Gore Improves Thermal Performance of its Direct Air Cooling Filter

W. L. Gore & Associates, Inc., has introduced a new membrane media for its line of GORE® Cooling Filters that increases thermal performance while providing strong environmental protection and reliability. The new GORE® Cooling Filters improve thermal cooling while reducing both capital and operating costs in wireless base stations, MCPAs, base band units, power cabinets, switching systems, and other outdoor electronic enclosures.

The benefits of using the new GORE® Cooling Filter are two-fold — improved cooling efficiency and reduced costs. Constructed with a new membrane technology, the filter improves thermal cooling approximately 20 percent by allowing higher airflow through the filter. At the same time, the membrane protects the electronic components by preventing fine contaminants such as dirt, dust, and sand from entering the enclosure. By increasing airflow while reducing potential contaminant damage, the GORE® Cooling Filter improves overall reliability of telecommunications infrastructure.

GORE® Cooling Filters reduce both capital and operating costs in several ways. First, a significant cost savings is achieved with a new lightweight frame designed into the filter. With these new frames, the filters are significantly lighter and less expensive to purchase and ship. Also with the new media, the filter lasts about 20 percent longer than its predecessor, yielding additional OPEX savings. Second, unlike bulky heat exchangers and energy-consuming air-conditioning systems, direct-air cooling systems have very few moving parts, which further reduce equipment maintenance costs. Finally, the new membrane technology reduces operating expenses by lowering the filter pressure drop by 60 percent, which in turn reduces the amount of energy required by fans to efficiently cool sensitive electronics.

The technology behind the new GORE® Cooling Filter is based on a proprietary expanded polytetrafluoroethylene (ePTFE) membrane. This microporous membrane allows cool, clean air to flow into the cabinet while filtering out harmful contaminants. Expanded PTFE membrane has a 99.0 percent particle filtration efficiency at the 0.3µm level (1cm/sec). GORE® Cooling Filters can incorporate the high-performance Gore filtration media into either a lightweight frame or a rigid anodized aluminium frame, providing the most reliable protection possible for a variety of applications. Cabinets fitted with GORE® Cooling Filters easily pass the most stringent requirements, including IP55 and NEMA 3R.

GORE® Cooling Filters significantly improve Mean Time between Failures (MTBF) because of their ability to lower the internal cabinet temperature over HEX and to increase corrosion protection over standard filters. These filters can be customized to fit small to large base station units for mobile communications as well as wire-lined cabinets such as ADSL and power enclosure applications. According to Dr. Wilson Poon, research associate at Gore, “Using Gore’s ambient-air cooling system with our new membrane technology is a cost-effective solution, whether it is being incorporated into a new product design or retrofitted into an established product. Available in either a lightweight or aluminium frame, GORE® Cooling Filters allow an equipment manufacturer to increase its competitive advantage in the marketplace without compromising optimal performance.”

StratEdge Unveils Series of Small Outline Thermally Enhanced Packages for Power Semiconductors

StratEdge, announces the introduction of a new family of small outline thermally enhanced molded ceramic packages for power semiconductors.  The new line of packages can be used for silicon, silicon carbide, gallium nitride, and other compound semiconductors in power integrated circuit applications.  Specific devices include amplifiers, discrete transistors, and diodes where greater than 0.5 Watt power is consumed.

These thermally enhanced packages are designed for reliability and to mitigate the inherent stresses of brazing dissimilar materials together.  All materials used in the packages have matched coefficients of expansion.  They are assembled using a glass-to-metal seal process combined with gold germanium brazing, resulting in a rugged and reliable package.  The packages can handle temperatures up to 360 degrees Celsius.  A hermetic seal provides enhanced reliability for the device and offers protection from harsh environmental conditions, meeting military standard requirements.  Packages in this series are sealed with metal or ceramic lids that have gold-tin solder preforms.


These packages incorporate copper composite bases or copper inserts for enhanced thermal dissipation.  Devices are mounted directly to the metal bases thus providing excellent electric ground to the backside of the chip.  They provide superior electrical performance for frequencies up to at least 6 GHz.  For controlled impedance devices, transition designs with higher frequency performance can be utilized.

Packages are available in various shapes, sizes, and lead counts.  All can be provided with gull wing-shaped leads for surface mounting.  A popular package is the two lead G1010M-2C supplied with copper insert.  The G1010M-2C has a 0.100 inch square (2.5mm square) outline with a 0.030 inch (0.75mm) by 0.055 inch (1.4mm) die attach area.  Pricing at 10,000 units is about $6.26 each.  Pricing may vary due to order configuration, the price of gold, and shipping destination.

“These new packages, combined with our Power Package Series with thermally conductive beryllium oxide (BeO) ceramic, give our customers a variety of packages to choose from to package their high power devices,” said Timothy Going, president and CEO of StratEdge.

StratEdge’s new thermal power package can be seen at the MTT-S Show in Atlanta, Georgia from June 17-19 at booth 2039.

Cambridge University selects S.E.T. KADETT for LCoS applications

S.E.T Smart Equipment Technology, has announced the successful installation of a KADETT High Accuracy Placement and Bonding system at Cambridge University (UK), department of Engineering. The KADETT has been purchased thanks to a grant of Cambridge Integrated knowledge Centre for various R&D applications and especially for the assembly of LCoS (Liquid Crystal On Silicon) devices using UV-cured adhesive.

Liquid Crystal on Silicon (LCoS) is a reflective micro display using a Silicon Backplane. It is an alternative technology to LCD or Plasma applied for projection television. LCoS technology enables much higher resolution images at a lower cost. The placement of the circuitry behind the pixel allows a high fill factor and consequently high light efficiency. The images are less pixilated because the circuitry is behind the pixel.

“The glass and the silicon IC are aligned and pressed together using the KADETT, then the adhesive is cured with UV light. Subsequently, the device is filled with Liquid Crystal. The S.E.T. KADETT is a flexible and robust tool ideal for our R&D applications”, says Dr. Neil Collings at the Electrical Engineering of the University of Cambridge.

The SET KADETT Semi-Automatic Bonder is a flexible and open platform for accurate assembly and bonding of devices on a large variety of substrates. The machine performs accurate Pick & Place functions as well as Flip Chip bonding. A wide range of bonding processes including In-Situ Reflow, Thermo Compression, and Adhesive joining are available with temperature up to 450°C and force up to 75N.

The flexible architecture of the S.E.T. KADETT enables the integration of many processing modules such as a UV glue curing system, Ultrasonic bonding head and many others. “Its easy and quick changeover between the various process configurations is of primary interest for research environment where adaptability and multi-user compatibility is essential“, said Gilbert Lecarpentier, International Product Manager at S.E.T.

The UV Glue Curing System is available as an option and brings light to the process area through a fiber. Producing a 20 mm diameter spot with 80 W/cm², it provides complete control for step curing of assembly adhesive. Parameters such as intensity, dose, and exposure time are controlled by the software.
