Technology continues to offer us data that can save lives !!!

Saturday, February 27th, 2010

As we all watch carefully the turn of events it reminds us how important technology is and the impact data can have on human life. Friends we at Solid State Inc have at our fingertips the science and are committed to assist future green engineers by providing a broadline of manufacturers which can push the limits of technology in the decade ahead .  We await the news from customers and friends in Chile and also watch carefully how the Tsunami will affect the Pacific Rim. 

One reporter on CNN described how oceanagraphic devices can measure changes in the ocean and it sparked my interest to read on what kinds of technologies are designed for these exact purposes.  GlobalSpec, the search engine for engineers, describes various instruments which are used to detect oceanagraphic events.

Oceanographic instruments measure various physical characteristics of the world’s oceans. They include devices such as thermometers, fluorometers, depth sensors, acoustic current meters, echo sounders, tide and turbidity gauges, coastal buoys, meteorological instruments, water samplers, and salinometers.

Oceanographic instruments provide important data about tides and currents, as well as water quality characteristics such as chemical composition and salinity. Oceanographic instruments can also provide data about weather conditions; natural disasters such as typhoons, hurricanes, and tsunamis; and a myriad of sea life. The data collected from these devices can be shared with scientists all over the world using satellite communication and computer networks. There are several collaborative projects, such as the Argo project, which share real time data gathered by their oceanographic instruments with anyone interested in it. 

Oceanographic instruments give scientists and researchers an enormous amount of invaluable information. The devices range from very simple buoys to very complex and sensitive sensor systems that capture the unique characteristics of a body of water. For example, turbidity devices measure the quantity of solids in the water, such as phytoplankton or sediment, or dissolved particles such as pollutants or chemicals. Fluorometers detect the presence of impurities by measuring fluorescence, or the emission of particular wavelengths of light. Salinometers use the electrical conductivity and specific gravity of the water to measure its salt content. Other oceanographic instruments measure physical characteristics such as depth from the surface of the water to the ocean floor, the speed of water currents, and the height of tides. An acoustic doppler current profiler is a sonar device that uses transducers to detect and record the water’s current velocities across a range of depths. These current profilers are used to detect potentially damaging underwater tornadoes or measure the amount of freshwater melting off icebergs.

Other sonar-based oceanographic instruments include echo sounders, which use sound waves to measure the distance from the surface to the bottom of the sea floor. Echo sounders are frequently used to evaluate the quantities of fish in a particular area of the ocean, but they can also be used for navigation. High resolution bathymetry, or details of the ocean floor itself, can be made using a multibeam echo sounder attached to an autonomous underwater vehicle or submersible. 

Buoys are some of the most ubiquitous oceanographic instruments, serving as simple maritime markers and navigational aids to more complex profiling devices. Profiling buoys are designed to sink below the surface to measure temperature and salinity. Profiling buoys sink at a predetermined rate and resurface after a set period of time. Waverider buoys are specialized oceanographic instruments that measure the movement of the water’s surface to determine characteristics like wave height and period. Tsunami buoys can detect sudden changes in the ocean’s water pressure and are used as part of an early warning system in the Pacific and Indian Oceans.  

Other oceanographic instruments are used for meteorological or climate studies. Weather buoys measure air and water temperature, wind speed and direction, barometric pressure, and wave height. These buoys may also be configured to transmit data to satellite networks, allowing meteorological centers to make real time predictions and warn people of impending storms.

We challenge our customers, veteran engineers, young aspiring scientist to push the limits in their fields.  Create the products using the visions and interest they have,  use their resources and to continue their contributions.

Bergquist pre-applies Bond-Ply 450 to PCBs

Saturday, February 27th, 2010

Found this interesting article regarding Bergquist Edited by the Electronicstalk editorial team Feb 23, 2009

The reflow-resistant thermal interface tape saves product manufacturers from manually applying thermal interface material after assembly.

This streamlines production, allowing to quickly bond the metal-core PCB to a heatsink avoiding laborious attachment of individual screws or clips.

The pre-applied Bond-Ply 450 tape is designed to retain its adhesive properties after passing through reflow soldering, allowing the assembly to be directly attached to a heatsink.

