Connector Products & Innovations

Positronic manufactures the most popular styles of connectors: D-subminiature (D-sub), high power, rectangular, modular and circular. While standard D-sub connectors are able to perform the function needed for many applications, Positronic has also developed innovative Dual Port D-sub connectors to save board space, combo D-sub connectors to allow for power and signal, and waterproof D-subs for outdoor applications.

Positronic is at the forefront of global requirements for power supplies and connectors. Positronic power connectors provide reliable connection for battery and power supply in applications that range from cleaning machines to data centers. In fact, in the 1990s, Positronic was approached by industry consortiums to develop completely new power connector types. Today, we are innovating new modular power connectors, including those being specified for the Open Compute Project (OCP). OCP is an organization that is creating open standards for hardware in data centers.

The modular power connectors used by OCP, called Scorpion, are manufactured using a unique injection molding process. This process allows the customer to choose the modules and configuration that meets their specification, and Positronic delivers a one-piece tooled product that is ready to perform upon arrival. This prevents the customer from having to assemble the modules themselves.

Our capability to quickly modify existing designs or create new products to meet customer-specific needs is one of our core competencies.

120 Years of Technology Evolution Towards the Mythic 99% Efficiency!
Posted: 2020-9-29


From the very early days when power electronics equipment utilized vacuum tubes, power engineers have been concerned with energy efficiency, power optimization and how to make power supplies more reliable, smaller and smarter. Probably few of us remember the introduction of the Thyratron or the 1925 patent by Julius Edgar Lilienfeld for the Field Effect Transistor, but the electronics industry is full of amazing inventions and innovations all contributing to achieving the mythical 99% efficiency level.

With the growing concerns for the environment and for reducing energy consumption, the need to meet governmental regulations, and of course individual initiatives, the demand on power designers to develop very efficient power solutions has been great. But simultaneously, and creating even more difficulties, emerging applications have required smaller power supplies with unprecedented power density expectations.

The laws of physics are the laws of physics, and despite many evolutions in switching topologies, power designers have run into road blocks requiring a solution that is able to switch faster, with less power losses and if possible maintaining good performances at higher temperatures.

Despite technological advancements in conventional semiconductors, it became difficult to increase the switching frequency by a magnitude of 10 while reducing the physical size of the power supplies while also reducing power losses. Among the different routes taken to achieving this, the exploration of materials offering higher performance such as higher-energy electronic band gaps has revealed the potential of Gallium Nitride and Silicon Carbide. Both materials have been used before e.g. SiC diodes and GaN LEDs, but the use of Wide Bandgap FET appeared relatively recently in the power electronics history.

As for all new technologies, GaN FET and SiC FET went through the classic process starting with the Innovators, to the early adopters and now reaching the early majority. What is very interesting is that probably due to a large number of innovators, GaN and SiC manufacturing was very quick off the mark in addressing niches markets with a very high growth potential.

Wide Bandgap (WBG) technologies have been presented at many conferences but I consider the real kick-off to have taken place in 2018 when "challengers" demonstrated the commercial potential of WBG technology. It is impossible to name all of them but among the leaders promoting GaN, I would say that the Efficient Power Conversion (EPC) Idea to implement GaN in LIDAR (Light Detection and Ranging) was really interesting, especially with that technology becoming preponderant in the new generation of vehicles. 2018 was also the year in which USB adapter manufacturers started to consider implementing WBG. Navitas is another example of an innovative company, which in the early days pushed GaN integration to a higher level by packaging drivers and switches on same substrate. If intelligent GaNFET is becoming standard today, it was not the case when Navitas introduced that concept.

If WBG is a very promising technology, we should keep in mind another symbolic milestone for a technology called 'Digital Power' that emerged in 2003 as a promising technology. As it was for digital power 17 years ago, GaN, having started its journey only a few years ago has followed a similar path, gradually migrating from a 'technical curiosity' to a 'commercial product'. Digital power and GaN are both technologies that were challenged and highly debated when introduced to the market, and it is interesting to link both of them in this way, especially when the outcome of combining the best of the two technologies results in truly outstanding commercial products.

