New Keithley Online Tutorial Provides Information on Ultra-Fast I-V Measurement Applications

Keithley Instruments has created an interactive applications overview that provides instruction and insight into a variety of semiconductor measurement applications that require ultra-fast I-V measurements. The new overview is titled "Ultra-Fast I-V Applications".

Ultra-fast I-V sourcing and measurement have become increasingly critical capabilities for many semiconductor technologies. Using pulsed I-V signals to characterize devices rather than DC signals makes it possible to study or eliminate the effects of self-heating (joule heating) or to minimize current drifting in measurements due to trapped charge.

The applications overview includes sections on integrated high speed sourcing and measurement; a discussion of voltage, current, and timing parameter ranges; a description of the built-in interactive software provided in Keithley's ultra-fast I-V test solution; and a detailed discussion of ultra-fast I-V applications. Built-in links provide easy navigation, and many of the schematics and other diagrams enlarge automatically when scrolled over to allow easier reading.

Ultra-fast I-V testing is appropriate for a growing range of semiconductor test applications, including:
  • CMOS device characterization (charge pumping, self-heating, and charge trapping)
  • NBTI and PBTI characterization, modeling, and monitoring
  • Testing non-volatile memory devices such as PCRAMs
  • Testing of compound semiconductor devices and materials (laser diodes and thermal impedance measurements), and
  • Characterization of nanotechnology, MEMs devices, and solar cells.

Direct on-line measurement of density and concentration

Eliminates the need for expensive laboratory analysis.

Endress+Hauser has introduced the Liquiphant M, a density meter that provides on-line measurements, eliminating the need for extensive and expensive off-line procedures and laboratory measurements. A built-in density calculator can be end user customized with complex tables and mathematical interdependencies, allowing the meter to provide the same kind of density and concentration measurements once possible only with lab instruments.

Because the Liquiphant M provides on-line measurements, it allows control systems to react much faster to changing process conditions. Instead of waiting for results to come back from the lab, a control system can take corrective action immediately by performing closed-loop control.

Calculating Density
The Liquiphant employs a mechanically oscillating fork with two tines that are each excited to resonant frequency. The frequency changes when the fork is immersed in any liquid. If the vibration falls below a predetermined frequency, the sensor reports the covered state to a subsequent switching electronics. The tines are excited by a piezoelectric drive. The resonant frequency depends on the moment of inertia of the fork as well as the membrane stiffness, and the frequency measures approximately 1000-1200Hz in air.

Changes in resonant frequency are directly interrelated with the density of the medium. In a lower medium density, such as liquefied gas, the resulting resonant frequency is higher than in more pronounced densities like water. The electronics of the Liquiphant can measure this change in the resonant frequency. The density of the medium can also be calculated taking temperature and process pressure into consideration.

Concentration can be calculated in mass or volume units. For example, "Degree Brix" is a measuring unit for the specific density of liquids. This is particularly used in the food industry to determine the sugar content in fruit juices and beverages, or in oil production to measure the salt concentration in tanks.

The customer can customize the Liquiphant M for many density and concentration applications including but not limited to:
  • Content measurement and concentration (sulphuric acid, sugar, alcohol, etc.)
  • Quality statements (mineral oil, milk, etc.)
  • Purity indication
  • Product identification
  • As a changing variable indicating the metabolism in relation to kinetic statements (reaction rate)
  • As a basic variable for physical calculations or simulations
  • For clarification of how much material is contained in a given volume.
The Liquiphant M Density meter is capable of providing analytical process information on-line and in-line according to customer requirements. It offers solutions for a variety of applications including process optimization, quality monitoring and reduction of waste. The meter can also be used for monitoring of preliminary, interim and final products during blending operations - and for verification and documentation of process steps. Because it reduces the need for offline laboratory measurements, it also improves plant availability and speeds response to changing conditions.

Manufacturing solar panels

Competitive Advantage Through Complete Visibility and Control Over Solar Panel Manufacturing Process

HelioVolt has implemented the GE Intelligent Platforms Proficy® Software suite in its new thin film solar PV module manufacturing plant. The company, based in Texas (US) chose GE’s software to increase plant yield and throughput, while meeting strict control and traceability requirements. With the solution, they will be able to achieve a rapid return on its investment and gain immediate visibility into its manufacturing processes.