Release of the back-side liner is also unaffected by soldering temperatures.  It is available only as a pre-applied thermal interface for T-Clad circuits. It is 0.127mm thick and is rated for continuous use from – 30 to +120C.

High bond strength to low-energy surfaces such as aluminium heatsinks and a variety of plastics assures secure assembly, even for products used in harsh environments.  The Bond-Ply 450 is available in both standards as well as customised T-Clad circuits.

These include outlines such as power rails and star- or square-shaped LED boards, as well as a limitless variety of sizes for use in markets such as architectural, automotive, medical, military, signage or aerospace.

The path to successful new products

Thursday, February 25th, 2010

Is your company finding it hard to develop new products? If so, you might try learning from the masters.

We found after surveying more than 300 employees at 28 companies across North America and Europe, that the businesses with the best product-development track records do three things better than their less-successful peers: They create a clear sense of project goals early on, they nurture a strong project culture in their workplace, and they maintain close contact with customers throughout a project’s duration.

The teams in our study that embraced these tactics were 17 times as likely as the laggards to have projects come in on time, five times as likely to be on budget, and twice as likely to meet their company’s return-on-investment targets.

While we focused on companies in the automotive, high-tech, and medical-device industries, we believe that product makers of all stripes could benefit from our work.

Here is a closer look at what we found:

Keep it focused

Whenever project requirements were clearly defined and communicated to teams before kickoff, the project had a greater chance of success.

In our survey, 70 percent of the people working on high-performing projects, those that ranked in the top quarter of a performance index linking best practices to outcomes said they had a clear view of the project’s scope from the beginning, compared with just one-third of poor performers. We found that not thinking through a project’s scope early on say an appliance maker asks developers to design a new cooking range in the four-burner category but then later expands the project to include ranges with six burners can create delays.

The teams with a clear understanding of project requirements appeared better able to make trade-offs between product performance and things like cost, time to market, and project risk. Only 19 percent of poor performers said they had the necessary information to make those decisions.

Top performers also focused more intensely than low performers on staffing projects with the right people: 47 percent of the former researched employees’ skill sets before the project kicked off to ensure the project team was well rounded. None of the low performers did.

Nurture a project culture

The top-performing companies in our survey also nurtured a strong project culture by making product development a priority. They made more of an effort than the laggards 39 percent versus 12 percent to minimize staffing disruptions due to external demands and to staff projects adequately. When people with critical skills become overburdened, they often decide on their own which of their many projects is the most important, a decision best made at the management level.

Two-thirds of top performers compared with 39 percent of poor performers said team members focused more on the success of the project than on satisfying the needs of their job function when those interests competed. They also were more likely than the laggards 44 percent versus 17 percent to give team leaders responsibility for reviewing team members’ job performances.

Three years ago, a North American medical-device maker in our study began an effort to stem market-share losses. Recognizing that one of the company’s underlying problems was that project culture was weak, the device maker gave senior team leaders ownership of projects from beginning to end, as well as authority over staffing, personnel reviews and, in some cases, profit-and-loss responsibility. The new structure encouraged leaders to make better decisions, resolve conflicts quickly and reduce delays.

Talk to the customer

The successful innovators in our study kept in close contact with customers throughout the development process. More than 80 percent of the top performers said they periodically tested and validated customer preferences during the development process, compared with just 43 percent of bottom performers. They were also twice as likely as the laggards to research what, exactly, customers wanted. That made them better able to identify and fix design concerns early on, minimizing project delays.

The medical-device maker we mentioned created a matrix to identify and weigh the importance of various product features to different customer segments. It then tested trade-offs between product performance and things like price by bringing in surgeons and other medical specialists to use the product in simulated clinical settings. That allowed the team to fine-tune the product well before launch.

The result? Three years after starting its effort to shore up market share, employee satisfaction with product development increased, time to market improved for all projects up to 40 percent in some cases and overall gross margin rose six percentage points.

AVX: 55mΩ part can replace two devices in some designs…

Wednesday, February 24th, 2010

From AVX Press

AVX Corporation, a leading manufacturer of advanced passive components and interconnect solutions, has expanded its TPM Series of multi-anode mirror design tantalum capacitors that offer improved robustness and feature low ESR – including the industry’s leading performance device.

