Due to the increased use of complex electronics, EMC shielding has become more important for the automotive industry. This development was confirmed by the active interest in our Laird Technologies booth at the annual congress „Zulieferer Innovativ 2005“at the Audi-Forum in Ingolstadt, Germany. In addition Laird Technologies presented its latest solutions for Thermal Management, which also poses a major challenge for automotive electronics. Find out more.

  
 

Thermal Management Products

With the acquisition of Orcus last fall, Warth this past winter and finally Thermagon this spring, Laird Technologies has become a force in the thermal management market.

Thermagon, since being launched in 1992, has lead the way in the thermal gap filler pad market growing to be the global leader for computer systems, power converters, telecommunications hardware, and automotive electronics. Orcus pioneered phase change thermal management materials since its inception in the mid 80’s. 

Warth based in the UK has had a strong position in Europe selling its thermally conductive insulators and accessories into many power conversion applications.  With this combination, Laird Technologies has expanded to offer one of the broadest lines of thermally conductive products over a wide range of industries worldwide.

Most of the thermal interface materials are supplied as sheets ranging in thickness from 0.003 to 0.200 inches.  Our thickness and dimensional configurations are custom designed to meet each customer’s needs. 

To address the demanding thermal needs of the most sophisticated devices in electronics, phase change material (T-pcm) or thermal grease (T-grease) is recommended.  These products provide thin bondlines and good surface wetting to produce the lowest thermal resistances.  They are generally 0.005 inches thick or less and used between a single device and a heatsink.

On the other hand, gap fillers find use in most market segments and are usually 0.020 inches or greater in thickness and vary in their thermal conductivity, softness, compressibility, and ease of use.  The Thermagon market performance leader is T-pli, the highest thermal conductivity polymer-based interface pad available.  Other product families include T-flex and T-putty.

For applications which require high dielectric strength such as power transistors Laird offers the T-gon products such as T-gon 200, T-gon K52 or T-gon CP230.   These thermal insulators are rough, dependable and cover the widest range of performance needs.

For very high watt density applications that generate excessive heat, the printed circuit board itself can be made thermally conductive using our T-lam system. The system provides for free-standing thermally conductive pre-pregs, core laminates and metal based circuit board laminates.  These products are designed into single, double and multiplayer printed circuit boards.

Our customers depend on us to design, manufacture, and ship on-time the highest thermal performance products.  Our exceptional customer service, competitive pricing and quick shipping demonstrate our commitment to customer satisfaction.

RF Foam - Broadband Microwave Absorbing Foam

The R&F Products Division of Laird Technologies offers a complete range of foam products for the microwave design engineer. The RF Foam series can be made in a variety of thicknesses to cover the entire microwave frequency range. Thicker foam performs at lower frequencies. RF Foam can be optimized for reflection loss or insertion loss.  It is used to reduce interference in antennas and microwave systems.  The following product offerings are available:

RFLS - Single layer lossy foam optimized for insertion loss. Insertion loss ranges from 1-50 dB/in. Thickness ranges from 3,18 to 114,3 mm (.125 to 4.5").

RFML - Multilayer foam made up of 3 RFLS layers. This graded approach gives good broadband  absorption over a wide frequency range.

RFRET - Reticulated foam with a continuously graded lossy coating. It provides the optimum in broadband reflectivity performance at the lowest weight.

Features/Benefits

Standard Sheet Size: 609,6 x 609,6 mm (24" x 24"). Larger sizes and die cut components are available.
Thickness Range: 3,18 mm (.125") through 114,3 mm (4.5") are available
Electrical Performance Reflectivity: -20 dB over specified range based upon thickness (RFRET 19,05 mm (.75") is -20 dB from 6-100 GHz)
Electrical Performance Insertion Loss: Customer specified from .25 to 50 dB
Custom Products: Weatherproof coatings, custom textile covers, and structural foam versions are available
UL94 VO versions are available
Applications: Minimize sidelobes of antennas; useful for EMI reduction in microwave boxes and components; and provide shielding between microwave transmitters
