EMC-Devices functioning in Harmony!

EMC-Devices functioning in Harmony!

EMC-Devices functioning in Harmony!  All electronic devices produce electromagnetic emissions.  Electromagnetic emissions of every electronic device have to meet applicable standards.  Emissions outside of the standards interfere with function of other devices in the component.  Devices must be in compliance with EMC standards in order to be marketed.  EMC Compliance testing insures a harmonious shared electronic environment for optimal device performance. EMC-Devices functioning in Harmony!  EMC Compliance testing consists of three tests: Emissions- The Device Under Testing (DUT) is tested to...
Autonomous/Driver-Assisted Vehicles

Autonomous/Driver-Assisted Vehicles-Testing Galore!

Autonomous/Driver-Assisted Vehicles-Testing Galore!  Many of us feel that machines can't replace people.  This is especially true of the automotive driver seat!  People do not want to put their lives in the hands of a machine.  We've all dislike back seat drivers, but the thought of no driver is even scarier!  The reality of Partially Autonomous/Driver-Assisted vehicles is here.  Many cars already have AEB (Automatic Emergency Braking) systems.  My car has LKA (Lane Keeping Assist) and it's two years old!  I...
Internships-Preparing the New Workforce

Internships-Preparing the New Workforce!

Internships-Preparing the New Workforce!  Most of us must take an "internship" during our training.  An "Internship" is time away from a learning environment for "real world" application training!   I had to complete several "internships" while I was in dental school for practical training.  I learned to apply things I'd been learning about in "real" day-to-day clinical situations".  Witnessing real application of dentistry was much different than I believed it would be.  Experienced clinicians were full of methods that I never...
EMC Pre-Compliance Testing

EMC Pre-Compliance Testing-Home or Away?

EMC Pre-Compliance Testing-Home or Away?  EMC Testing is necessary during product development.  Pre-Compliance EMC Testing during development is more important.  Pre-Compliance EMC Testing prepares your device for Final EMC Compliance Testing!  Equipment for in house Pre-Compliance EMC testing can be purchased or rented.  Once the employees are trained in EMC testing, a "home game" is much easier all around than an "away game".  In-house testing also involves the development team, increasing their investment in product development.  Obviously, EMC Testing at...
Grounding Techniques

Grounding Techniques-Essential in People and Electronics!

Grounding Techniques-Essential in People and Electronics!  Grounding in electronics is the process of directing excess electricity to the ground via a wire.  Likewise, grounding in people is directing Earth's energy to people.  We all know people are truly "electronic devices" in a fashion.  We've all heard the term "grounded person" before.  Interestingly, that statement can be taken in several ways.  Many people practice Grounding/Earthing by being in direct contact with the earth.  In Health and Wellness areas, grounding allows the...
Corrosion

Rough Conditions Require Rugged Textiles!

Rough Conditions Require Rugged Textiles!  Conductive textiles are thin and lightweight.  Normally, these are excellent characteristics for many of their uses.  Metalized textiles are used in many electronic devices for shielding.  Electronic technology is becoming smaller all the time.  Shielding solutions must be flexible and adaptable to fit in tight spaces.  However, there are times that rugged characteristics are important.  Due to their fine structure, conductive textiles are usually not particularly durable.  The delicate nature of these shielding giants limits...
EMC Compliance Testing

EMC Compliance Testing-“Prep” your Product!

EMC Compliance Testing-"Prep" your Product!  EMC Compliance testing is often the final obstacle to product marketing.  It's important to prepare your product for this test!  Best Practice for Final EMC Compliance Testing is Pre-Compliance EMC Testing!  Pre-Compliance Testing at your own facility beginning early in development is great preparation!  This allows identification and mitigation of problems during every step of development.  Backtracking to find problems is time consuming and frustrating!  Products developed in this way will likely pass Final Compliance...
Supply Chain Slowdown

Supply Chain Slowdown? VTT can Help!

Supply Chain Slowdown? VTT can Help!  CNN Business reports that China is experiencing supply chain slowdown again.  This after global shipping had recently been recovering from the pandemic slowdown.  Shanghai is the world's largest container shipping port.  New Covid lockdowns in China affected Shanghai, resulting in worldwide supply chain delays.  Though the lockdowns are beginning to ease, the delays caused by them are now expected to last into the summer.  These new delays, combined with Russia's invasion of Ukraine, have...
Digital Privacy

Digital Privacy-How do we Achieve it?

Digital Privacy-How do we Achieve it?  Undoubtably, today's hackers are becoming more sophisticated.  The news brings stories daily about ransomware, security breaches, and identity theft.  How can we protect ourselves from these personal attacks?  Many of these crimes can be prevented logically.  Protecting electronic devices with updated antivirus programs is mandatory.  Common sense data security measures are important in daily situations.  These include not leaving a computer open when you leave the workspace, and not opening emails and links that...
Personal Shielding

Personal Shielding-RF/EMI Shielding!

Personal Shielding-RF/EMI Shielding!  We tend to think of RF/EMI Shielding in the electronics industry.  RF/EMI can affect the function of electronic devices.  Interference can reduce the operational efficiency of electronic devices.  Human beings are also electronic devices.  Many body systems are electronic in nature, potentially disrupted by RF/EMI.  We live in a world with ever-increasing RF/EMI.  Some of this RF/EMI is from nature.  Natural RF/EMI includes lightning, solar magnetic storms, the auroras, and the Earth's magnetic field.  The natural RF/EMI...
