How to Select and Define the Right Shielded Box?

Choosing the wrong parameters can lead to inaccurate test results or wasted budget. As a source manufacturer, we recommend defining your custom solution through the following four steps:

01

Define the Test Frequency Band

Confirm the wireless operating frequency of your product, such as 2.4GHz Bluetooth, 5.8GHz Wi-Fi, or high-frequency millimeter wave. The frequency band determines absorber thickness and filter selection.

02

Evaluate Shielding Requirements

How strong is the electromagnetic background noise in the external environment? How many dB of leakage reduction do you expect inside the box? Production-line batch testing typically uses 65-70dB, while R&D laboratories often require >80dB.

03

Estimate Working Dimensions

In addition to the DUT size, include extra space for internal test fixtures, cylinders, and probe placement. We recommend increasing length, width, and height by at least 50mm-100mm beyond the actual product size.

04

List Interface Requirements

List all cables that need to enter from outside the box during testing, such as USB for power, RJ45 for data, and low-loss RF coaxial SMA/N interfaces for instruments.

Precision Manufacturing, Refined for Three Core Performance Advantages

1. Ultra-Wide Frequency Range and Strong Shielding Effectiveness

1. Ultra-Wide Frequency Range and Strong Shielding Effectiveness

Supports wideband testing from 100MHz to 12GHz, ensuring a clean wireless environment inside the box.

2. Rich, Highly Matched Low-Loss Interfaces

2. Rich, Highly Matched Low-Loss Interfaces

Provides data and power filter configurations to ensure stable, reliable signal transmission when cables enter and exit the box.

3. Multiple Actuation Methods and Mechanical Anti-Pinch Design

3. Multiple Actuation Methods and Mechanical Anti-Pinch Design

Supports manual, drawer-style, and pneumatic opening and closing, with configurable safety protection.