Step by step to maturity

As it is for any new technology - especially when disruptive – the transition from research level to high volume production is a long process, one that includes new learning for electronics engineers and in the case of GaN, the implementation of zero-voltage switching topologies requiring very specific drivers and new ways of controlling them. Despite the huge benefits of GaN transistors, for many years the lack of drivers limited the interest level from industrial designers. Thankfully, the increased number of semiconductors players investing in GaN in the last two years has made this technology simpler to implement.

Many technical barriers have been removed. Manufacturing processes have gradually been optimized to increase yield and reduce cost, quality processes specific to this technology have been implemented, and in November 2017 the JEDEC organization announced the formation of a new committee to set standards for Wide Bandgap Power Semiconductors (JC-70). Then, February 2019 saw the release of the publication JEP173: Dynamic On-Resistance Test Method Guidelines for GaN HEMT Based Power Conversion Devices. Step by step, the puzzle is being solved and if GaN has been widely used in LED and RF applications for many years, power supply manufacturers for commercial products deployment are now adopting it.

Digital power combined with GaN heads towards 99% efficiency

What makes power designers' lives so exciting is the ever-present levels of innovation making it possible to improve performance levels, thus contributing to reducing our environmental impact and the creation of a sustainable society. Combining the benefits of digital power with GaN performance and the ability to switch at high frequencies with low power losses makes it possible for designers to develop very high power density units. That combination results in smaller products with lower power dissipation that are ready for stringent, future regulations foreseen in the coming years (e.g. micro-amps for standby power). One practical example is USB chargers where by combining digital and GaN, several companies are in some cases almost tripling the power density for a standard USB charger. That is without talking about multi kilowatts power factor correction equipment fitting into an existing 500W footprint. We are all aiming to break limits and there is no doubt we are moving fast towards the 99% efficiency, but as power designers we have to consider a new dimension that includes a larger eco-system.

Smart power becoming a reality

WBG and digital power have brought strategic, exiting technologies to the power designers' toolbox, and every day we are achieving new limits, but in today's world and as an effect of the industry's transformation, power supplies have to be both energy efficient and perform equally well within the eco-system in which they are integrated. From a USB-PD +PPS for charging and communicating with a battery, to a huge factory automation system where all power supplies are dynamically controlled and optimized to reduce factory energy consumption, power supplies designers will have to include a new dimension when designing the next generation of power solutions.

If previously, the well-known PMBus communication between a power supply and a power/site manager was well understood, then including Machine-to-Machine (M2M) communication with direct control of the power supply is relatively new and only at the beginning of its journey.

Industry 4.0 will introduce a higher level of software integration and if many power supplies remain as standalone units, we foresee a significant number of applications requiring power supplies to interoperate within their eco-system in a very advanced way. Smart Power for a Smart Industry is becoming a reality, and a very exciting one at that.

In conclusion, Smart Factories will use Smart Power solutions designed by Smart Power Designers all aiming for 99% efficiency, but with another eye on the ambitious target of 99.99%!

PSMA Core Loss Studies
Posted: 2020-9-29

Over the past five years, the PSMA Magnetics Committee has sponsored five Special Projects to better understand the flux propagation in ferrites and the reasons why the performance of large inductor cores performed so poorly compared to the expectations based on published specifications from the suppliers.

The first three projects - PSMA -Dartmouth Core Loss studies- were undertaken by Dartmouth under the leadership of Professor Charles Sullivan and the results are available on the Magnetics Forum on the PSMA web site. Based on some of the insights from these projects formed the basis for the 2 most recent projects – PSMA- SMA Core Loss Studies Phase 1 and Phase 2.

The last two Core Loss Studies are now complete, and this article highlights some of the most interesting findings.  This article is not as comprehensive as the reports, and the reader is encouraged to read the full reports on the PSMA web site for more information.

PSMA–SMA Core Loss Study Collaboration

SMA Magnetics was interested in why large inductor cores performed so poorly compared to expectations based upon published specifications. At the the same time, PSMA was interested in flux propagation in ferrites and why the performance factor B*f was lower and peaked at a lower frequency for larger cores.

