog testing is one of the most aggressive tests for evaluating a device’s resistance to corrosion. The test is conducted in a sealed chamber where a sample PCB or device is introduced to an extremely corrosive sodium chloride rich fog atmosphere. This contained and highly amplified corrosion acceleration model creates a scenario that allows HZO’s technical team to predict the reliability of coatings in extreme as well as real world conditions.

In these tests, the samples are exposed to an atmosphere of 95 degrees Fahrenheit, and 100% humidity. To put that in perspective the most humid place on earth is Cherrapunji, India which can reach up to 95% humidity (in the middle of summer). So if 100% humidity isn’t a realistic expectation, that begs the question, why do it?  Simply put, we do it to push our technology to the limit.

The results speak for themselves:
