There have been several studies that attempt to quantify the cost of corrosion. In 2002, NACE International came out with a study that estimated that corrosion was costing the US 276 billion dollars per year. The industries where corrosion had the biggest impact was
In terms of impact, electronics was merely a blip on the radar screen. Does the fact that corrosion cost estimates are so low for electronics compared with other industries mean that electronics are not susceptible to corrosion, or that electronics have better designs that inhibit corrosion? The answer is no: electronic components are highly susceptible to corrosion. Materials such as copper, tin, aluminum and silver all are susceptible to corrosion. It takes very little corrosion to impact some of the micro-miniature devices that are used in electronic applications. So why wouldn’t electronics be one of the major industries impacted by corrosion?
The following are some possible reasons:
What is the best technology for protecting electronic devices from corrosion? The answer is VpCI. VpCI is vapor phase corrosion inhibitor and it is the best way to protect delicate electronics. Many coatings or wraps are difficult to apply, and may actually degrade the electronic components that they are trying to protect.
How does VpCI work?
VpCI is vapor phase corrosion inhibitor made by Cortec, the process works as follows: VpCI molecules disperse into air by vapor pressure. As the molecules saturate an area, they come into contact with metal surfaces where the molecules break down and ionically bond to the metal. The bond forms a corrosion resistant surface; it does not alter the metal or effect the flow of electrons in anyway. Because the VpCI molecules disperse freely into the air, virtually every metal area in the vicinity will come into contact with the molecules. With VpCI there is no need for labor intensive coating or subsequent cleaning.
VpCI comes in a variety of Cortec products used for electronics:
Emitters: 105/111 Emitters are devices that can be attached inside a control panel or case and continuously dispense VpCI into the air. They protect up to 5 or 11 cubic feet respectively.
Cortec products can be used to protect electronic devices during the fabrication phase, shipping phase and during field use or extended storage. For more information on Cortec protection for electronics products, please contact Packnet or view the corrosion section of our website.
