Is This The Party To Whom I Am Speaking?

Alright. A old favorite quote from the phone operator (Lily Tomlin) on the 60's TV show “Laugh-In” may be a bit odd here. But even her brash remarks and jokes might be more preferable to a caller than a one-way (no doubling back) 5- or 6-step decision tree menu -- with an electronic voice posing multiple-choice questions.

So many businesses have them. Electro Technik Industries had one.

Of course, when you become totally familiar with such a system, using it is a breeze -- you’ve learned the prompts and know most of the direct lines or extensions anyway. What’s the problem? But first-time callers had no such familiarity. And first-time callers are often potential new customers. Overseas or international callers with English-language limitations were even more likely to make an unintended choice. Oops. Hang up. Call back. Really?

When multiple calls came in, one would sometimes roll over to a different ETI company’s open line. “Thank you for calling Hytronics.” “I was trying to contact Winatic.” “It’s OK. You’ve reached Winatic. Your call just came in on a different line.”

No more! The new ETI phone system is one of the most up-to-date available. Unlimited rollovers eliminate the (example) Hytronics/Winatic confusion. There’s still a menu, but you can double back if you need to. Automatic forwards to cell phones enable callers to reach their parties even if they’re away from the office.

Web-generated RFQs are very important. E-mail inquiries equally so. But our potential customers always want to speak to an ETI person, to get into the nitty gritty of their custom-component needs.

We listened to our rep and customer comments and we heard you. Moving forward -- a totally pleasant and rewarding experience when calling an ETI company.

ETI's Microwave Group Headed for Phoenix and MTT-S 2015

Coming soon: IEEE MTT-S 2015, Phoenix, AZ, May 17-22. Major focus of the huge event will be ETI's Microwave Group Booth #3341 -- of course!  The Microwave Group consists of Res-net Microwave, Nova Microwave, and Star Microwave.  

It's hard to believe that almost a year has passed since Microwave Week last June! Held in Tampa, FL, it was the first opportunity for many in our newly formed Microwave Group to get together, compare notes and products, and meet face-to-face with our inside sales people and support staff. 

On the final evening of MTT-S 2014, domestic and international sales representatives from Res-net, Star, and Nova Microwave (the latter two companies acquired by ETI within the previous twelve months) gathered with ETI staff at the Tampa Bay Museum of Art for dinner and a powerful presentation by Alen Fezuli covering the strengths of each company, exciting new products, and cross-selling opportunities that now exist as a result of this company grouping.

Acquaintances became friends; "contacts" became associates.

A reunion will take place in May. ETI folks and many many more will make the pilgrimage to Phoenix for IEEE MTT-S 2015. The show organization describes the event (in part) as “the premier conference covering basic technologies, from passive and active components to systems over a wide range of frequencies including VHF, UHF, RF, microwave, millimeter-wave, terahertz, and optical....”

The ETI Microwave Group will be there in force, once again.

Weed Out Counterfeits From Your Supply Chain.

We've heard so much about counterfeit components -- rejects, refurbs, and fake components sold as bona-fide first-quality parts --  it's almost as if the matter has become old news. It's difficult to believe that certain companies would go to such effort to do wrong, and continue to do wrong, as if there's no risk to getting caught.

Sprinkling, blacktopping, remarking. And what if a counterfeiters does get caught?  Names change to protect the guilty, and there's always a new customer looking for a bargain or an extra-fast delivery -- the gray market.

Years ago, it was intellectual property everyone was concerned about -- ramp up production (and reduce costs) by outsourcing offshore, enjoy the benefits for a brief time, and then marvel at the sudden appearance of look-alikes and copies -- IP down the river. These days, IP theft barely causes a stir compared to the huge problem of counterfeiting.

Perhaps you remember -- back  in 2011/2012 we learned about the U.S. Senate's finding that counterfeit electronic parts were installed or delivered to the U.S. military for several weapons systems, including the Army's Theatre High-Altitude Area Defense (THAAD) missile defense system, the Air Force's C-17 airplane and the Marine Corps' CH-46 helicopter.

