Rogers Releases New Advanced Circuit Material
Rogers' Advanced Circuit Materials Division (ACMD) has released its new RO2808 high frequency circuit material. With a dielectric constant of 7.6, the ceramic-filled PTFE material offers the stability and high frequency performance of LTCC. It features low loss tangent of 0.002 or less and can be supplied as 1-mil thick boards to support low profile designs. RO2808 laminate features high moisture resistance, high reliability and excellent high frequency performance.
Rogers ACMD will also offers other chip packaging materials including RO4000 laminates and prepregs, ULTRALAM 3000 laminates and bondply, and R/flex 1500 adhesive film.
Rogers' Thermal Management Solutions Division provides HEATWAVE metal matrix composite (MMC) material for overcoming difficult thermal management challenges through effective and efficient dissipation of excess heat. Also on display will be the COOLSPAN thermal interface materials (TIMs) and electrically and thermally conductive adhesives (ETCA).
HEATWAVE MMC is an aluminum silicon carbide (AISiC) composite material that is ideal for thermal base plates and heat spreaders. Available in a wide range of thermal conductivities, it features excellent specific stiffness, tightly controlled coefficient of thermal expansion (CTE), and has considerably lower density than other thermal management materials.
COOLSPAN TIMs are non-silicone thermal conductive greases that help dissipate excess circuit and component heat efficiently. These greases feature excellent thermal stability, reliable high temperature performance, high thermal conductivity, and superior demateability properties to silicone products. They can be used in both TIM-1 and TIM-2 applications, and multiple dispensing options are available.
COOLSPAN ETCA is a thermally and electrically conductive unsupported silver-filled B-staged epoxy adhesive film. This material is targeted at microwave circuit and heatsink applications where an electrical ground path is desired. Other applications include die attach, printed circuit board fabrication and advanced material composites.

RapidWrap Removable Thermal Insulation Covers Now Feature Aerogel Materials
LIT Industries, Inc., a subsidiary of Pacor, Inc., has released aerogel insulation material as a filler for their RapidWrap removable thermal insulation covers. These insulation materials are made from nanoporous aerogels that provide characteristics different from traditional materials. Aerogels are available for service temperatures from -460°F (-273°C) to 1,200°F (649°C). They provide two to eight times the insulation value for the same thickness compared to traditional materials. Aerogel RapidWrap covers offer a thin profile that will allow the use of removable covers in tight spaces that previously would have gone unprotected. Aerogels are also hydrophobic, providing outstanding resistance to moisture. They also provide excellent resistance to flame spread and smoke emission.
RapidWrap covers are specifically designed for easy installation, removal and reinstallation. Featuring a durable outer layer and various closure systems, RapidWrap covers have proven highly durable in harsh environments. RapidWrap covers are fabricated using field verified dimensions that are translated into CAD generated drawings. Covers can be designed and fabricated for most any conceivable shape or size. The ease with which the covers can be removed and reinstalled eliminates the need to reinsulate for routine maintenance or when repairing equipment problems.
REOTEMP Releases Adjustable Angle Bimetal Thermometer
REOTEMP’s adjustable angle bimetal thermometer allows for easy temperature monitoring from virtually any position with a complete 180° dial adjustability (360° case rotation). This rugged adjustable angle thermometer is well-suited for most industrial applications.
