Electromagnetic waves and radio frequencies can have a major impact on a variety of electronic devices. Everyday items like cell phones and specialty items like heart monitors can run into major problems if signals are hit with frequency interference.

Tech Etch specializes in EMI and RFI shielding products to help clients control the level of frequency interference between devices and device parts. We can work closely with any company to design and manufacture the parts they need for their products.

What causes EMI and RFI?

The vast majority of today’s electrical devices send out signals or radiation in some form. These waves can have different wavelengths and not affect one another, but oftentimes, some of these waves will affect the function of a electronic device. Fuzzy phone calls, pixelated video, and sudden restarts can all be caused by EMI and RFI.

Proper shielding products can help stop these issues. Tech Etch develops and manufactures EMI and RFI shielding products, working side by side with companies to ensure they get the shielding items they need for their products.

How can EMI and RFI affect a Device?

EMI and RFI are serious problems that grow as technology increases. Many companies strive to put out new products throughout the year, improving upon the latest model. More devices are doing more things than ever before and this includes sending out more signals. As these signals flow from place to place, they can interfere with one another and cause disruptions. From bad cell phone reception to the failure of a medical device, the consequences of interference vary widely.

EMI and RFI shielding helps alleviate the chances of serious problems with electronic devices. Shielding products dissipate the signals without stopping them from reaching their destination. That way, the devices can work as they are intended without much risk of causing trouble for other devices or other parts of the same device.

How do Shielding Products Protect Against EMI and RFI?

Shielding products are designed alongside the design of the electronic device. Designers must know which parts of their devices will emit signals and radiation and consider how to filter these effectively.

Shielding products will absorb or reflect waves, directing them elsewhere and allowing for better signals between the device’s many parts. Many are mounted to the printable circuit board of a device for maximum effectiveness. Certain materials and types of metals are better than others for absorbing or redirecting signals and radiation.

When a company needs shielding products for their devices, it’s essential to work with experienced professionals in the field. Tech Etch has spent decades testing shielding products and making adjustments to better understand what works best.

What kind of shielding products can help?

Choosing the right shielding product for an electronic device requires many considerations. Type of shield materials, frequency and SE per EMC compliance standards, space available within the device, and much more must be considered. At Tech Etch, we offer a wide array of EMI and RFI shielding products. Just a few of our offerings include:
