Harsh Storage Environment Anti-Moisture Methodology
Requires Flash Player.
Humidity management in enclosures located in non-environmentally controlled areas is an important contributor to reliability of the electronic components. Moisture can cause reliability problems leading to product failures as the result of water adsorption or dew formation on the surface of PCBs, components and interconnects. Climatic testing of electronic products in climatic chambers is today a must for telecommunication, automotive and military applications exposed to severe climatic conditions. However there is a problem judging the formation of dew and invisible mono-layers of water on hard-to-access PCA surfaces. This presentation will describe an experimentally-supported CFD methodology for fitting an existing non-hermetic enclosure for storage in harsh climatic conditions (humid hot coastal desert environment).

Overview
This presentation describes an experimentally-supported CFD methodology for fitting an existing non-hermetic enclosure for storage in harsh climatic conditions (humid hot coastal desert environment).
Humidity management in enclosures located in non-environmentally controlled areas is an important contributor to reliability of the electronic components. Product failures can occur as the result of water absorption or dew formation on the surface of PCBs, components and interconnects. Climatic testing of electronic products in climatic chambers is a must for telecommunication, automotive and military applications exposed to severe climatic conditions. However there is a problem judging the formation of dew and invisible mono-layers of water on hard-to-access PCA surfaces. Determining the correct configuration and power budget for anti-moisture measures will also be illustrated.
