Thermal Interface Materials

The next post in our hot summer blog series, we are writing about Heat Spreaders.  Heat spreaders are thermal management solutions to be used in tight spaces where a traditional heat sink would not work. Heat spreaders utilize x-y thermal conductivity to move heat within a small space to a larger surface area, dissipating the heat in order to cool the device.  They are made of thin copper and aluminum sheets with conductive pressure sensitive adhesive laminated to one side. Their thin and flexible characteristics allow for 100% contact even on non-flat surfaces, optimizing thermal performance.

For a sample, quote or a prototype of your custom heat spreader component, contact a Marian Engineer.
