SEMICON West 2016
Durex exhibited at SEMICON West 2016 in July. Our exhibit featured new thermal solutions focused on next generation wafer processing and back-end assembly equipment.
Randy Nelson, Durex Industries' General Manager said "As next generation semiconductor devices continue to become smaller, faster and more complex, requirements for precision thermal solutions increase. Durex continues to develop new thermal technologies such as aluminum nitride (AlN) Z-Axis™ Thermal Solutions. Z-Axis thermal solutions are 3-dimensional, allowing the integration of multiple heater layers, RTD sensors, RF grid, ground plane, and vacuum and cooling channels in a single monolithic solution."
At SEMICON West, we enjoyed many creative technical discussions with engineers and scientists visiting the Durex exhibit. ♦
Sensor Element Selection Guideline
"There are 4 primary sensor types: Resistance Temperature Detectors (RTD), Thermocouples (TC), Thermistors and Integrated Circuits (IC). Each sensor type has performance and cost attributes that make them the best solution for specific types of applications. To help with the selection process Durex created the Sensor Element Selection Guideline.
Durex helps customers select the best sensor element for their application, then designs sensor assemblies that optimize the performance of the sensor element. ♦

Foodservice Temperature Sensor Applications
Durex has been in the business of designing and manufacturing temperature sensor solutions for over 30 years. Understanding the Foodservice Equipment Industry requirements and supplying OEMs with custom temperature sensors is a Durex success story.
Foodservice Equipment applications include the same types of equipment that most of us watched our grandmothers and mothers use in their kitchens. The difference being that restaurants, institutions, and other food-away-from-home kitchens require highly accurate, repeatable and robust cooking equipment.
All types of fryers, griddles, ovens and other cooking equipment use temperature sensors. Durex’ RTD and thermocouple sensor solutions are designed to provide the accuracy, repeatability, and industrial robustness that OEM’s require for their equipment.
A fryer example would be a recent sensor design that incorporated 2 RTD sensor elements and 1 thermocouple sensor junction. Each sensor element needed to be isolated from each other. For optimum performance, each sensor element had to be located in the sensor assembly with a high degree of precision and repeatability.
Designing robust sensor probes and assuring production repeatability is one of the reasons that Durex is a preferred sensor partner with Foodservice Equipment OEMs. ♦
CNC Machining High-Level Predictive Analytical Software
In response to requirements in their next generation semiconductor equipment, Durex recently implemented CNC Machining High-Level Predictive Analytical Software as a quality improvement tool.
David Christopher, Quality Manager led the implementation project team and described the value of the Predictive Analytical Software in this way.
“To meet Durex’ expected growth plans and improve machining quality, the predictive machining software package provides part-by-part feedback for CNC machining operators on the dimensions measured by CMM and data-reporting. Real-time information on dimensional performance to tolerance as well as data -driven trends and tool performance can now be seen well ahead of any impact to the product. With CMM data reporting, the software package will provide dynamic analysis of variation for machining, specifically on critical dimensions. This will be used by operators and engineering to dial in parameters on equipment, provide optimal performance, elimination of scrap, and meet tightening product quality standards.”
Durex customers have responded positively to the software implementation. Thank you to David and the CNC Process Control Implementation Team. ♦
Aerospace - Defense - Security
Durex is an experienced industry leader in supplying robust innovative thermal solutions for the critical applications in the Aerospace, Defense, and Security industries.
Most aerospace, defense, and security thermal applications require heating components that are critical to the successful operation of a sub-system. The thermal solution must address a combination of harsh environments, heating 3-dimensional components, precision accuracy, fast response, robustness and other design specifications. Customer test and validation requirements vary with application and intended end use.
Durex designs and manufactures thermal solutions using our core heater and sensor technologies combined with other electromechanical components to supply customers with turnkey assemblies. Standard validation, manufacturing, and quality processes align with industry requirements. Thermal solutions may range from low-temperature de-icing applications using flexible polyimide heater technologies to sensors used in high-temperature engines and turbines. ♦
