The term “thermal materials” represents a vastly broad category of electronic packaging constituents. They are the metals, ceramics, alloys, laminates, composites, organic and inorganic materials, as well as plastic compounds that are designed to play a crucial role in managing thermal energy and device level stress in today’s modern electronic packaging.
Now that we have defined what thermal management materials are, why should you care? Simply put, because they are the foundation of system reliability.
There’s a good reason for the development of every one of these materials, and at the crux of it all is the integrated circuit (IC) itself. Simply stated, all integrated circuits generate heat as a by-product of their operation. If not efficiently managed, the heat in the product or system that contains the IC can act to shorten the lifespan of that product or system.
Nearly every engineer or product designer responsible for building robust and reliable electronic products is compelled to pay close attention to managing the thermal by-product of device level temperature and the resultant stress that it places on the reliability of the IC. Building an electronic package improperly is like constructing a house with straw instead of blocks. If the foundation is weak and can’t effectively manage the environmental factors of wind, rain, summer heat, or winter cold, the house collapses. Similarly, if you build an IC on a poor foundation, it will not stand up to the stresses of operation. So it is for good reason that electronics design engineers are compelled to stack the right thermal management components to create a strong foundation for the integrated circuit.
Ready to start construction on your electronic package? Here are a few questions about issues related to thermal management technology to ask yourself first.
How do you need or want to mount the IC to the package foundation? Can the “cement” take up some of the stresses? Can the cement help dissipate the heat?
We know that these are all tough questions for package engineers to take into account.
