EMI Shielding Materials
November 3rd, 2022Materials Used for EMI Shielding
There are many different types of RFI shields available in a variety of materials. Each has different properties and is therefore suitable for different uses.
When choosing the material for your EMI shielding, it’s important to look at the long-term costs of each option.
For example, more durable materials will require less frequent replacement. On the other hand, a heavy material could affect overall design and functionality.
This has led to the recent trend of using paints with shielding properties, as this is a lightweight solution, but the thinness of the resulting shield makes it less effective against higher frequencies (known as skin effect).
What to Consider When Selecting a Material for EMI/RFI Shields
The important factors when choosing a material for RFI shielding are:
Conductivity
Different devices need protection from different frequencies of electromagnetic waves, so the material must match the device’s intended use.
Solderability
This is important both in terms of the usefulness of the shield itself, and the cost of attaching it to the component or device.
Weight
Weight is an important factor in mobile devices which must be as lightweight as possible but can be an issue in any industry.
Corrosiveness
This is less important for shields being used in short-term products such as mobile phones but is critical in things like medical devices, where durability is essential.
Cost
Cost is most often a factor for mass-manufactured items but needs to be taken into account even in the development stage.
Material Options for EMI/RFI Shields
RFI/EMI shields must be conductive, so they are made from a variety of metals and alloys.
Copper is often included in the alloy because of its high conductivity as well as its natural resistance to corrosion which is an important factor in almost all RFI shield uses.
Gold and platinum are useful as RFI shield materials as they are non-reactive, as well as non-corrosive, making them perfect for use in medical devices such as pacemakers, where durability and safety are more important than cost.
Aluminum can be useful as a material for EMI shielding in certain situations and is popular due to its efficient strength-to-weight ratio, but it poses some serious challenges.
It is susceptible to corrosion and is difficult to solder, making it expensive to use.
Best Choice: Tin-Steel and Nickel Silver RF Shields
The most popular materials for RFI/EMI shields are tin-steel and nickel silver, because they offer the optimal cost-benefit balance.
Tin-steel (also known as tin-plated steel) is a popular material for RFI shielding because of its low cost.
Steel offers good protection again lower frequency interference making it useful as a material for shielding communication devices.
The tin plating ensures a high level of corrosion protection, giving the shields a satisfactory lifespan at a budget cost.
Tin-steel RFI shields are used for mobile phones and other mobile tech, as well as IoT devices, and are also used for smart cities and other “smart” technology.
One of the benefits of tin-steel is its high level of solderability, making it easy and cheap to work with.
Nickel silver alloy is used when a hard-wearing shield is needed, for example in life-and-death scenarios or to protect expensive equipment. It is the material of choice for MRI rooms and other medical devices, as well as aircraft and other vehicles.
Nickel silver blocks both electrical and magnetic waves and is anti-corrosive, making it suitable for use in a variety of conditions where durability is imperative.
EMI Shields to Suit Your Requirements
The drawn shields come in many different sizes. This exclusive production method creates seamless RFI/EMI shields which offer optimal protection for all types of devices and equipment.
All sizes can be manufactured in both tin-steel and nickel silver options, and all shields can be manufactured either in a single piece or as two pieces, a frame, and a cover.
The shields are also all suitable for use with SMT (surface mount technology) making them ideal for use in mass production.
Swagtron
June 19th, 2016How much fun can be packed into a 22-pound Hoverboard? Well, whether you weigh in at 40 or 220 pounds, there will be just about that much fun!

There’s absolutely no reason to be bored when you have the Swagtron Hoverboard to engage and constantly challenge your imagination and skills. So, let’s take a closer look at what you’ll be getting.
First things first
You’ve decided to get the Swagtron Hoverboard, so now it’s time to choose the color of Swagtron’s attractive acrylic body shell. You have choices: Black, gold, white, pink, blue or red. No matter the chassis color, when you push the power button, cool blue LED lights greet you.
This Hoverboard features a long-lasting, lithium ion battery package, which is housed in a tough aluminum shell. Swagtron is tops in its class of two wheel, hands free self-balancing electric scooters for safety. Why? Swagtron is the first one to get the respected UL2272 designation for electrical and fire safety, which is a great selling point for your folks.
Build your balance and strengthen your stance
Often, electric hoverboards are called self-balance scooters, and for good reason. Swagtron is the newest in this class of rideables. You can build up your balance skills as you control turns and start or stop by using changes in your balance. When you’re ready to ride, push the power button, put Swagtron into the learn mode and step onto to Swagtron’s slip-resistant foot pads.
To start, point your toes toward the ground, slightly shifting your weight forward. That will start the Swagtron’s quiet motor that propels you forward. Be sure not to lean your whole body forward to start. To turn left, you shift your weight onto your left leg; to turn right, you do the same for your right leg.
To stop, you shift your weight down onto your heels, again without leaning your whole body back. After a short practice in a safe place with your Hoverboard, these subtle movements will feel natural, and soon you won’t even have to think about them as you execute your moves. Swagtron users have called the hoverboard smooth, predictable and intuitive to ride.
Explore your environment
After you’ve practiced with your Swagtron around the house a bit, you’ll be ready to hit the road and see more of the world around you—and to let the world around see you, too!
You may want to start riding it on smooth pavement on a level surface, such as a path through a park. Save the more challenging, rough riding locations with dirt, gravel, potholes or hills until you’re more comfortable riding. You and your Swagtron hoverboard can venture out for about 12 miles on a charge, depending on the environment you’re riding in and other factors. You’ll notice when the Hoverboard starts to run out of battery. It begins to slow down gradually, so don’t worry that it will suddenly stop and dump you off. You’ll get adequate warning.
When you get back home, you can fully recharge it in an hour and be right back on the road again. If you happen to be out when it’s getting dark, your Swagtron Hoverboard has LED headlights. If you want even more attention when you go about town, personalize your Swagtron Hoverboard ride by getting some cool vinyl decals or stickers.
3D Printer for Home
January 17th, 2015So what’s the point of having a 3D printer in your home? Alright. You’ve heard about these printers that don’t just print paper – they print entire objects. And there’s a ton of hype behind them, saying that they’ll be just as revolutionary as the printing press was… or something like that.
But you’re probably wondering why. Why do people care so much? What can they do? We’re here to answer your questions in a quick, 3-minute post – after reading, you’ll know exactly why you’d want a 3D printer for home. Let’s get started.
You can print some legitimately (and awesome) useful stuff

