Thermal Resistivity and Thermal Conductivity in Silicone Foam and Sponge

Posted by Katie Sullivan

Jan 27, 2017 10:13:34 AM

Thermal resistivity and thermal conductivity can be two very important physical features of foam materials to certain applications. Most devices containing electronics must be designed to deal with heat in one way or another. Electronic circuitry operates most reliably at lower temperatures. High operating temperatures decrease the service life of the device or module.  It is critical for designs to either conduct or isolate heat.

What You Need to Know about the TR Series

Posted by Crystal Deel

Jun 22, 2016 11:01:30 AM

Nitto’s TR series is a must have for thermal and electronic applications. The TR series features a selection of double coated tapes including TR-5912F and TR-5925F. These tapes acquire powerful adhesion which accounts for its strength and reliability. Nitto recommends replacing the use of a screw in an LED or other thermal applications with these thermally conductive adhesives for the best performance. Using the tape method offers superior thermal conductivity performance, and can extend the life of your LED, compared to using the screw method.

Thermal Management in LED Light Assemblies

Posted by Katie Sullivan

Although LEDs are considerably more efficient than traditional lighting forms, they do still produce heat. This heat can have an adverse effect on the LED and therefore must be managed to ensure the true benefits of this technology are realized. If excessive junction temperatures are reached, particularly above the maximum operating temperature of the LED (~120-150˚C), a non-recoverable effect could occur, leading to complete failure. Operating temperature is a directly related to the lifetime of the LED; the higher the temperature, the shorter the LED life.

THIN HEAT SPREADERS: Hot Summer Blog Series - Thermal Interface Materials

Posted by Katie Sullivan

Sep 8, 2015 2:00:00 PM

As summer comes to an end, we bring you our final post in our Hot Summer Blog Series exploring Thermal Interface Materials. In this post we briefly look at heat spreaders.  A heat spreader is a heat exchanger that moves heat between a heat source and a secondary heat exchanger whose surface area and geometry are more favorable than the source.   Heat spreaders conduct heat in the x,y and z axes which spreads the heat to a larger surface area.

Thermal Gap Pads - HOT Summer Blog Series: Thermal Interface Materials

Posted by Katie Sullivan

Jun 3, 2015 2:14:42 PM

This is the kick-off to our Hot Summer Blog Series all about Thermal Management Materials.  

Why focus on Thermal management Materials?  Incredible technological advancements have been made over the past 30 years in electronic devices.  Just look at the image below.  

 

 

As devices have become smaller, thinner, and more powerful, the need for efficient removal of heat has become critical to the reliability and longevity of the device.  Heat is a normal by-product of electronics operation.  Thermal Management Materials exist to aid in the efficient conduction of heat within these devices to keep them running at a safe operating temperature.  There are many different types of Thermal Management Materials offering a range of conductivities, thicknesses and softness.  In this series, we will explore the different types, starting off with Thermal Gap Pads.

Thermal Pads vs. Thermal Grease

Posted by Katie Sullivan

Oct 8, 2014 2:00:00 PM

Thermal pads (also known as gap fillers and gap pads) are a preformed rectangle of solid material commonly used between a heat sink and a heat generating compound to transfer heat in an electronic assembly.  The advantages of thermal pads are that they are die-cut precisely to achieve a consistent part repetitively.  The electronics manufacturer knows exactly what they are going to get.  The solid thermal pads are easy to handle and install, leaving less room for assembly error.