Charlie Sullivan (Dartmouth) recognized that there was significant overlap in these interests and arranged an introduction which resulted in the Phase I PSMA-SMA core Loss study. The findings of the Phase I study were so intriguing that a Phase II study followed, which built upon the data from Phase I.

The Phase I and Phase II test reports can be found on the PSMA website Core Loss Studies tab of the Magnetics Forum. The Phase I report is publicly available; Phase II is currently only available to PSMA members, and will be publicly available in late 2021.

PSMA - SMA special project – Phase I

The purpose of the Phase I PSMA-SMA Core Loss projects was to study the flux distribution within ferrite cores while operating.  The concept is that a small area internal to the core can be enclosed by a test winding inserted into drilled holes.  The voltage on the test windings shows the dφ/dt of the flux.

Initially, eight specially machined cores, two each of four materials, were made by Fair-Rite.  Three holes were drilled into each core so that flux in the innermost 1/9th of the core area could be compared to the excitation.  These cores were shipped to SMA for study.


Although the original scope was to test these eight cores, SMA drilled seven more 50 mm cores of various materials to provide a larger sample.

A surprising result for some of the cores was that the flux density in the center of the core was much higher than the average flux density, peaking at just over 2.5 times.  Further, it had a large leading phase.


PSMA - SMA special project – Phase II
Phase II was a larger study comprising five parts:

1. Large core testing–flux propagation in ferrites

Several large cores were drilled with nine holes so that three sets of wires enclosed progressively smaller internal areas.  In this way, the flux and flux density can be measured in three shells and the center for comparison with the excitation voltage.



Two other large cores were drilled so that the voltage can be measured around any of 49 segments.  Each segment is the same size, 1/49 of the total, so one-to-one comparisons could be made.

2. Core power loss comparison with different sized cores of the same material.



Large cores of the same material were found to have significantly higher losses when compared on the basis of mw/cm3.  This suggests that core loss for different core sizes cannot be calculated based on material specifications, which are usually taken using a "standard" core of about 2.5 cm outside diameter.

3. Core shape effect on power loss


Core losses were significantly lower for a core that was laminated.  The second core above has the same area, volume and weight as the first core, but it comprises 5 thinner laminations.


Core losses were significantly lower for a core that was hollowed out.  The second core has the same ID, OD and height as the first core.  Its area, volume and weight are lower, so higher losses may be expected at very low frequencies.


The four cores above all are the same weight and volume.  Cores 1, 2 and 3 have the same ID but cores 2 and 3 are stacked and have the same area, volume and weight as core 1. Core 4 has five times the area because it is wound with only one turn, but it has the same volume and weight as the others. 

The inductances of the four cores are very close to the same value, as are their other electrical properties except the core loss.  The multi-core stacks have significantly lower core loss.

4. Ferrites electrical properties

The electrical parameters (permittivity, permeability, and conductivity) of various ferrites were measured.  These must be known accurately to model the core performance successfully.

As an example, Finite Element Analysis (FAE) did not model the observed flux distribution very well using traditional parameters from data sheets.  Once the analysis was modified to use accurate parameters, the analysis was greatly improved.

5. Rectangular wave core loss tester

Part of the Phase II core loss program was developing an improved full-bridge rectangular wave driver for core loss testing.  The wave shape is determined by an arbitrary waveform generator under software control.  The voltage is controlled by a programmable power supply.  The time, voltage and current are measured using a high accuracy digital sampling oscilloscope and the parameters are exported to a spreadsheet for post processing and storage.  All of the software operations are written in Python.

PSMA Magnetics Committee

In addition to sponsoring these five core loss studies, the PSMA Magnetics Committee continues to be very active. They have organized 5 "Power Magnetics @ High Frequency" workshops in addition to conducting very successful APEC Industry Sessions each year.  They also presented two educational webinars as part of the "PSMA Basics of Magnetics for Switching Power Webinar Series" in early 2020. The committee meets about once a month by webconference and anyone interested is invited to participate. Contact the PSMA office at power@psma.com for more information.

