With the development of high technology, many advanced technological products have been created. Shielding boxes have emerged during the development of these technologies, and today, there are many types of shielding boxes available. Next, editor Jiachen will introduce to you the specific functions and application scope of shielding boxes.

The shielding effect refers to the difference in signal values measured when the shielding box is open and when it is closed at a specific frequency band during product testing. The difference between these two values represents the shielding effect. The unit is dB (decibels), and the difference is a negative value. The smaller (more negative) this value is, the better the shielding performance of the box, the more effective the test shielding, and the more stable the product signal.

The RF testing process is often the most complex and influential step in the production line of wireless communication devices such as mobile phones, and it is often a bottleneck in the manufacturing process. An RF test station typically consists of test instruments, a shielding box, testing software, etc., and can be divided into calibration tests, comprehensive tests, antenna tests, and more.

Electromagnetic interference (EMI)/electromagnetic noise is a common challenge faced by the entire electronics industry today. In general, wireless communication products such as mobile phones, wireless network cards, wireless routers, wireless headsets, Bluetooth earphones, Wi-Fi, WiMax, data cards, and wireless communication devices such as walkie-talkies use RF shielding boxes/test shielding boxes to improve the testing environment. These are used during module testing and final product testing when applying RFID and other wireless communication modules.

Shenzhen Jiachen Technology Co., Ltd. is a high-tech enterprise established in 2004. It is one of the earliest domestic manufacturers specializing in the production of shielding test equipment for communication products. Currently, the company offers more than 600 product lines, including shielding equipment, acoustic devices, automated robot testing systems, and more. All product performance indicators have reached professional standards. If you're interested, you can learn more on our official website.
