Hybrid product provides EMI mitigation while moving heat away from sensitive electronics

March 31, 2015 – Global technology leader Laird (LRD: London) today announces the launch of an innovative, dual-function, board level material that simultaneously improves signal integrity and temperature stability of electronic circuits.

Today as designers fight to fit more functionality into each circuit board, signal integrity is becoming more important than ever before. At the same time as devices become ever thinner, smaller, and more compact, space on circuit boards is difficult to come by.

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

CoolZorb 400 is a hybrid material that functions as both an absorber of Electromagnetic Interference (EMI) and a conductor of thermal energy. The product 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.

“As a result of the many new and emerging design pressures facing electronics manufacturers in such industries as IT/ Datacom, Wireless, Telecom Infrastruction and Smartphone/ Tablets, the application of thermal management strategies and EMI shielding has become more complex," explains Laird’s Senior Vice President of Performance Materials, Naoto Mizuta. "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 product 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.

CoolZorb 400 imparts thermal conductivity and EMI attenuation in the microwave frequency range with best performance at or above 5GHz. It also meets requirements of the UL94 V0 flammability standards. For more information, click .