New EU Appliance Regulations Add Complexity, Reform Product Labeling
Posted: 2020-9-28


Globally there are a plethora of energy efficiency regulations for almost anything that consumes energy. These regulations cover both operating mode efficiency as well as standby power consumption. Some of these energy efficiency regulations are mandatory and some such as Energy Star in the U.S. are voluntary and more marketing than regulatory in nature. And while there are challenges in meeting regulatory requirements in many regions, the European regulations are possibly the strictest in the world.

In Europe there are newer, updated regulations for energy efficiency targeting consumer white goods which we could see adopted as best practices globally. The new regulations also include changes in the labeling for appliances. In many cases, the product ratings used on labels have been simplified. The main purpose of these labeling changes is to allow consumers to make better purchasing decisions. Ultimately, the goal of these changes in energy efficiency and labeling requirements is to achieve energy efficiency objectives for the region.

Specifically, there is a mandate from the European Commission (EC) for the EU to achieve an improvement of 32.5% over 2018 energy consumption by the year 2030. The regulations are to reduce energy used in refrigerator products, dishwashers, washing machines and dryers, TVs and monitors, and lighting products.

These new European standards impose energy efficiency regulations on a product's standby, idle, and off modes of operation. Also there are new levels of energy consumption in the use mode. This is a complex calculation given in the details of each regulation.  

Many of the appliances have motors, which have raised concerns not only about their energy consumption but also regarding the noise they produce. As a result, the new EU regulations also contain emissions levels for audible noise. These noise limits may require the use of brushless dc motors (also known as electronically commutated motors or ECMs) to reduce the noise and increase energy efficiency in the operating mode.

This article presents highlights of Power Integrations' upcoming
webinar "EU Ecodesign and Energy Labeling Directives".

These changes in EU appliance regulations are the subject of an upcoming webinar by Power Integrations (PI) on "EU Ecodesign and Energy Labeling Directives," which will be presented by PI's David Chen on Tuesday, May 19, 2020 at 9:00 AM U.S. Pacific time (1600 UTC). This article highlights some of the key regulatory changes to be discussed in this webinar. To learn more, you can register for the webinar at PI's events page.

We would like to thank Power Integrations for sharing information from their webinar with How2Power Today in advance of the broadcast and for David Chen's input for this article. In addition, we'd also like to thank PI for the resources they have provided in the form of a free database and for their support of the PSMA Energy Efficiency database. 

Label Reform

Under the emerging regulatory changes, the label on each of the appliance products changes and there are new requirements for each product. For example, the labeling required in the old (EC) no 642/2009 and (EU) 1062/2010, which apply to TVs and monitors, changes in the new regulation. While the existing product ratings assign A, A+, A++, and A+++, the new rating system goes from A through G (more on this in the section on Displays).

Refrigeration Appliances

In this product category, the current regulation is (EU) 1060/2010, which offers product ratings from A+++ (most efficient) to G (least efficient). These ratings take into account energy consumption, storage volume, and a freezer compartment. In contrast, the newer standard (EU) 2019/2016 has a label with ratings ranging from A (most efficient) to G (least efficient). There is also a new sound emissions requirement which governs noise produced by the compressor for cooling.

The most effective means of energy savings is to keep ice from forming around the cooling coils. The removal of this ice is called a defrost cycle. This is described in the new standard.


The older regulation (EU) 1059/2010 has been replaced by (EU) 2019/2017. This new regulation takes into account standby energy, idle energy, and operating energy. The label for the product has changed with added icons to help the consumer to make an informed decision about energy use and acoustic noise emissions.

This regulation has a similar rating scale as the refrigerators, ranging from A to G. In addition, there's a figure of merit for the product's efficiency. The Energy Efficiency Index (EEI) is a ratio of two numbers, the ECO Program Energy Consumption (EPEC, measured in kWh/cycle) divided by the Standard Program Energy Consumption (SPEC, also measured in kWh/cycle):

The new regulation goes into greater detail on the measurement and the ratings.