HelioVolt is producing thin film solar PV modules for commercial rooftop, utility-scale ground mount, residential, BIPV and custom installations. It is the first thin-film company combining high-efficiency products with low-cost manufacturing capabilities to create a new generation of Copper Indium Gallium Selenide (CIGS) based solar modules. Thin film technologies reduce the amount (or mass) of light absorbing material required to create a solar cell. This can lead to reduced processing costs from that of bulk materials.

“Our automated and fully integrated manufacturing process, from substrate to final module assembly and test, allows us to reach high manufacturing efficiencies and low costs more rapidly than other competing technologies,” said Iga Hallberg, Vice President of Business Development for HelioVolt. “The Proficy solution can help us to keep plant yield and throughput high, as well as ensure quality. Ultimately, this will lead to better and more cost-effective solar modules for our customers.”

As a new company, HelioVolt needed a solution that is easily replicated to new plants, but also needed the solution to scale data storage for up to 30 years to satisfy warranty requirements. In addition, high volume manufacturing was a must to drive cost down while maintaining quality.

“HelioVolt had some tight project deadlines to meet to satisfy their investors, so only a turnkey solution supported by rapid implementation services would work for them,” said Erik Udstuen, Vice President of Software and Services for GE Intelligent Platforms. “Proficy offers a complete Lean Manufacturing solution that provides the flexibility to add equipment and optimized work processes as HelioVolt scales its business.”

The software system employed at HelioVolt is made up of five core elements of the Proficy suite providing the company with robust redundancy, enhanced data security, reliable information and increased control of every aspect of operations through access to critical data. By delivering web-based visualization and real-time analytics, operators are able to increase efficiency and optimize production processes in real-time resulting in reduced costs and increased profitability.

“GE’s experience in manufacturing as well as the company’s ability to get a complete system up and running in a short time frame were key to working with HelioVolt,” concluded HelioVolt’s Hallberg. “We are looking forward to a bright future in the solar business and we think this software solution will help us get there.”

LVDTs successfully monitor structures in marine environments

Waves of the Irish Coast: Caisleán Nua.Monitoring cracks in structures in coastal environments such as sea-walls, harbours and tunnels calls for transducers that are precise, robust and can withstand the corrosive marine atmosphere.

RDP Electronics Ltd has decades of experience in providing Linear Variable Differential Transducers (LVDTs) that provide accurate measurement of even the smallest movement in cracks, to provide essential diagnostic data that can be used to determine the cause and where necessary prompt appropriate remedial action.

To combat the corrosive atmosphere in marine locations that can be more aggressive than total immersion in seawater due to the combination of saline water and oxygen that accelerates corrosion, it is essential to specify stainless steel transducers. For long-term tests, 316 stainless steel generally recognised as ‘marine grade’ stainless steel is preferred and usually LVDTs are additionally specified as rated up to IP68 and 230 bar.

LVDTs which are unguided types, rather than captive, are mounted on pins drilled either side of the crack. Locations often call for long cable runs from the LVDT’s location to instrumentation, which is achievable due to the 4 – 20mA output of the transducer.

Directors re-elected

At the annual general assembly of CiA (CAN in Automation), three directors have been re-elected: Arnulf Lockmann (Janz), Heinz-Juergen Oertel (Port), and Holger Zeltwanger (pictured right). They lead the non-profit association since 2005.

The CiA members also nominated the Technical Committee and Business Committee delegates (esd, Janz, Port, Schneider, Vector, and Wachendorff).

The CiA international users’ and manufacturers’ group, which supports the international standardized Controller Area Network (CAN) serial communication system (ISO 11898 series) has more than 500 members worldwide.

“The members requested activities to improve the standardization of CANopen device descriptions in order to simplify the selection of products,” says Holger Zeltwanger, the re-elected Managing Director. “This could lead to a data base, in which the system designer may search for specific device functionalities.”

Test software combines electrical & mechanical analysis

During APEX 2010 Las Vegas ( NV US; 6-9 April 2010), ASTER Technologies, are to introduce the first Design for Test (DfT) software to combine electrical and mechanical analysis.

It has been developed to address a new vision of the DfT market that has to solve the many challenges that developers face today, such as: shrinking release cycles, budget compression and improvement in product quality.

