Evaluate Heat Sink Contact Pressure

Background

High density, active, electronics emit energy that can raise their temperature leading to failures. Heat sinks are secured to components to dissipate their heat.

Challenge

For the heat sink to function properly, even contact must be achieved between the part being cooled and the heat source. This can be difficult to achieve due to the mechanically “stiff” nature of the heat sink and hard surfaces involved; where contact may be achieved well at one or two points, larger regions of potential contact have gaps.

Solution

The I-Scan™ pressure mapping system uses patented, paper-thin sensors that can easily be inserted between these two mating surfaces to evaluate and improve the contact. With the help of Tekscan’s highly qualified sales and engineering support team, each system may be configured to meet your specific needs.
