Enclosure Design

IN SPE research on the effect of enclosure design on electronic reliability focuses on parameters such as openings, barriers, convention and humidity flow.

Enclosures for electronic devices have the functionality of protecting people and animals from touching the electronics, to protect the electronics from mechanical and environmental impact and finally, the enclosure provides a design/ user functionality interface. 

In the IN SPE project, typical devices with enclosures are selected and evaluated in detail and thorough lab testing is conducted. Field performance data and failures are analyzed in detail and the knowledge obtained is used to generate a matrix with the strengths and weaknesses. The work also includes a detailed technology survey and bench marking of available methods for regulating humidity and possibility of integrating them to typical enclosures.
