Every electronics manufacturer wants stable production processes and precise monitoring of production parameters. In thermal processes such as soldering, drying or curing of electronic assemblies, reliable and reproducible temperature profiling is important for achieving high-quality results. Temperature monitoring in the challenging soldering process therefore has special significance. TiP300 is a new wireless temperature sensor technology developed by pro-micron and tuned to the specific requirements of condensation soldering with the CondensoX series from Rehm Thermal Systems (http://www.rehm-group.com). The technology was exhibited for the first time under the name WPS 2.4 (Wireless Profiling System) at the Rehm booth at this year’s SMT in Nuremberg.

The WPS 2.4 is a temperature measurement system, a unique innovation worldwide, used for precise detection of the reflow profile in condensation soldering processes. The innovative temperature sensor technology makes it possible to check and to document at little or no expense the machine and process capability in thermal processes exactly and reliably, without affecting the ongoing production.

The temperature sensor of the WPS 2.4 with firmly attached antenna is fixed to the carrier of the CondensoX soldering systems from Rehm. No power supply is necessary. As the name of the system suggests, no cables are needed to transmit the temperature from the sensor to the receiving antenna. This is done via a radio signal. Evaluation electronics deliver temperature readings live to the system control via a digital interface. In the recorder software, also newly developed by Rehm, the temperatures are plotted graphically in real time. The transmitting and receiving antennae were optimized by pro-micron for this application. The WPS 2.4 therefore guarantees continuous monitoring of soldering processes up to 300 °C and provides a new quality of temperature detection.

Advantages of the WPS 2.4 at a glance:
-100 % process monitoring
-Simple and continuous quality verification
-Lower cost for profile measurements
-Greater transparency in the detection of machine and process capability
-No disruptive cables

The measuring system is available for the first time in the CondensoX series from Rehm Thermal Systems as an option for new installations and as a retrofit solution. „With the WPS 2.4 we put our clients in a position to meet the growing demands of complete traceability and of industry 4.0“, assures Michael Hanke, Chief Customer Officer of Rehm. In the future, the system will also be available for other processes such as convection soldering, annealing and drying.

Rehm Thermal Systems was founded in 1990 by Johannes Rehm and is a provider of reflow soldering systems and drying systems for the electronics industry as well as a manufacturer of fast firing systems and solar dryers for the metallization of solar cells. With Simply. More. Ideas. our goal is to become technological leaders in all areas of production and offer our customers sustainable, future-oriented products.

2D temperature distribution measurement

Measuring the temperature distribution of the top gas in blast furnaces

2D temperature distribution measurement

t-matriX for the temperature measurement inside the blast furnace

At Metec, IMI Z&J Technologies GmbH will present the new 2D gas temperature measuring system t-matriX for blast furnaces. The system measures the distribution of the top gas temperature in two dimensions. This provides much more information than systems making spot-type measurements. Due to the solid sensor equipment and the fact that it is installed outside the blast furnace, the system is also less costly and less maintenance-intensive.

The t-matriX system consists of several interlinked transmitter and receiver units of identical design, distributed along the circumference of the blast furnace. As they are installed outside the furnace chamber, they are accessible at any time. t-matriX uses the principle of acoustic pyrometry, i.e. the principle that the speed of sound in a gas changes as a function of temperature.

The system measures the time it takes for an acoustic signal to propagate between the transmitter and receiver units. From the individual, integral sound propagation times, the tomographic software of the system calculates the temperature distribution in the measurement plane. This technique no longer measures the top gas temperature at certain spots, as used to be common practice in the past, but in two dimensions across the entire furnace chamber. The system not only measures and calculates the temperature distribution. It is also designed to automatically determine hot spots.

The acoustic signal is generated by means of nitrogen. For this purpose, in one of the transmission and receiver units a solenoid valve is opened, releasing nitrogen which will flow through the unit now acting as transmitter. The resulting noise is recorded by a microphone in the transmitter and stored as a reference signal. The individual microphones of the other seven units will receive a broadband noise, which will be compared with the stored transmitted signal by means of a dedicated correlation technique. From this, the tomographic software will calculate and graphically display the temperature distribution in the respective plane. The system provides the results virtually in real time. The readings are updated every three to four seconds. The gas temperature measurements by the system are not influenced by radiation effects resulting from the heavily dust-laden atmosphere in the blast furnace.

In addition to the 2D analysis, the system provides various other advantages over conventional temperature gauges. No equipment is installed inside the blast furnace. The transmission and receiver units are mounted on studs outside the furnace chamber. All that is needed is a drill-hole in the refractory brickwork. The system can be serviced while the furnace is in operation.