Acoustic noise emission is one of the important consumer ratings. This requires the use of sound insulation and the use of an ECM.

Washing Machines

The current regulation (EU) 1061/2010 has been replaced with (EU) 2019/2014. Like the above appliances, the rating system goes from A (most efficient) to G (least efficient). The new rating is defined by the following equation:

where EW is the weighted energy consumption (kWh/cycle) and SCEW is the standard cycle energy consumption (kWh/cycle), and these terms are defined as:

where c is the rated capacity.

The new standard defines water consumption along with how well the water is removed from the clothes in the last spin cycle. This is important, as it affects the energy used for drying clothes. 


The European Union will lump TV sets and monitors together in the new regulation. 

The current regulation (EU) 1062/2010 for televisions sets forth the following conditions:

  • Labels scale from A+++ (most efficient) to D (least efficient).
  • Screen size is shown, but not resolution or high dynamic range (HDR).
  • Annual energy use shown on the label assumes the television is turned on for four hours/day, every day of the year.
  • It does not apply to computer monitors or to signage displays.

The new regulation (EU) 2019/2013 for electronic displays (TVs and monitors) imposes the following changes:

  • This regulation becomes effective on March 1, 2021, repealing the current regulation.
  • Labels are re-scaled from A (most efficient) to G (least efficient), with a lowering of the maximum power consumption limits (i.e. the new limits are more stringent).
  • New and old classes are not comparable, as the new scaling system is improved and better takes into account the screen area.
  • New labels will also show the efficiency of the product in HDR as well as information on the diagonal size of the display and the resolution.

Under the new regulation for electronic displays, there is a new energy efficiency calculation:

where A represents the viewing surface area in dm2, Pmeasured is the measured power in the on-mode in watts in the normal configuration and corr1 is a correction factor set as indicated in Table 3 (in the regulation).

The new label has the following format:

Figure. New label format for (EU) 2019/2013 for electronic displays.

Lighting Products

Lighting is a major user of energy. In many cases, LEDs have replaced incandescent, fluorescent and halogen lamps. The LED luminaire is a complete electric light fixture that distributes, filters and transforms light from one or more light sources to an open room or wall.
Many of these newer fixtures do not have replacement parts like the lamp or standard Edison A lamp. The fixture is complete with no replacement parts internal.

The current regulation (EU) 874/2012 for lighting products imposes the following conditions:

  • Ratings range from A++ (most efficient) to E (least efficient).
  • Luminaires have labels showing what lamps are suitable for use.

Under the new regulation (EU) 2019/2015 for light sources, the following changes take effect:

  • As of 25 December 2019, labeling of luminaires is no longer required.
  • This regulation goes into effect 1 September 2021, repealing the current regulation.
  • Labels are re-scaled from A (most efficient) to G (least efficient).
  • Labels will show energy consumption in kilowatt-hours (kWh) per 1000 hrs and include a QR-code link to more information in an online database.


The following is a list of the EU regulations for appliances.

  • (EU) 2019/2013    Electronic displays including TV and monitors
  • (EU) 2019/2014    Washing Machines
  • (EU) 2019/2015    Lighting
  • (EU) 2019/2016    Refrigerators
  • (EU) 2019/2017    Dishwashers

There are many details in each of the regulations and a Google search on each one will lead you to more-detailed information. It is beyond the scope of this article to provide the complete information on these requirements. However the two best practical resources on this subject are PI's Energy Efficiency Resources page (https://ac-dc.power.com/green-room/energy-efficiency-resources/) and the PSMA's Energy Efficiency database (https://www.psma.com/technical-forums/energy-management/database).

Many of the appliance types discussed above have standby power supplies. The new appliance regulations impose limits on the energy consumption in the standby, idle, and off modes. Therefore, it is in the best interest of engineers developing products in these markets to become aware of these regulations before the design phase to make sure the product development will meet or exceed the target requirements so that the product can be viable for sale in Europe and elsewhere. This along with EMC, safety and materials declarations requirements constitute most of what products will have to meet to be marketable.

