Laird Technologies Introduces Thermally Enhanced Board Level Shielding Solution for Heat Removal.RoHS Compliant Convergence Technology Combines EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. Shielding and Thermal Management Into a Single-Assembly Solution ST. LOUIS -- Laird Technologies, a leading designer and manufacturer of antenna, electromagnetic interference See EMI. (EMI) shielding, telematics Originally coined to mean the convergence of telecommunications and information processing, the term later evolved to refer to automation in automobiles. GPS navigation, integrated hands-free cellphones, wireless communications and automatic driving assistance systems all come under the and thermal management solutions, introduced today its Thermally Enhanced Board Level Shielding technology (T-BLS), a RoHS compliant cooling method for electronic devices where board level shielding is required. T-BLS is a single-assembly solution resulting from convergence technology which combines two different technologies into one product. Convergence technology provides many benefits to Laird Technologies customers because it can reduce component and part count, save space in an application and ultimately, reduce costs. Laird Technologies, and industry leader in both EMI shielding and thermal management, is one of the few companies to combine technologies, and its new T-BLS product is the second in a series of converged products. "Advanced cooling techniques become increasingly important as more powerful components and increased package densities are added to applications. Our unique approach to combining thermal interface materials A Thermal Interface Material (aka TIM) is used to fill the gaps between thermal transfer surfaces, such as between microprocessors and heatsinks, in order to increase thermal transfer efficiency. These gaps are normally filled with air which is a very poor conductor. with board level shielding produces more reliable electronic products such as PDAs, cellular phones and portable DVD players A handheld device with a built-in DVD drive and flip-over lid that contains a screen, typically 6" to 10" in size. It may support rear seat passenger viewing, in which case the unit is hung upside down from the back of the front seat head rest, and a switch flips screen content 180 ," said Steve Ulm global product director, Laird Technologies. "By combining EMI protection and thermal management, Laird Technologies and our strategic business units provide customers with a state-of-the-art option for their board level shielding and thermal requirements." The T-BLS system uses Laird Technologies' T-flex[TM] 600 Series thermal gap filler Gap fillers, as used on the New York City Subway, are movable platform extensions used in certain stations where the curvature of the platform creates a significant gap between the platform and subway car door. In contrast, see "Mind the gap". , a soft, extremely compressible com·press·i·ble adj. That can be compressed: compressible packing materials; a compressible box. com·press material with high thermal conductivity thermal conductivity A measure of the ability of a material to transfer heat. Given two surfaces on either side of the material with a temperature difference between them, the thermal conductivity is the heat energy transferred per unit time and per unit . Its function between the electronic component and board level shield helps to remove heat from the component by eliminating air gaps and reducing the overall thermal load; therefore, extending the life of the product. T-BLS technology is available in custom designs with various shapes and thermal interface materials. Pricing for a one-by-one inch square board level shield with a T-flex 600 Series thermal gap filler is $0.40 for high-volume applications in excess of 100,000 parts. Smaller quantities are generally priced at $0.75 each. Pricing is dependent upon application requirements. About Laird Technologies Laird Technologies is the world's leading designer and manufacturer of antennas, electromagnetic interference (EMI) shielding, telematics and thermal management solutions for the telecommunications, data communications data communications, application of telecommunications technology to the problem of transmitting data, especially to, from, or between computers. In popular usage, it is said that data communications make it possible for one computer to "talk" with another. , computer, general electronics, network equipment, aerospace, defense, automotive and medical equipment industries.
