Page 31 Dazor Intros Digital Magnification System
St. Louis, MO — Dazor, a manufac- turer of task lights and lighted mag- nifiers, has released its latest digital benchtop magnification system, CODA. The streamlined and easy-to- use system has been designed to pro- vide magnification during produc- tion, for quality control and for many other inspection applications.
Eunil H.A. Presents Very High Accuracy TableCoating Machine
Chula Vista, CA — Eunil, a manufac- turer of automated peripheral SMT equipment, has released its ECM- 350 Table Coating Master, a highly- accurate off-line machine for small- quantity batch production. As PCBs are the foundation for
electronics in products for automo- tive, consumer electronics, communi- cations, and industrial and energy applications, they are often exposed to damaging environments that range from moisture, dust, and harsh chemicals to extreme thermal cycling and vibration.
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)
ECM-350 automated PCB coating system.
Coating provides the protection
needed to function in these environ- ments. Features of the ECM-350 include
an accurate and consistent gantry robot (x-axis) and table robot (y-axis), the ability to fix various products at Multi JIG, exhauster to inhale odor, and an internal UV lamp. Common uses for the coating
are to inhibit leakage and short cir- cuit due to humidity and contamina- tion, to inhibit corrosion, to improve fatigue life of solder joints to leadless packages, and to provide mechanical support for small parts preventing damage from mechanical shock and vibration. The machine is designed to pro-
duce repeatable results, increase pro- ductivity (high throughput and re- duced labor costs), improve material utilization, and improve quality with
little to no masking. Contact: Eunil H.A. Americas,

SEMICOSIL® 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
A: Optimized dispensability for faster cycle times B: Available packaging: pails and carts C: Processability validated with reputable equipment manufacturers

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®
CODA combines a high-defini-
tion 1080p camera with the compa- ny’s patented “floating arm.” The ar- ticulating arm allows the user com- plete control over the camera’s orien- tation. CODA delivers direct-connect monitor viewing with high-definition resolution. Images are viewed real-time at
60 fps with no latency or delay in video streaming. A variety of quality lens options provide user selection of optical specifications given the in- tended application and workspace constraints. Due to CODA’s streamlined de-
base. The system provides users with
high magnification power, a large field of view and a large working area. Its applications include all in- spection tasks, small component as- sembly, production, repairs, work vi- sualization, and group training. Ac- cording to the company, payback from improved productivity, early de- fect identification, error reduction, and worker comfort can be achieved
quickly with CODA. Contact: Dazor Lighting Solu-

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.