Message from the PSMA Executive Committee
Posted: 2020-9-28


In the last quarter's PSMA newsletter, Mike Hayes, the new Chair of PSMA, offered a high-level outline of what PSMA and in particular the Executive Committee's goals are. It certainly is a challenging time with most working from home and every Conference and Exhibition cancelled or at best turned into a virtual event. Even with these challenges, the PSMA Executive Committee has been busy working on improving PSMA for the benefit of our membership and ecosystem at large.

As we prepare for next year's APEC in Phoenix, AZ, everyone is hard at work organizing an in-person event, while also planning for any eventualities. We certainly hope that the COVID pandemic of 2020 will be completely behind us and events will move forward in Phoenix. Given the lessons learned in 2020 we believe that should APEC once again be required to become virtual we will be prepared to make that transition faster and smoother than this year. Between now and then we are also working to advance our objectives.

Application Based Orientation

As the champion to move PSMA more towards an application-based orientation, I have worked with the PSMA Transportation Electronics, Energy Management and Capacitor Committees to create offerings that will begin that transition.

For example, the Capacitor Committee has formed a sub-committee, Energy Storage & Applications, which is working with the Energy Management Committee to create an independent Industry Session for APEC2021 on Energy Storage. The expectation is that Energy Storage & Applications will eventually become its own Committee once critical mass is achieved. The goal will be to focus on the types of Energy Storage and methods to optimize the different technologies including everything from EV Car Battery or Fuel Cell Systems to Energy Harvesting from microwatts to megawatts.

Another activity that is now being worked on is a Webinar that will combine Transportation and Capacitors. This webinar will offer a process outlining critical parameters in choosing capacitors in Automotive applications. There will be separate Webinars for 12V, 48V and High Voltage (400V - 800V) transportation systems. The presenters will identify a needed capacitor, size it, and then evaluate the proper technology and specific component that should be chosen using product datasheets, and knowledge of the technologies.

Finally (for now), the Transportation Electronics Committee has dropped its reference to power (previously called Transportation Power Electronics) to allow inclusion of everything that supports Autonomous Vehicles. We believe this is a critical step to give PSMA and the Transportation Electronics Committee more exposure to the Vehicular Industry. We are working hard to help educate the engineers in the vehicle industry to the benefits and strengths of PSMA and value of membership (see IPC below). As can be seen from all of the above this also means a lot more interaction and synergies between the PSMA technical committees reflecting the need for technologies to be combined to better solve applications problems.

Engaging more with our industry and academic stakeholders

PSMA has presented in both the IFEC Conference (International Future Energy Challenge), and a Webinar with IPC titled - Automotive Electronics: Solutions to New Challenges. PSMA is a co-sponsor of IFEC and it was a privilege to present an overview of who and what PSMA is. Many attendees and participants of conferences never know details about the sponsoring organizations. The Executive Committee is working to change that, especially since we sponsor so many conferences in addition to APEC, by giving more detailed introductions at all of our events. The IPC Webinar was directed specifically to Automotive personnel. A quick survey showed that the majority of these Automotive engineers had never heard of PSMA or APEC. PSMA will continue participating in Automotive based activities to further our footprint in that industry.

The Executive Committee is always open to additional ideas and/or possible suggestions. I hope that by outlining some of our current activities, that I may have triggered an idea or two from you, the reader. I would look forward to hearing any feedback that you may have.

iNEMI Publishes Best Practices for Protecting the Reliability and Integrity of Electronic Equipment when Disinfecting for COVID-19
Posted: 2020-8-20

The International Electronics Manufacturing Initiative (iNEMI) today announced publication of “Recommended Best Practices for Protecting the Reliability and Integrity of Electronic Products and Assemblies when Disinfecting for SARSCoV- 2 (COVID-19).”

Developed by a team of experts from across the member organizations of the International Electronics Manufacturing Initiative (iNEMI), this document provides guidance on how to mitigate the possible detrimental impact of disinfecting procedures on electronic equipment and assemblies. Groups such as the U.S. EPA, CDC and the World Health Organization (WHO) have published general guidelines regarding cleaning and disinfecting for COVID-19, but none of these specifically address the impact of disinfectants and their application methods on electronic equipment and assemblies. Many commonly recommended disinfection substances and/or application methods could potentially cause failures in electronic equipment.

