Page 37 Versum Releases Gas Temperature Control System


Tempe, AZ — Versum Materials has introduced its GASGUARD® eV tem- perature control system, which has been designed to deliver reliable fab-


The temperature control system


contains the company’s trusted gas delivery technology with an ECC heater/controller, two blankets and two heat traces in a platform that can eliminate the time spent specify- ing, installing and commissioning third-party equipment. The integrat- ed system also allows fabs to scale manufacturing with the assurance that the components of the delivery system will not need to be upgraded or replaced. The GASGUARD eV system’s


newly redesigned heater blanket has single-piece construction for both the heater and insulation, dual voltage (120 or 208-240V supply) and over-

Qioptiq Intros High-Speed Zoom Lens for Automated Imaging


Waltham, MA — Qioptiq, an Exceli- tas Technologies® company, has in- troduced its Fetura+™ advanced zoom lens. The enhanced Fetura+ en- ables high-speed and reliable optical performance in the machine vision and inspection markets.


The heat-conducting SEMICOSIL®


ELECTRONICS AND ELECTRICAL DEVICES. By Mr. William Russell, WACKER Marketing Manager


Under the trade name SEMICOSIL® 961


TC, which offers thermal conductivity of 2.0 W/mK, WACKER expands its thermally conductive silicone portfolio by introducing a new gap filler material for electronics and electrical device applications. The constantly increasing demand for heat dissipation between two substrates with high tolerances requires a thermally conductive gap filler material which is easy and cost effective to process, durable and effectively protects functionality.


These applications include:


• Automotive and transport electronics • Electric and hybrid electric batteries (cell potting)


• Power electronics • Consumer electronics


SEMICOSIL®


Fetura+ high-speed zoom lens. Useful


for high-throughput


micro-inspection, non-contact dimen- sional measurement and general au- tomated imaging applications, the zoom lens is built with a linear rail coupled with precision optics that allow it to travel through its 12.5:1 zoom range in less than one second. Due to its design, the zoom lens also offers a service life of over 1,000,000 cycles and delivers exacting repeata- bility in any orientation. The Fetura+ is fully-compatible


with the company’s Optem FUSION lens system optics and accessories. The zoom lens can be customized with added features or modified housing requirements. With fully- programmable operation, the lens can be integrated easily as the opti- cal core of a complete, custom imag-


ing assembly. Contact: Excelitas Technologies

1 961 TC is a highly filled,


two-part silicone rubber that cures at room temperature via a platinum- catalyzed addition reaction to form a soft silicone elastomer. The cured rubber achieves a thermal conductivity of two watts per meter kelvin (2.0 W/mK) and, at the same time, is electrically insulating.


Before it cures, SEMICOSIL® 961 TC


is a non-sag material. However, its viscosity decreases with increased shearing; for example, during mixing and metering. Its shear-thinning properties allow the silicone rubber to be easily dispensed in bead form using standard dosing equipment. The high shear-thinning characteristic also ensures very high dosing accuracy, along with increased dispensing speeds compared to similar products currently in the market.


Notable material features and benefits:


• Cures at room temperature or faster at elevated temperatures


• Faster cycle times • Low volatile content (<350 ppm) • UL 94 V-0 rating (WACKER test result)


• Constant properties between -50 °C and +180 °C after cured


• Electrically insulative • Very good vibration dampening


• High thermal and thermal-shock resistance


• Improved service life of mixing and metering equipment due to low abrasion


SEMICOSIL® 961 TC ensures optimum A B

heat transfer from the electrical circuit to a heat sink. The gap filler material is first applied to the heat sink. The circuit board is then pressed onto the heat sink or fitted by means of a vacuum process. During compression, a continuous film forms that conforms securely to the surfaces of the two adjoining parts. In this way, surface irregularities and tolerances can be perfectly evened out. Furthermore, the film surface area maximizes the contact of the two adjoining parts and thus enhances heat transfer properties.


961 TC silicone


filler from WACKER is applied directly to the heat sink. Once the electrical circuit is pressed on, the gap filler cures to form a soft, cushioning silicone layer that optimally transfers heat to the heat sink.


Thanks to its soft consistency, SEMICOSIL®


temperature protection reliability through redundant bimetallic switch- es for a more precise delivery of heat- ed gases to the fabrication tools. Versum has expanded the mon-


itoring and control links between the heater/controller and AP11 con- troller to encompass benchmark gas delivery control that provides users with enhanced uptime, simplified troubleshooting and increased con- troller reliability. The unit also has a single power


feed (with an optional dual power source) and integrated GFRI protec- tion to lower installation costs. Even with the additional functionality, the system has a reduced footprint that re-


sults in more usable floor space in the fab. Available as either a single- or multiple-source system, the tempera- ture control system has Class 1, Divi- sion 2, ATEX, CE, and CSA approvals, as well as other certifications. The GASGUARD line of gas de-


livery systems includes automatic, semi-automatic and manual configu- rations from single-source to multi- ple-cylinder source and purge sys- tems.

961 TC ensures a reliable,


tight fit even if there are frequent temperature changes and vibrations. SEMICOSIL®


961 TC can be used


over a wide temperature range as its properties remain unchanged between -50 °C and +180 °C. High thermal and thermal-shock resistance and the ability to absorb vibrations are important performance factors for applications in automotive electronics and other sensitive electronic devices.


SEMICOSIL® 961 TC is a two-


component system that offers nearly identical viscosities for each of the two components to minimize waste often associated with mixing two- component materials with vastly dissimilar viscosities. Despite its high filler loading, it has a comparatively minor abrasive effect on the mixing and metering equipment used to apply it. This means there is less abrasive damage to feed pumps, for example, than is usually the case with highly filled silicone rubber. Consequently, significantly longer service lives of mixing and metering equipment and major cost advantages in processing are possible.


The new SEMICOSIL® 961 TC silicone


rubber gap filler material contains hardly any volatile components. In terms of fire-safety properties, tests show that the silicone product meets the specifications for classification V-0 as per UL 94 of Underwriters Laboratories.