Or, a bit further back, the FBI effort called "Operation Cisco Raider," which exposed the purchase of fake Cisco routers, switches, and cards by the U.S. Navy, the U.S. Marine Corps., the U.S. Air Force, the U.S. Federal Aviation Administration, and even the

FBI itself.

But counterfeiting has come long way since then. It's even bigger business now and growing, as indicated by the hi-tech lengths counterfeiters go to change and disguise their wares to sneak under X-ray inspection and other testing techniques.

And that's the true cost of counterfeiting -- the millions of dollars spent on policing and detection.

All of the companies in the ETI family are responsible manufacturers. We investigate the sources of our materials and QC the goods we receive from them. We manufacture in best faith -- to customer expectations -- without cutting corners or playing games. We're honest. IP is safe with us. We manufacture in the U.S. and also in Costa Rico to save costs near-offshore where we can. None of our scrap ends up in China to be recapped, blacktopped, remarked or resold.

We manage our supply chain very tightly, and make it easier for our customers to reliably manage theirs.

Electro Technik Industries has recently expanded its resistor selection to include thick-film resistors, made by HYMEG, which is now an ETI subsidiary. The new line includes:

HYMEG Precision Thick Film Axial Lead Resistors
HYMEG High Voltage Thick Film Axial Lead Resistors
HYMEG Precision High Voltage Plate Resistors & Dividers
HYMEG High Power Non-Inductive Resistors.

These new products share a common denominator -- they're all built using thick-film technology. The economical products are widely used where high resistance values are called for in relatively small-size packages, and where lower precision and higher temperature coefficients can be tolerated in the application. In effect, the thick-film manufacturing process used for HYMEG products results in lots of high-voltage/power handling capability for the real estate occupied, and a big bang for the buck. 

Another ETI subsidiary, TEPRO, manufactures precision wirewound resistors, chip resistors, disk resistors, Military RL-42 and other precision metal film resistors, and thin-film networks. Precision is the emphasis here, most often called for in lower voltage/power applications.

Choosing the most cost-effective resistor for an application tends to involve more than a component-to-component comparison of performance vs. size vs. cost. For example, it could cost less to use the resistor with superior overall performance specifications, because the need for compensating circuitry (and the cost of the associated components plus their assembly) may be eliminated. Furthermore, cost savings may also be achieved by concentrating precision in the resistors rather than in the active devices, because active devices have greater cost per marginal performance improvement than the resistors do.1

Our advice -- just tell one of our application engineers what you're trying to do and a bit about the circuit (727-536-7861). We now have a comprehensive selection of resistor types to choose from, so you can be sure to make the perfect choice.

Mil-Std-1553 -- Three Cheers!

How do you load up a military vehicle with instruments and complex electronic subsystems, ask them to talk to each other, to an onboard computer, and to operators, be “hard” in the face of EMI/RFI interference, be “fast” in response to data delivery requirements, be redundant and reliable even when damaged in combat situations...

...and save miles of wiring to boot?

The answer -- connect all these devices on a serial multiplex communications bus built to the requirements of Mil-Std-1553. That’s been the answer since about 1973, that is, two years before the last Apollo mission -- the Apollo-Suyuz docking event -- and almost 10 years before the advent of MS-DOS!

Raycom Electronics, an ETI subsidiary, manufactures QPL low power pulse transformers for Mil-Std-1553 applications. Hytronics, another ETI subsidiary, also builds versions of these transformers.

While Mil-Std-1553 hasn’t been the only answer for 40+ years, it may be the most ubiquitous and far reaching. It’s been designed into vehicles for space, air, and land -- both military and commercial. There’s a NATO version, a NASA version, and perhaps even a Russian version (a Wikipedia contributor explains it may be used on the Mig 35). We’re not sure if that’s true. But we know it’s used here (our thanks to http://www.milstd1553.com/applications/):

It seems that this old-school bus, and the devices connecting to it -- keep learning new tricks. Congratulations Mil-Std-1553. Carry on. Three cheers!