To develop these best practices, the iNEMI team reviewed key industry, government and technical sources. They also assessed the chemicals included in the U.S. EPA List N: Disinfectants for Use Against SARS-CoV-2 (COVID-19) and common application methods, identifying those substances that minimize the risk of negative impact on electronic equipment when applied in an appropriate manner. 

“With the COVID-19 crisis, several of our members have contacted iNEMI for guidance on how to mitigate the possible detrimental impact of disinfecting procedures on electronic equipment and assemblies,” said Marc Benowitz, iNEMI CEO. “There are guidelines from groups such as the U.S. EPA, CDC and the World Health Organization (WHO) regarding cleaning and disinfecting for COVID-19, but none of these address the impact of disinfectants and their application methods on electronic equipment and assemblies.” 

“Many commonly recommended disinfection substances and/or application methods could potentially cause failures in electronic equipment if the internal electronics were inadvertently exposed to them,” continued Benowitz. “This is an obvious concern for electronics manufacturers who are wanting to ensure the safety of their employees, supply chain partners and customers, while protecting the reliability and integrity of their products.”

Benowitz explains that, in response to this industry need, a team of experts from across iNEMI member organizations reviewed key industry, government and technical sources and assembled a best practices document. The team assessed the chemicals included in the U.S. EPA List N: Disinfectants for Use Against SARS-CoV-2 (COVID-19) and common application methods, identifying those substances that minimize the risk of negative impact on electronic equipment when applied in an appropriate manner.

An Engineer's Guide to using Google by Chuck Mullett
Posted: 2005-8-23

Years ago we had to surround ourselves with printed reference material to provide the data on components used in our designs and applications papers to help in their use. Many of these were free, but some others cost over $100 each and became obsolete almost as fast as we obtained them. Today, the picture has changed dramatically. Most of this information is available at no cost through the Internet; the amount of information is so huge that the new challenge is sorting it out. When the semiconductor committee of PSMA began to study the problem of helping engineers find the information needed, the change in the way we do our jobs became blatantly obvious. Even this task has been made easier, because of help from the Internet.

Here is our conclusion: Google is perhaps the most advanced search engine in the world at this time. Surprisingly, it’s not just for lay people who are looking for new recipes or ways to remodel their bedrooms. Its capability to provide us with the sophisticated technical help we need is astounding. It has the capacity to improve its performance, on its own, as it is used. Our job in helping our members and others in the industry has been reduced from one of searching, rating and cataloging materials to one of simply providing a few hints about using Google. We suggest you try it for yourself, get familiar with its capability, and use it the next time you need information. Here are some examples for you to try:

1. Go to Google.com and type in power factor correction. Our result was that 2,190,000 references were retrieved in 0.23 seconds. Now, type in “power factor correction” and see the difference. We got 155,000 references in about the same amount of time. What is even more amazing is that the references were valid! Even in the first case---we looked through the first 120 on the list, and didn’t find even one irrelevant citing.

2. Try “mag amp” and retrieve 8,870 references. All were valid until we got down to the 29th one on the list, which referred to a slow-release garden fertilizer. 28 out of 29 is a validity score of 96.6%---not bad for software!!!

In Example 1 we saw the difference of enclosing the phrase in quotation marks. Doing so causes the search engine to look for precisely that phrase. Without this, the search engine will find hits on each of the words individually, inviting irrelevant references.

To the right of the search window on the home page you will find “Advanced Search.” Clicking on it will produce a page full of easy-to-use tricks to improve the search, including “Advanced Search Tips” on the top line of the page. This gives even more useful information to produce more effective results. Google is so easy that if you’ll spend only 5 minutes with it, you’ll be producing better results than you can find in a world-class library, without leaving your desk. Try it first, then try other search engines. We did this, and found a plethora of irrelevant “hits.” We invite your comments.
