Adequate cooling has long been a major concern for both manufacturers and users of electronic prod- ucts. Many of the benefits associated with improved reliability, increased power capability, and physical miniaturization can be traced directly to improved thermal cooling designs which have allowed device temperatures to be stabilized at a desired level despite variations in ambient conditions or the presence of a hostile operating environment. Increased device power dissipation along with smaller integrated circuits, packages, and printed circuit boards (pcb), require the cost effective and innovative application of heat sinks which are simple in design, light in weight, and utilize less space. In many electronic systems the problem of passively cooling high power devices has been dealt with through the utilization of "package level" heat sinks. Unfortunately, these types of heat sinks connect to only one package and have a limited surface area, and thus a finite cooling ability, while dramatically increasing the height or profile of the printed circuit board as shown in Figure 1.
