Thermal Interface Solutions As an industry leader in high-performance, cost-effective Thermal Interface Materials (TIMs) and technologies, Laird designs and manufactures thermal products; including gap fillers and putties, phase change materials, thermal grease, and thermally-conductive insulator materials that meet the demands of any application. Meeting Ever-Increasing Thermal Demands Today’s electronics are smaller and more powerful than ever before, leading to ever increasing thermal challenges for the systems designer. While fans, heat sinks, and even liquid cooling and thermoelectric devices can be used to provide enough cooling power, the problem remains transferring the heat from the hot components into the cooling hardware. TIMs are designed to fill in air gaps and microscopic irregularities, resulting in dramatically lower thermal resistance and thus better cooling. Laird is the world leader in material development for TIMs and offers the broadest line of products to meet every design challenge. With gap filler pads, dispensable gap fillers, electrically insulating and electrically conductive pads, Laird’s thermal interface products can solve any TIM design challenge. In addition, Laird provides phase change TIMs that soften and fill tiny gaps at operating temperature, as well as thermally conductive greases that conform to any surface irregularity. Laird’s thermal interface materials offer operating temperatures up to 200°C, thermal conductivities over 8 W/mK in the Z axis, and tremendous flexibility in form factor and packaging to support any manufacturing scenario. Thermal Interface Materials Gap Fillers (TflexTM, TpliTM, TputtyTM) Laird gap fillers are used to bridge the interface between hot components and a chassis or heat sink assembly to increase the overall heat transfer from the system. The unique combination of thermal conductivity and softness reduces mechanical stress while maintaining thermal performance. Laird’s extensive gap filler product lines includes a wide range of performance capabilities, including ultrathin gap fillers, a high deflection series, and materials that provide electrical isolation. APPLICATIONS 10.0 100 8.0 80 6.0 60 • Telecom – wireless infrastructure, routers, and VOIP phones 4.0 40 2.0 20 • IT – notebooks, servers, memory modules, hard disk drives, solid state drives, scanners, and printers 0.0 0 • Consumer – gaming systems, LCD PDP televisions, and displays • Industrial – LED lighting, power supplies, lighting ballasts, controllers, scanners, and power converters • Aerospace and military – power supplies, microwave radio, and controllers Thermal Conductivity (W/mK) Hardness (Shore 00) Dispensable Gap Fillers (TflexTM and TputtyTM) Laird dispensable gap fillers are used to bridge the interface between hot components and a chassis or heat sink assembly when elimination of mechanical stress or bulk automated dispensing are critical design considerations. These materials can be dispensed to fill large and uneven gaps in assemblies and due to their super compliant nature; little to no pressure is transferred between interfaces. Laird’s dispensing product portfolio includes both one and two-part materials, as well as products specifically designed for vertical stability and consistent dispensing.

The Tpcm phase change product line is used in applications where reliability, repeatability, and handling must be controlled to optimize the performance as part of the total thermal solution. The Tpcm product line is available in a screen printable formulation that offers the reliability and performance of a phase change material with the low-cost handling of thermal grease. Tgrease is used in applications where a minimum bond line,constant pressure, and ease of screen printing are desired for optimal performance. Laird’s high-performance Tgrease products are designed to maximize reliability by eliminating pump out in most applications. APPLICATIONS • IT – servers, desktops, notebooks, and memory modules • Industrial – power supplies, lighting, LED lighting, and industrial electronics • Telecom – routers and wireless infrastructure • Consumer – gaming systems and portable devices Electrical Insulators (TgardTM) Tgard thermally conductive electrical insulators are used where electrical isolation is a critical design consideration, along with reliability, cut-through resistance, and thermal conductivity. The Tgard product line has a wide variety of materials for the unique performance, handling, and assembly considerations required in electronics devices. APPLICATIONS • Switching mode power supplies for: • Power semiconductors • Computers • Consumer electronics • Industrial • Audio and video components • Instrumentation • Automotive control units • Medical • Power conversion equipment • Electrical power generators • UPS Unit 3 | THERMAL INTERFACE SOLUTIONS 3 | THERMAL INTERFACE SOLUTIONS 4 | THERMAL INTERFACE SOLUTIONS Thermally Conductive Printed Circuit Board (TlamTM and TpregTM) Tlam thermally conductive circuit boards are designed with Laird’s unique dielectric materials 1KA and HTD. Tlam technology improves thermal performance while retaining good dielectric isolation. The 1KA material offers high thermal conductivity for applications where a thick dielectric is required. The 1KA material is available as a freestanding Tpreg to facilitate multilayer and FR4 hybrid circuit boards. The HTD material is used where high withstand voltage (>5000 V DC) and continuous use temperature of 150°C are required.