The D sized TPM Series 47µF/25V part offers the lowest ESR in the industry -just 55mΩ. In comparison, a single anode part in the same package has an ESR of 100mΩ and the E case device (same footprint, bigger case size) provides a minimum ESR of 80mΩ. By reducing the ESR value by 30%, the new capacitors offer a significant improvement in filtering capability, even to the extent that one part can sometimes replace two standard single anode devices.

AVX has developed the first mirror design multi-anode parts rated at 35V. The TPM Series D 22µF/35V is suitable for use in circuits with high current and voltage spikes where the profile is limited to just 3mm. It is ideal for automotive battery applications running on 12/14V with low impedance, where it offers enhanced robustness and lower ESR than single anode capacitors. In addition, since the D and E case sizes use an identical footprint, the pad design does not need to be changed if the D-case part can be used to replace the larger capacitor. For higher operating voltages the TPM D 10µF/50V with an ESR of 140mΩ is also available.

All parts meet the requirements of AEC-Q200, which is a key requirement for automotive designs in Europe.

Vishay’s New-Generation, Ultra-Precision VHP100 Bulk Metal® Foil Resistor Wins Product of the Year Award from Electronic Products Magazine

Tuesday, February 23rd, 2010

MALVERN, PENNSYLVANIA — Feb. 8, 2010 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced that the new generation of its VHP100 hermetically sealed Bulk Metal® Foil resistor, which sets a new industry benchmark for ultra-high precision, has won a Product-of-the-Year award from industry magazine Electronic Products.

Presented yearly, the Product-of-the-Year awards are bestowed by the editors of Electronic Products on those new products they feel are among the most significant of the thousands of new products introduced during the year.

For applications that require the very highest standard of precision, Vishay’s new-generation VHP100 is the first and only resistor on the market to stay within a 30-ppm max. resistance variation over the entire military temperature range of – 55 °C to + 125 °C. This means that the device’s resistance value will never deviate by more than 30 ppm (0.003 %) total.

Furthermore, all VHP100 resistors will automatically maintain maximum temperature-related ratios of 60 ppm (0.006 %) over the entire temperature range regardless of whether the resistors are all at different temperatures and whether the different temperatures are caused by environmental temperature variations, locally different heat generated by adjacent power components, or even self heating in power dissipation. Similarly, model VHP101 maintains a maximum spread of 10 ppm total over the instrument range of + 15 °C to + 45 °C.

In addition to its low TCR, the VHP100 provides tight tolerances to ± 0.005 % (50 ppm) and a load-life stability of ± 0.005 % (50 ppm) typical for 2,000 hours at + 70 °C and 0.3 W. An even tighter tolerance to ± 0.001 % (10 ppm) is available on request.

Vishay’s VHP100 offers an immediate answer to many challenging resistor applications previously thought to be unsolvable, including compact portable resistance standards, on-board resistance standards, feedback devices for operational amplifiers, precision voltage dividers, meter multipliers, precision bridge resistors, and decade voltage dividers. As a result, the devices open entirely new areas of design where the use of resistors had not been considered.

The ability of the VHP100 to minimize changes in resistance when the resistor is subjected to stress factors (mounting, handling, shock, and vibration) ensures ultra-high performance for tight metrology specifications. As applications requiring this level of performance also require immunity to humidity, the device features a hermetically sealed metal and glass enclosure to protect the resistive element, and is oil filled to improve the thermal dissipation path to the outside.

The VHP100 resistor offers a resistance range of 100 ohms to 150 kilohms and a shelf-life stability of ± 0.0002 % (2 ppm) typical through at least six years. Vishay Foil resistors are not restricted to standard values, and can be supplied with “as required” values (e.g. 1.2345 kilohms vs. 1 kilohm) at no extra cost or delivery time.

While other resistor technologies can take several seconds or even minutes to achieve a steady-state thermal stabilization, the VHP100 utilizes a unique manufacturing process that results in thermal stabilization time of less than 1 second, and a 1.0-ns rise time, essentially without ringing.

