Previous Technical Data columns have covered thermal properties for many of the materials that are common to electronics packaging. The Technical Data for this issue is broader in scope and addresses common building materials, some…read more
Providing More Value Than Playing Video Games
November 1st, 2007
ElectronicsCooling magazine was founded more than 12 years ago with a mission of providing current and practical thermal management information with archival value. I hope you agree this magazine is still delivering on its original…read more
Thermal Diffusivity
August 1st, 2007
Thermal diffusivity is a measure of the transient thermal response of a material to a change in temperature and the term thermal diffusivity (α) is defined as α = k/(ρ x cp) where α is…read more
Moisture permeation in electronics
May 1st, 2007
Environmental control for electronic packages and enclosures often involves understanding and managing moisture concentration. Excessive moisture combined with processing temperatures can cause damage. High humidity levels have other potentially harmful effects such as corrosion. Since…read more