Gamechangers Come in Many Forms

Merriam Webster defines a game changer as "a newly introduced element or factor that changes an existing situation or activity in a significant way". First known use of "game changer" -- 1993.

            

In just the past month, at least two "gamechanger" examples have come about in the electronics world. One is a product developed by Henkel called Loctite GC 10 solder paste, which the company has touted as the first-ever temperature stable solder paste. Up to now PCB solder paste, with all of the various additives needed for optimum process soldering, required refrigeration from manufacturer to user and until use. It also had a brief shelf life, generally between 3-6 months.  Imagine the challenges involving a PCB manufacturing facility in Ecuador, India, or Indonesia, and the need for "fresh" solder paste that may or may not have remained refrigerated en route to delivery.

            

Yes. This new "temperature stable" solder paste may be an important game changer for the worldwide electronics manufacturing community.

            

A second "gamechanger" example is the recent development by Columbia University Engineering researchers of a technology that enables full-duplex radio integrated circuits (ICs) -- that can be implemented in nanoscale CMOS-- to enable simultaneous transmission and reception at the same frequency in a wireless radio, something never done before.  This, too, may be a bona fide gamechanger.     

Gamechangers in the development and manufacture of passive electronic components such as those produced by ETI companies sometimes (but, not often) come in the form of breakthroughs or discoveries. More often, our engineers are found working behind the scenes with customers who have need for our circuit design and application experience, in addition to our excellent products.

            

Our engineers' suggestions often improve performance, or, achieve the required performance for less cost (see example). We call it "Component Design For Manufacturing" (CDFM), a process by which our component design engineers work with customers' circuit design engineers to work through the circuit's requirements, tolerances, and alternatives (including variations in component design) to arrive at the most cost effective solution.

            

Is CDFM a gamechanger? Our customers might think so. To us, it's just a better way of doing business.

Mother Nature in Manufacturing

Sometimes it's difficult to understand why certain things we make work so poorly or so well. When they work poorly, we look for problems. When they work even better than expected, we hope we can repeat the good fortune over and over, unit after unit.

In other words, manufacturing repeatability can be a tricky thing, and replicating a process in a different place -- even with step-by-step cookbook instructions -- may produce disappointing end results.  

The reason may be that environment, in certain instances, has more to do than we know with the original success.  Whether the environment’s influence is upon materials, storage factors, curing -- all of these, or none of these, we simply may not know

. 

For example, we're all familiar with Stradivarius violins and their reputation of outstanding resonance and tonal quality. Despite the best modern day efforts, Stradivarius violins produced in the late 1700's and early 1800's are still considered unique -- the best violins ever. 

Many theories have attempted to explain why these instruments are so remarkable. Here's a recent one. Between 1400 and 1800 a “Little Ice Age” took place, which peaked between 1645 and 1715 during the coldest period called the "Maunder Minimum." Trees growing during that peak period showed the slowest growth rates of the entire last 500 years. 

In other words, Stradivarius and his contemporaries had access to and used especially dense spruce and other woods produced during this very cold period, without realizing their instruments would be unique because of Mother Nature.

Back to modern times, a wound film capacitor hardly compares in stature or importance to a Stradivarius violin in most people's minds. Also, Tucson, Arizona in 2015 is nothing like La Casa Nuziale, Italy in the 1700's. Oddly, however, certain capacitors built in Tucson may share a reason for excellence with those special violins -- the environment in which they are manufactured.

Tucson's consistently hot and dry conditions enable an ETI company, Arizona Capacitors, Inc., to make the very best wound film capacitors available today. So special are models of these capacitors that they are widely used in today's highest quality audio reproduction and amplification equipment. 

Because engineers can't be sure exactly "why" these audio capacitors work so well, they refuse to tinker at all with the manufacturing circumstances (location, environment, processes) in which they are built. And they’re certainly not seeking an offshore manufacturing source. 

After all, if the capacitors are helping amplify the music of a Stradivarius violin some evening, they have to do their job just right.
