Things To Consider While Selecting And Configuring An RF Shield Box

Electronic devices accepting RF frequencies need accurate testing to ensure they perform effectively and meet regulatory requirements.

However, today the emission of RF and EM signals is everywhere, interfering with the testing and measurement of electronic devices. This makes device shielding from these frequencies crucial during testing.

But with so much to consider and look into, you might be wondering how to select the right RF Shield Box.

Selecting an RF Shield box for testing applications is a significant process that shouldn’t be taken lightly. To avoid any testing errors, having true knowledge of key considerations for selecting and configuring the RF Testing Enclosures is necessary.

And if you have been digging the internet in search of that, you’ve come to the right place.

In this blog, we will cover everything about the key considerations to select and configure the RF Shield box.

Top Tips While Selecting An RF Shield Box

1. Right Box Selection –

When selecting an RF shield box, it is essential to consider the type of testing you will be performing and the number of products you will be testing. There are three main types of shield boxes to choose from manual, pneumatic, and automated.

  • Manual RF Shield Boxes – These types of RF Shield boxes are generally small in size and easy to operate. They are ideal for research and development, testing, and other institutions. If you are only developing test samples and testing in small quantities, a manual shield box may be the best option for you.
  • Pneumatic RF Shield Boxes – These types of RF Shield boxes are large in size and ideal for testing mobile phones, notepads, and other corresponding size equipment. If you are testing large samples frequently, it is recommended to choose a pneumatic shield box.
  • Automated RF Shield Boxes – Automated shield boxes are used in a large-scale production line, particularly for small radio frequency modules. These types of RF Shield boxes are a popular choice in workshops for mass production, and they can be combined with other automated equipment to form an automated testing tool.

2. Shielding Effectiveness –

Another important consideration is the shielding effectiveness of an RF Shield box to ensure accurate testing of your electronic devices. The shielding effectiveness of your RF shield box should be high enough to block unwanted RF signals but not too high that it can affect the signals being tested.

3. Durable –

Your RF shield box needs to be durable to withstand repeated use. Moreover, the material used to manufacture the RF Shield box should be of high quality and resistant to any wear and tear caused during the testing process.

4. Ideal Shape & Size –

When selecting an RF shielding box, carefully choose the size of the product that you will be testing. To ensure your product fits correctly inside the box, measure its length, height, and width to determine the appropriate working size of the RF shielding box.

Next, for the shape of the RF Shielding box, there are different types of RF shield boxes available, from drawer type to chambers and more. So it’s important to choose the one that best fits your needs.

Key Considerations While Configuring An RF Shield Box

1. Power
RF Shielding is crucial for electronic device testing enclosures. Hence, conducted RF signals on the AC mains power cable must be filtered as they cross the enclosure wall to prevent any potential degradation in shielding isolation.

Our RF Shield box uses high-performance capacitors and low broadband inductors to provide greater decibel attenuation to any RF signals shown on the power cable.

2. Data
Electronic device testing contains a variety of data formats and connectors that includes USB, Ethernet, fiber optic, audio, video, and more.

And these different signals require different filtering and testing levels for proper isolation of the device. Here at RF Isolation, we offer a customizable range of RF Shielded Enclosures for diverse applications for higher-performance filtered interfaces and other custom-designed interfaces.

3. RF Signal
In RF signal testing, an RF connector is used to pass the enclosure wall and connect to the device inside and to the test system on the outside. A suitable RF connector is necessary for maintaining proper shielding from external signals.

4. Thermal
Inside the device testing enclosure, there is a closed area with very little airflow for convection cooling. This can cause heat buildup, so proper ventilation options should be done to remove excess heat from the enclosure.

Honeycomb-style ventilation can be used to allow excellent shielding isolation as well as airflow with little resistance. Make sure to consider if your device requires ventilation or not and configure it accordingly.
