ABSTRACT
Electronic equipment has made its way in to practically every aspect of modern life, from toys to high power computer. Electronic components depend on the passage of electric current and they become potential sites for excessive heating since the current flow through a resistance is accompanied by heat generation. Continued miniaturization of electronic system has resulted in a dramatic increase in the heat generated per unit volume. Unless properly designed and controlled; high rates heat generation result in high operating temperatures for electronic equipment, which jeopardizes its safety and reliability.
