Board level material solves thermal & EMI issues in circuits

The CoolZorb 400 provides designers with much needed flexibility by improving signal integrity and temperature stability all from a single solution. This material can increase the speed of the design cycle, simplify manufacturing processes and create material cost savings.

The CoolZorb 400 is a hybrid material that functions as both an absorber of EMI and a conductor of thermal energy. The material is used like traditional thermal interface material where it is placed between the heat source, such as an IC, and heat sink or other heat transfer device or metal chassis. The silicone-based material can simultaneously protect electronics from both EMI and heat, thereby saving design engineers both space and money.

The CoolZorb 400 imparts thermal conductivity and EMI attenuation in the microwave frequency range with best performance at or above 5GHz. The material also meets requirements of the UL94 V0 flammability standards.

“As a result of the many new and emerging design pressures facing electronics manufacturers, the application of thermal management strategies and EMI shielding has become more complex," said Naoto Mizuta, Senior Vice President, Performance Materials, Laird. "The use of hybrid solutions such as the CoolZorb 400 to solve both thermal and EMI issue is set to grow drastically over the coming years."

The CoolZorb 400 is available in sheet stock (12” by 12” size) and as cut parts to customer specifications. Standard sheet thicknesses are .020”, .040”, and .100” but other thicknesses can be made to order.