Let’s start with the useful stuff. If you’ve ever watched an explanation video of a 3D printer, they’ve probably been printing some mundane stuff… like, lame as in solid blocks of plastic. The truth is that as long as you have a halfway decent printer, you can print a bunch of stuff that you use in your everyday life.
For example, you can print paper clips. That’s one of the most basic things to print. From there, it gets more and more exciting – as long as you have the materials, you can print some awesome stuff, such as…
- Dice for board games
- Mini furniture for your kid to use during play time
- Forks – and you can even print metal forks if you have a metal 3D printer for home
- Candle holders that look crazier than anything you could find in a store
- Pencil holders
- A stand for your iPad or iPhone
See where this is going? A 3D printer can make anything that’s made out of plastic.
And we know what you’re thinking – how on earth do you design something like this? Well, all we did to find the above items was do a search on Shapeways. It’s a site that allows you to buy 3D designs of almost anything – you just buy the design, upload it to your machine and let it rip.
You can get better at engineering as a whole
Assuming you want to, that is. On Shapeways, there’s a design for almost anything. And if you’re using your 3D printer at home, you probably don’t need anything too complicated.
But if engineering is your thing, then 3D printers are a great way to master your craft. You create the design in a program like AutoCAD, which you’ll probably be using for school anyways. As 3D printing gets more and more popular, you’ll be way ahead of your peers.
As long as you’re decent, you can sell your 3D designs
Once you get good enough, you can start designing stuff of your own that people actually want to buy. We mentioned Shapeways in this article, but there are a couple of other popular marketplaces – all you have to do is search for them. And there you have it – three reasons why you’d want to have a 3D printer for home. They’re not cheap, but at this point, they’re not that expensive, either. Pick one up for a couple hundred bucks and have fun!
Dental Implants
November 17th, 2013Dental implants are metallic artificial tooth roots designed to hold artificial teeth in place. They are designed to provide the ideal solution for missing teeth. Missing teeth do not only cause aesthetic and functionality problems, but may also affect confidence, self esteem and the quality of life. A dental implant can also provide the best alternative to removable prosthesis.
Types of Dental Implants
There are a variety of dental implants to choose from. However, there are basically two types to choose from:
– The more common of the two is the Endosseous (root-form) dental implant, which is embedded into the jawbone. It is made out of metal and comes in a threaded cylindrical form to allow bone integration.
– The second type is called the Subperiostal dental implant, which is designed to be fitted onto the bone. This is usually used in patients who have severe loss of bone mass to support an Endosseous dental implant.

Why People Choose To Have A Dental Implant
The usual choice for people with missing teeth is to go for removable dentures. Although this may be the fastest and most affordable option for some, it can be inconvenient in the long run. The use of dentures for the first time really affects speech. It also causes discomfort during eating. Even if a person has become used to using dentures, the removable prosthesis may have a possibility to fall off. These inconveniences can be eliminated by using dental implants instead.
The popularity of Endosseous dental implants is due to its firm attachment to the bone. It can stay in this state for many long years and maintenance is quite easy. In certain cases where there is a substantial deterioration of bone cells in the jaw, specialists can perform bone grafting to encourage the growth of bone tissue. As soon as the bone structure improves, a dental implant specialist can proceed with the Endosseous or root-form implantation.
The Benefits of Using Dental Implants
Enhanced Aesthetics — If a tooth is missing, it can affect a person’s smile. The dental implants can definitely help close the gaps in between the teeth and make a person smile better. Teeth gaps may also cause sagging in the facial tissues. As long as the gaps are filled, a person can look a lot younger.
Increased Confidence — People who have lots of teeth missing usually do not smile in public and may not want to meet up with people often because of their appearance. Dental Implants can definitely increase a person’s confidence by providing a better smile.
Prevents Jaw Bone Deterioration — The jawbone can start to deteriorate as a result of missing teeth. When the every gap in the bone is replaced with a dental implant as soon as possible, it can stay in better condition for longer periods of time.
Improves Functionality — Dental implants do not only help in the eating and chewing processes, but may also improve speech as well. People with gaps in their teeth usually do not speak as clearly as they should. As soon as the gaps are filled with dental implants, enunciation and pronunciation can be improved.
Alternatives
Not all people can have an Endosseous dental implant because there are several factors that have to be considered. Some of the most common factors include bone health and quality, smoking habits, oral hygiene, number of teeth missing, and the like. Nonetheless, there are certain alternatives.
People who have no teeth left can use complete dentures. They may also opt to have dental implants to secure their dentures firmly in place. People who have some teeth left may opt to go for a dental implant to support crowns and bridges.
If bone loss does not allow a dental implant to be installed, then surgeons may recommend bone grafting procedures. Bone cells are used to augment the area to be used for the dental implant. The procedure only takes an hour or more, but it may take months before the jawbone can become suitable for implantation.