TestWay, the world-wide reference coverage analysis tool that allows users to quantify and qualify the test coverage for a wide range of inspection and test equipment, has been enhanced to address the problem for companies that subcontract the manufacture and test of their products, but need to know how to optimize the physical test access in order to achieve maximum test coverage.

The “probe analyzer” is an interactive, rules-based routine specifically designed to assist the Layout engineer or Test developer to identify any possible probe location based on the copper surface, which is useable for a physical access. Access constraints, spacing checks, test points assignment, use of the largest probe size, pin offset and Agilent’s bead probes are taken into account in accordance with company specific guidelines

Once the potential probe placement has been identified, TestWay can estimate the test coverage for ICT and FPT based on the measurement capabilities of the targeted test equipment. The “probe analyzer” also generates a comprehensive accessibility report that clearly states whether adequate probe locations were identified for each net, highlighting mechanical rules violation, so that this information can be fed back to design to support improvements. By reading the access report interactively with the layout viewer, colour coding is used to assist the design and test engineer to graphically browse the non-testable nets in the design.

TestWay provides a sophisticated level of coverage analysis by allowing users to define the test line and combine ICT or FPT with complementary test techniques such as AOI, AXI, BST, FPT, ICT, MDA and Functional Test. It estimates the theoretical coverage aligned to various test strategies, prior to test development, in order to identify areas where test coverage can be improved, so that electrical rules could be applied to identify DFT violations that limit the test efficiency.

The ability to estimate coverage that is aligned to the mechanical layout constraints of the PCB, allows users complete visibility of what can realistically be achieved, so that the effectiveness of the completed test programs can be realized.

Christophe Lotz, Managing Director of ASTER Technologies, said, “Within the new electronic world where the people who design is no longer the same as the people who produce, the market expects a new generation of tool that is useable by both groups. Now, design & test engineers can identify in a matter of minutes, a missing test point, and understand the consequences in terms of test coverage”.

ASTER proposes a wide range of products that support electrical DfT and test coverage analysis. This allows users to select a configuration, which meets their immediate requirements. TestWay is a scalable product from TestWay Express for coverage estimation and measurement, up to TestWay-Classic that provides additional features such as a fully programmable environment capable of supporting customer’s rules checking, test optimization criteria, advanced reporting and Boundary-Scan test generation.

Longer warrenty and higher temp for encoders

Reflecting the total confidence in the quality of its wide range of WDG encoders and systems, German manufacturer Wachendorff Automation GmbH has extended its warranty from 3 to 5 years as well as increase the working temperature range of all WDG encoders to those used for military specifications.

They saw the warranty expansion as a logical extension to the positive feedback and extremely favourable returns statistics from many satisfied users.

WDG products include incremental and absolute encoders, guided belt measuring systems and draw wire type linear measurement encoders. In particular, WDG series encoders cover incremental shaft and hollow shaft encoders from 24mm to 145mm in diameter with standard quadrature resolution up to 25000 pulses per rev. WDG series absolute encoders include single- and multi-turn variants with up to 18-bit resolution and output options of SSI, CANopen and Profibus-DP in both optical and highly robust magnetic designs. A wide and flexible choice of mounting styles include synchro-flange, clamp ring and screw-flange mechanical interfacing.

The decision to increase the standard temperature rating places the rugged and durable standard WDG encoder product line in operating temperatures from -40°C to +80°C with storage up to +100°C.

All Wachendorff WDG encoder products and systems are characterised by high reliability and resistance to vibration with IP68 rated housings available for the toughest of environments. Application areas for the product includes cranes, lifts, road marking machinery, agricultural and construction vehicles.

Wachendorff is represented exclusively in Britain by Variohm EuroSensor, which provides complete sales and technical support across the full range of products with stock delivery available on many standard products and the ability to coordinate special custom encoder requirements with Wachendorff.

High dynamic range cameras based on solar cell technology

The image shows a 40W light bulb, imaged on the left with a conventional CCD sensor and on the right with the FX4 HDR sensor.