To summarize the benefits: t-matriX provides a lot more information than a system that makes spot measurements. However, its life-cycle costs are significantly lower due to its solid sensor equipment and the low maintenance effort involved.

Blast furnace operators using this system in combination with IMI Z&J“s solution p-matriX – a system providing a three-dimensional image of the burden geometry – will benefit from highly valuable information about the processes going on inside the blast furnace, which was not available to them in the past. Both systems can at any time be retrofitted to existing blast furnaces, irrespectively of the type of blast furnace top.

LumaSense Introduces Rel-Rad™ Hybrid Technology for Cost Effective „Relatively Radiometric“ Thermal Imaging in Steel and Glassmaking Processes

LumaSenseInc.com: The new breakthrough hybrid imaging technology for non-contact temperature measurement, LumaSense Rel-Rad™, combines single point pyrometry and thermal imaging in a cost effective solution delivering „a thermal picture that’s worth a thousand pyrometers“

LumaSense Technologies introduced a new infrared imaging technology called Rel-Rad™ imaging („relatively radiometric“) that bridges the gap between single-point pyrometry and thermal imaging to deliver precise thermal images at half the cost of fully radiometric systems ( http://www.lumasenseinc.com ).

LumaSense’s Rel-Rad™ combines low-cost spot pyrometry with infrared thermal imaging technology to produce thermal images that are not fully radiometric but are „relatively radiometric“. By driving the thermal image palette through a radiometric pyrometer capable of precise temperature readings, Rel-Rad™ delivers relatively radiometric IR imaging at a significantly lower cost than fully radiometric imagers.

Infrared cameras have proven to be the ideal non-contact temperature measurement technology in extremely hot manufacturing environments, but the high cost of imaging systems is often a barrier for many customers. LumaSense’s new Rel-Rad technology makes accurate thermal imaging far more accessible, so operators can monitor an entire object or process instead of just a small portion. Through its LumaSpec R/T software suite for thermal analysis, the Rel-Rad technology can be readily integrated with existing industrial monitoring and control systems via the Open Process Control (OPC) interoperability standard for industrial automation.

The hybrid Rel-Rad thermal imaging technology is ideal for industries where it is critical to know the temperature of an object as well as uniformity across an object at that temperature. Many processes in metals and glassmaking industry using a single pyrometer to measure temperature can be improved with Rel-Rad technology, e.g. steelmaking processes like ladle preheat, torpedo car monitoring and annealing furnace operations. With the more precise temperature measurements that a LumaSense Rel-Rad thermography solution provides, the life of a pouring ladle or torpedo car can be extended by 20% and energy usage for preheat operations reduced by 10%.

„Rel-Rad makes the benefits of thermal imaging accessible to industrial customers who have been shut out by the high cost of traditional radiometric cameras,“ said LumaSense CTO, Brett Sargent. „The cost of a single thermal imager can exceed $25,000 USD, whereas our Rel-Rad hybrid imaging technology creates a reliable image for half the cost and provides more insight than can be obtained from a single temperature point. Our Rel-Rad solution can be applied to existing pyrometers in the field to enhance process performance, regardless of make and model. LumaSense’s broad portfolio of sensors for thermography combined with our extensive industry knowledge and integrated software puts us in an ideal position to deliver Rel-Rad solutions to our customers. The impact will be enormous as companies reap gains in energy efficiency, reduced raw materials costs, longer asset life and reduced downtime.“

LumaSense Releases New Pyrometry System for MOCVD Processes in LED Production

Temperature sensing solution for metalorganic chemical vapor deposition (GaN-based epitaxy) with true wafer surface temperature and reflectance instrumentation improves efficiency and yield in LED industry

LumaSense Releases New Pyrometry System for MOCVD Processes in LED Production

LumaSenseInc.com: New Pyrometry System for MOCVD Processes in LED Production

LumaSense Technologies, Inc. released the UV 400 and UVR 400 pyrometers, the newest generation of non-contact temperature measurement instrumentation for metalorganic chemical vapor deposition (MOCVD) processes in the rapidly growing LED industry ( http://www.lumasenseinc.com/EN/products/infrared-thermometers-and-switches/specials/pyrometer-uv-400-and-uvr-400.html ). The UV 400 and UVR 400 are in a unique position to help manufacturers using MOCVD improve efficiency and reduce waste in their LED manufacturing process.

