Accendo – Preventing Moisture and Corrosion Damage on Electronics in Harsh Conditions

October 20, 2020 @ 9:00 am – 10:00 am

By Dan Jenkins

The goal of this presentation is to educate the audience of options to prevent electronic equipment failure used in enclosed spaces from corrosion through preventative maintenance practices.    As most know, the metals used in today’s electronics are processed but want to turn back to its original state as the iron components will oxidize, and the corrosion process begins.  The addition of humidity, vibration, temperature swings and acid environments (such as being in a tire plant or downwind from a refinery) will accelerate the process.  It is this corrosion and subsequent weakening or disfiguring of the metal that causes malfunctions and failures. 

The presentation will discuss the following maintenance options along with their pros and cons.

1)The use of barriers in the form of coatings and films to protect the metal.  

2)The use and different types of desiccants to reduce moisture. This will include Silica Beads, Diatomaceous Earth, and Expanding Polymers.

Additionally, the presentation will review how humidity develops and what actually happens to it in enclosed spaces.  Finally, the presentation will review some simple self-test methods used to determine efficacy and a few related industry standards regarding protecting electrical components in storage.

This information will help engineers and managers make better-educated decisions to help prevent failure of electronic components that affect the facility’s reliability.