A new range of cameras from Stemmer Imaging use a sensor based on solar cell technology to allow imaging from scenes which simultaneously contain both very light and very dark areas. This makes them ideally suited to use in environments with a very high dynamic range, or where there are strong and unpredictable brightness fluctuations. The new FX4 HDR (High Dynamic Range) sensor from IDS produces a logarithmic signal output. This enables fine differences in brightness to be imaged even in very bright scenes, without saturation, in a similar way to the human eye. Most of the USB and all of the GigE versions (HE, RE and SE) of the IDS uEye family of industrial cameras feature an FX4 HDR sensor version.

The FX4 HDR sensor features a patented pixel structure that provides a truly logarithmic output with effective suppression of fixed noise and gives a dynamic range of 120 db. This equates to a 1000 times greater brightness ratio (ratio of the highest brightness value to the lowest brightness value that can be imaged in a scene) compared to conventional linear CCD sensors, which typically have a dynamic range of 60 db.

The logarithmic response not only means that large changes in brightness in light areas of a scene cause only small changes in image brightness, but also prevents saturation in the image and ‘blooming’. Conventional linear CCD sensors can become saturated, then additional light leads to overexposure, which causes blooming, where charge from overexposed pixels ‘overflows’ into neighbouring pixels, causing whole areas of an image to appear white with the loss of image data.

High dynamic range applications include automotive/traffic, welding, paints/glossy finishes and payment kiosks. In traffic applications the sensor may need to identify detail in the dark interior of a vehicle while the headlights are on. In welding, details of a weld seam or the object being welded can be imaged even in the presence of the bright weld arc. Reflections and glossy spots on reflecting surfaces such as paints require increased dynamic range sensors. Payment kiosks for petrol stations or ATM withdrawals are frequently poorly illuminated and therefore require high dynamic range sensors to adequately image people using the machines. Applications involving very strong fluctuations in brightness are often related to security and monitoring, such as monitoring on a sunny day with fast-moving cloud cover.

The sensor provides a full 12-bit colour depth output to take full advantage of its reduced noise characteristics. This allows contrast to be adjusted to enhance the visual display of images in applications where the dynamic range of the scene is less than that of the sensor. For added versatility, the sensor can be set to give a linear output similar to conventional sensors for conventional imaging. The FX4 sensor does not use integration methods and so operates completely in real time at 30 frames/sec.

Licensing agreement for refinery process models

Invensys Operations Management has entered into an agreement with ExxonMobil Research and Engineering Company (EMRE) that allows Invensys to sub-license a suite of EMRE's refinery process models to third parties. The suite of models will be delivered through Invensys Operations Management's market-leading SimSci-Esscor® optimisation software, using its ROMeo® solution to enable clients to model and optimise process units.

"With depressed demand, decreased margins and increased environmental mandates, refiners no longer have the option to simply operate at maximum throughput," said Sudipta Bhattacharya, president and chief executive of Invensys Operations Management (right). "Over the course of the coming decade, we will see a drastic shift in the oil industry as refiners constantly optimise their operations in the face of changing feedstock and energy costs, product specs and margins. Refiners will increasingly rely on accurate modeling technologies to construct a refinery-wide picture and assess the financial impact of different operating scenarios. Our SimSci-Esscor optimisation software and ROMeo solution, combined with EMRE process models, enables refiners to make improved economic decisions throughout the refinery, from crude feed to final product blending."

While traditional modelling solutions can only simulate individual process units or provide point solutions to solve a specific problem, Invensys Operations Management's SimSci-Esscor solution provides a scalable software environment that enables companies to optimise refinery-wide performance, as well as other aspects of refinery profitability, such as utilities and instrument/equipment health monitoring. Additional benefits are derived from leveraging the data generated by rigorous models to enhance planning and scheduling decisions, leading to increased refinery margins.
"These modeling improvements allow refiners to better optimise their operations," said Charles Darnell, global manager for optimisation at ExxonMobil Research and Engineering Company. "We use ROMeo technology in our plants for multiple applications and continue to work with Invensys to develop improvements in this technology."

Device profile for pumps

CANopen device profile for pumps (CiA 450) released

The Task Force (TF) pumps of the CAN in Automation (CiA) international users’ and manufacturers’ group has published the version 1.0 of the CANopen device profile for pumps (CiA 450). The profile specifies the CANopen interfaces for generic and liquid pumps. On request, the CANopen interfaces for process vacuum and turbo vacuum pumps will be specified, too. The specification is based on the bus-independent profile for pumps developed by VDMA (German association of machine builders).

