Ultra-Low Silicone Thermal Gap Filler Provides

Posted on October 21, 2009 by

ARLINGTON HIEIGHTS, ILLINOIS, USA, October 21, 2009: Hill Tech Sales, a leader in components for electrical power conversion and thermal management today is introducing ultra-low silicone gap fillers to its line of thermal interface materials.

Hill Technical has added new TP-S3LS ultra-low silicone gap fillers to its line of thermal interface materials. TP-S3LS pads contain less than 50 parts per million of silicone while providing 3.0 W/mK of thermal conductivity between hot components and their heat sinks. The gap filler’s minimal silicone content makes it suitable for use in silicone-sensitive applications including medical electronics, laser optics and telecommunications where silicone-based out gassing can lead to contamination and condensation issues or leave oily residues that interfere with process applications. The TP-S3 family of materials was developed by Chang Sung Corp. and is manufactured by Dongyun Electronics in South Korea.

Pads of TP-S3LS material are soft and compliant for easy compression and filling of air gaps between irregular mating surfaces. The material’s Shore 00 hardness is 55. TP-S3 pads can be used in temperatures up to 200°C, which exceeds the use range of silicone-free gap fillers. The material has a UL 94 flame class rating of V-0. Its dielectric breakdown voltage is over 5.0 kV.

New TP-S3 gap filler material is available in 210 x 297 mm (8.3 in x 11.7 in) sheets or die-cut parts. Standard sheet thicknesses range from 0.5 to 5.0 mm (0.020 in to 0.196 in).  Pricing for standard flat TP-S3LS sheets starts at $0.10 per square inch, which is below the cost of other 3.0 W/mK thermal gap fillers now available. Lower priced TP-S materials are also available with thermal conductivities of 2.0 and 1.0 W/mK.

Step by step procedure for UV Lamp Replacement in UV Reflector Assemblies

Posted on October 19, 2009 by

ARLINGTON HIEIGHTS, ILLINOIS, USA, October 20, 2009: Hill Tech Sales, a leader in components and subassemblies for UV curing today published a “step by step procedure for UV Lamp Replacement in Reflector Assemblies

This procedure can be seen in detail in the FAQ section of the Hill Technical Website, below are steps listed:

  1. A qualified person following proper lockout procedures must perform lamp replacement.
  2. Turn power off. Be sure that the irradiator and lamp have cooled before removing the lamp.
  3. Disconnect all power and high voltage cable from the LIA.
  4. Remove irradiator cover by removing both knobs at each end of the LIA and lifting out the assembly by its handles.
  5. Place the LIA upside down on its handles
  6. Remove one metal diffuser. Loosen the screws on the lamp holder to release the top bracket.
  7. Disconnect the lamp leads and pull lamp out of the LIA.
  8. Clean the replacement UV lamp and reflector liners with a lint free cloth and denatured isopropyl alcohol. Use latex or vinyl gloves during this step to keep the lamp free of any fingerprints.
  9. Place one lamp lead and end fitting through the mounted metal air diffuser and on top of the lamp holder.   Place the loose metal air diffuser around the other lamp end and place the lamp end onto the lamp holder.

10.  Remount the metal air diffuser and place the top bracket over the lamp end and tighten the top bracket.

11.  Connect lamp leads to ceramic standoffs.

12.  Place the irradiator back in place and tighten the four knobs and reconnect the high voltage cable by matching index to index and screwing the connector cable down completely.

Ultra miniature, cost effective, 1 watt DC/DC converters

Posted on October 19, 2009 by

ARLINGTON HIEIGHTS, ILLINOIS, USA, October 16, 2009: Hill Tech Sales, a leader in components for electrical power conversion today is introducing Ultra miniature, cost effective, 1 watt DC/DC converters.

These 1 watt products feature continuous output short circuit protection – a critical safety feature that protects the load circuit and the converter from dangerously high current levels in ultra miniature packages:

AM1DR-RZ (SIP7: 19.50 x 7.20 x 9.50mm) and AM1MR-Z (DIP14: 20.30 x 10.16 x 6.90mm) operate at the most commonly designed fixed inputs of 5, 12, and 24VDC (with ±10% tolerance).

 Highly regulated and protected output voltages 3.3, 5, 7.2, 9.12, 15VDC feature a tight load regulation of ±0.5% to ensure that stable voltages are delivered throughout the operating range, under all types loading conditions.

 Each of the 18 models in the AM1DR-RZ and AM1MR-Z series feature input/output isolation of 1000VDC, allowing these versatile power supplies to be configured for reverse polarity on the output or to be wired in series to create higher output voltages.

 Operating within an industrial temperature of -40°C to +85°C without derating, both the AM1DR-RZ and AM1MR-Z series are engineered to meet the IEC 60950-1 standard for use with indoor or outdoor telecommunication networks or cable distribution systems.   The components MTBF of greater than 1,500,000 hours further supports their use in applications where access for maintenance is limited or restricted. 

 RoHS compliant, all models undergo 100% production testing of their parameters to ensure the high reliability, while remaining competitively priced

Inverter Driven Centrifugal Blower for Clean Room Applications

Posted on October 19, 2009 by

ARLINGTON HIEIGHTS, ILLINOIS, USA, October 19, 2009: Hill Tech Sales, a leader in components for electrical power conversion is announcing Inverter Driven Centrifugal Blower used for Clean Room Applications.

These blowers are designed to have a high output while running quiet with minimum energy input. The high efficiency designed motor allows only a ten degree temperature rise at its rated air output of 375 CFM at 0″ H2O. The inverter outputs a constant 230vac, three phase at 60hz thus allowing for a common input of 220vac, single phase at either 50 or 60Hz. This enables the blower to have a constant output in countries throughout the world.

An IEC 60320 shrouded male plug terminates to the blower with a 15 foot International Harmonized 3 x 1.00mm2 cord set. The rotor is dynamically balanced and incorporates ball bearings providing a quiet long life. The air inlet and outlet accommodate 4″ flexible duct. Construction, materials and finishes enable us to meet MIL-SPECS and operate in harsh environments as well as in the office, lab or clean room.

See some of the custom blowers Hill Technical has created for their customers at www.hilltech.com