With its extremely tight specifications, the VHP100 is virtually a secondary standard that can be carried in sets for daily or periodic calibration of factory measurement equipment. The VHP100 is also available with laboratory- and metrology-level precision and long-term stability with additional in-house oriented processes. These include chip stabilization, special TCR plotting, additional treatments for ultra-stability, and special post-manufacturing operations (PMO), such as temperature cycling, short-time overload, and accelerated load life, which are uniquely applicable to Bulk Metal Foil resistors. 

Special construction allows the devices’ copper leads to pass through a glass seal to the outside of the enclosure. This positions the more malleable solder-coated copper leads on the outside of the package and minimizes the thermal EMF at the internal termination-to-resistor junction assembly. 

With the VHP100, only a minimal shift in resistance value will occur during its entire lifetime. Most of this shift takes place during the first few hundred hours of operation and can be eliminated by PMO; virtually no change is noted thereafter. The overall solution cost is thus lowered, since the very high stability of the VHP100 allows designers to eliminate other passive and semiconductor components that would otherwise be needed to compensate for the lower stability provided by other resistor technologies. 

In addition to its excellent stability characteristics, the VHP100 withstands electrostatic discharges of up to 25 kV for increased reliability and offers a non-inductive (less than 0.08 microhenries), non-capacitive design. The VHP100 offers current noise limit of less than 0.010 microvolts (RMS) per volt of applied voltage (less than or equal to -40 dB), thermal EMF of 0.05 microvolts per deg. Celsius typical, and a low voltage coefficient of less than 0.1 ppm/V.

“Already one of the biggest suppliers of MHz crystal products, AVX/Kyocera merged with a company called Hertz to add unique kHz design capabilities to its own expertise in high-reliability ceramic packaging and competitive price structuring,” said Akira Honda, Product Marketing Manager at AVX. “These new devices offer equivalent performance to similar industry standard devices, but benefit from our ultra-reliable / cost competitive ceramic packaging technology.”

ST3215SB, the reflow compatible tuning fork crystal resonator has a frequency tolerance of +/-20ppm, a maximum ESR of 70kΩ and an operating temperature range of -40°C to +85°C.

Vishay: Photodiode-Based Ambient Light Sensors

Wednesday, February 17th, 2010

To assist customers in understanding the advantages of using ambient light sensors in their applications, the Optoelectronics group of Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has added a new streaming video product demonstration to its Web site.Vishay’s ambient light sensors feature an exclusive infrared filtering epoxy technology to match the spectral sensitivity of the human eye, with minimal sensitivity to light beyond the visible range. This helps to prevent interference from the infrared component of natural light and artificial lighting such as incandescent and halogen light bulbs. The new five-minute video features a brightness level test which highlights the superior performance of Vishay’s TEMT6200FX01 over competitor and standard silicon phototransistor parts.

The demonstration shows that with different light sources, other technologies show a significant deviation in the brightness level detected. Vishay’s TEMT6200FX01, however, most closely matches the spectral sensitivity of the human eye by showing nearly no deviation. This level of performance allows Vishay’s ambient light sensors to be used for automatic control of LCD brightness in consumer electronics, where they increase user comfort level and reduce power consumption by turning on keypad backlights only in low ambient conditions, and controlling LCD display brightness to optimize viewing based on ambient light.

Pushing the Limits: Creating Green Jobs

Sunday, February 14th, 2010

We are all hearing the buzz words regarding the next green technology. With our countries advanced resources we challenge young engineers and our established known design houses to push the limits.

The oil and natural gas industry needs no stimulus; we need no earmarks. We are not asking anything from the government, but one simple proposition–opportunity. Today, and for many years, oil and natural gas resources in the United States have been off limits. Over a year ago, the Congress finally lifted the moratorium that put off limits over 80 percent of all the oil and natural gas resources in the United States. Unfortunately, the Department of the Interior (DOI) has to approve the expanded leasing of those lands. And for the first year in office, they have not done that. We run the risk that we’re not going to have enough lands to develop and to find these resources going forward. We believe it’s important to the future of this country, during these tough economic times, to develop these resources and find the jobs and produce the energy the American public wants. Again, all we need is an opportunity. We’re not asking for a handout or anything from taxpayers–just give us the opportunity to go look, to go find and then to develop these resources for the benefit of all Americans.