Using a center wavelength in the UV spectrum (400 nm) these pyrometers make it possible to measure real wafer surface temperature, while traditional pyrometers are only able to measure the susceptor/pocket temperature under the wafer. This allows the most accurate and repeatable control of the wafer temperature which e. g. in LED production is critical to the final product wavelength and manufacturing yields. The wide temperature range of 650 to 1300 °C allows for measurement of various applications such as GaN buffer layer growth or multiple quantum well growth. The fast response time of up to 8 ms allows the measurement of fast processes. True photon-counting instrumentation guarantees the best achievable signal to noise ratio and stability. In addition to the UV 400 pyrometer, the UVR 400 features a 635 nm laser reflectometer, which enables the real-time measurement of the thickness and growth rate of the GaN layer (gallium nitride) during epitaxy growth.

LED’s are on a trajectory to take over as the primary source in the $60 billion lighting industry by 2020, and are a key enabler in displays for mobile devices, televisions and other products in the growing $1.2 trillion electronics industry. „With an 8,000+ system-installed base in the semiconductor industry and a nearly 2,000 MOCVD tool-installed base, LumaSense is without doubt a leader in temperature instrumentation in this industry,“ said Brett Sargent, Vice President and General Manager, Products & Solutions, LumaSense Technologies Inc. „The UV 400 and UVR 400 are now setting a new standard for MOCVD measurement all around the world as the instruments have proven to provide temperature measurements with reliable correlation between the measured process temperature and the final product wavelength. This will result in unparalleled yield gains and efficiency improvements for our customers.“

The LumaSense UV 400 and UVR 400 temperature sensors are developed specifically for GaN-based MOCVD epitaxy processes offering the following features: direct temperature measurement on the GaN layer using UV wavelength instrumentation to obtain reliable wafer temperature with PL wavelength correlation, capturing real time reflectance measurement using a fast pulsing light source, prevention of data skew due to delayed sampling (no shutter on and off) and residue temperature oscillation as seen in NIR emissivity-compensated pyrometers, minimization of noise in measurement using true photocounting instrumentation, and yield improvement through accurate true wafer temperature measurement. The new LumaSense pyrometers for MOCVD processes (metalorganic vapour phase epitaxy) in LED Production, UV 400 and UVR 400, can also be combined with the well-proven PhotriX pyrometer with concentric lightpipe from LumaSense to additionally control the reactor temperature. Either the UV 400 and UVR 400 alone, or in combination with the PhotriX pyrometer, provide the best possible measuring data and process control solution, as well as the best product quality and improved yield.

Santa Clara, California, March 14, 2012 – LumaSense Technologies, Inc. has introduced a new line of highly configurable thermal imaging cameras specifically designed for use in harsh environments ( http://www.lumasenseinc.com/EN/products/thermal-imagers-detectors-and-cores/stationary-thermal-imagers/stationary-thermal-imagers.html ). The MC320 line for infrared thermography features uniquely configured optics and detectors that enable the cameras to be tuned to specific infrared wavelengths and optimal performance to best suit a particular application. This flexibility means the MC320 platform is a cost-effective solution for a wide range of applications including process control, predictive maintenance, safety and critical vessel monitoring.

Integrating the infrared camera expertise acquired from Mikron Infrared Inc. and the Vanadium Oxide (VOx) detector technology recently acquired from infrared detector maker ITC, the MC320 line will become LumaSense“s flagship platform for its fixed industrial thermal imaging solutions. Leveraging this integrated approach between camera design, optics and detectors coupled with LumaSense“s comprehensive software will enable a wide variety of turnkey solutions for various industries such as energy, steel, glass, and refining, among others.

„One size does not fit all in the world of industrial infrared imaging,“ said Brett Sargent, Vice President/General Manager of Products at LumaSense. „The MC320 line enables LumaSense to offer highly accurate, flexible thermal imaging solutions to a wide variety of industries. With the MC320 IR imaging camera platform, we can cost-effectively customize the lens, power source, calibration profile and even the wavelength detected to provide the best possible temperature measurement solution.“

The majority of industrial thermal IR cameras on the market are long wave cameras operating in the 7-14 micron wavelengths, which are best suited to applications with lower temperatures and in environment without interference. Mid-wave cameras operating in the 3-7 micron spectrum are particularly effective for seeing through interference such as flames and also perform well when measuring the temperature of highly reflective materials such as glass and plastics, but historically have used exotic and expensive detector materials.

The new thermal imager platform MC320 for non-contact temperature measurement supports the widest range of mid-wave VOx based cameras available on the market today applying application specific wavelengths and temperature ranges. Each stationary thermal imager model is tuned to perform in the most demanding industrial applications providing the best sensitivity and thermal image quality (thermovision) available in this price range measuring on metal and ceramics, on non-metal surfaces, through flames and hot gases, and glass surfaces with typical applications in monitoring vessels and furnaces, rolling processes, rotary kilns, and quality monitoring in glass production.
