Part 1 can be found here. Part 1 of this article provided the groundwork for the present discussion [1]. It demonstrated the use of three different methodologies for performing a transient thermal analysis of a high-power IC package attached to a heat sink. These include the finite element analysis (FEA) method and a numerical model, which represents the package and heat sink … [Read more...]
Thermal Facts & Fairy Tales: Heat Spreading Revisited
AS PROMISED IN MY editorial of the 2011 Fall issue, I will devote this issue’s column on the topic of heat spreading. The reason is that I, while writing a white paper on basic thermal management for LED applications, found some unexpected facts pointing at problems of interpretation of heat spreading data for dual layers when using the often-used heat spreading equations. In … [Read more...]
Bottlenecks and Interface Materials; Part 3 – Relieving Thermal Bottlenecks Reduce Temperatures
As with all good inventions, you quickly wonder how on earth you could have done without them before. Relieving thermal bottlenecks reduce temperatures; it’s so blindingly obvious. Now that we have the ability to visualise with FloTHERM exactly where the thermal bottlenecks are in a design, the job of the (overworked/underpaid) thermal design engineer just got that more … [Read more...]
Bottlenecks and Interface Materials; Part 2 – When TIMs Go Bad
‘Bits stuck onto other bits’, a succinct definition of an electronic product, if not a product that contains electronics. Soldering is the method of choice for getting the components to attach to the pcb, the layered board that contains the metallic traces connecting component pins to other component pins. Rivets, welds, screws or bolts for the chassis, some form of … [Read more...]
Has Your Brand Image Been Hijacked?
Electronics Cooling Business Bulletin Volume 6 | January 2012 In a recent article entitled “Who is Managing Your Brand Image?” my colleague, Graham Kilshaw, explained how customer behavior has effected a significant shift in marketing, from direct response advertising to brand advertising. As customers gather on social sites where they share opinions and, in turn, are … [Read more...]