The profile defines the pump configuration data, control and status information as well as the values measured by the pump electronics. Operation behavior of the pumps is controlled via the defined state machines. Via Emergency messages failures, warnings or alarms are indicated to the user. Also multiple pumps may be operated via the same CANopen interface. The profile is currently available for CiA members.

Meat analyser at IFFA

NDC Infrared Engineering will be showing the simple-to-use InfraLab at-line NIR Meat Analyzer at IFFA (8/13 may 2010 Frankfurt/Main D). At-line measurement using NDC’s proven NIR (Near Infrared) technology, provides a rapid and accurate measurement of moisture, fat or protein in meat, without the need to send samples off for time-consuming laboratory analysis.

The InfraLab can be calibrated to standard laboratory methods such as Gravimetric Oven or Karl Fischer for moisture, Soxhlet (for crude fat), Werner-Schmidt or Weibull Stoldt (for total fat), NMR (for fat) and Kjeldahl for protein. This ensures laboratory accuracy without the costs or the need to use the often-hazardous chemicals associated with laboratory methods. In addition the grab samples used by the InfraLab are much larger than those used by many laboratory techniques making them much more representative of the actual manufacturing process.

Easy to use, and with automated sample detection, the InfraLab requires no special user skills. Measurement data can be stored in the instrument and/or downloaded to a PC at any time for in-depth analysis by tracking measurement values product by product over long time periods.

New software for switchgear

Rittal’s new Power Engineering software tool

Power Engineering v4.1, is Rittal’s new version of planning and configuration software for type-tested low-voltage switchgear of their Ri4Power systems, Form 1, Form 2-4 and Ri4Power Form 1 ISV. The software offers quick and easy generation of quotations and bill of materials with better assembly information and the capability to view the side of the assembly, where part numbers and their location within the system are indicated.

Software includes project handling that ranges from an automatic generation of bill of materials via price determination up to material ordering. By means of comprehensive import and export functions it is possible to add third party products, required for distribution, to the software database. Special enclosure designs can be optionally stored in the software as own field types.

Comprehensive help functions lead the user through the programme and explain the necessary steps. When entering some parameters, bill of orders and drawings can be generated for individual field types. The user is able to add further Rittal products or other articles from a self-created article master at any time during field configuration.

After configuration of the individual fields a CAD view can automatically be displayed, printed or exported if required. The generated bills of materials, whose content can be freely generated, can optionally be printed or exported as a file.

Included in the bill of materials are new technical brochures; Tightening Torques for flat-PLS bus bar system and Assembly Instructions for Ri4Power low voltage switchgear.

White paper on “Tuning the Forgotten Loop” published

We can tune PID controllers, but what about tuning operators? This white paper describes a new method for combining archived video, recordings of operator actions and process historians for training and tuning operators.

An operator’s job has often been described as hours of boredom interrupted by moments of sheer panic. What the operator does during panic situations often depends on how well he or she has been trained, or “tuned.” Advanced tuning of an operator can yield better outputs, higher quality, fewer errors and a wider response to fluctuating operating conditions. This white paper explores how to improve operator actions, and offers a method for doing so.

As part of cost reduction and increased automation, fewer humans are involved with operating larger and larger plants. Thus, those few operators who are left have huge responsibilities, and their actions can have a major effect on plant output and, ultimately, business performance. “Tuning the Forgotten Loop,” by Steve Rubin, president of Longwatch, covers the problems facing operators, including alarm floods, trying to diagnose problems in the plant from HMI displays, lack of attention, boredom, being faced with abnormal situations, and human error.

With the increased emphasis on Six Sigma quality issues, new technologies such as the Smart Grid, increasingly complex HMI screens, and insurance and regulatory issues, operators are under increased pressure to perform. But few tools are available to train and “tune” operators. Simulators help, but nothing beats giving operators visual feedback of their responses to alarms, incidents and accidents.

This white paper suggests that video recordings from the plant, video recordings of operator consoles, and data from plant historians can be combined to provide operators with an “instant replay” of their actions, or the actions of experienced operators faced with the same situation. Being able to reconstruct exactly what happened during an incident aids in troubleshooting, training and “operator tuning.
