What are the classifications of mobile phone shielding box design?

The box design of the mobile phone shielding box should ensure its conductivity continuity, and ensure the surface finish and contact tightness of the product. And what are the more widely used ones in the market?

In order to reduce the coupling interference voltage of the alternating electric field to the sensitive circuit, the mobile phone shielding box can be provided with a metal shield with good conductivity between the interference source and the sensitive circuit, and the metal shield can be grounded. The coupling interference voltage of the alternating electric field to the sensitive circuit depends on the product of the alternating electric field voltage, the coupling capacitance and the ground resistance of the metal shield. As long as the metal shield is well grounded, the coupling interference voltage of the alternating electric field to the sensitive circuit can be reduced. The electric field shielding is mainly based on reflection, so the thickness of the shielding body does not need to be too large, and the structural strength is the main consideration.



Conduction is a key part of the processing of the mobile phone shielding box. When the product is placed in the mobile phone shielding box for testing, it must communicate with the outside world through the interface, and the test instrument needs to be connected. When imported into the mobile phone shielding box, there is no shielding effect, and the isolation is extremely reduced. The test also cannot feedback accurate data.

Therefore, the key to the isolation of the mobile phone shielding box needs to be grasped on the interface processing, and the interface filtering methods are different for different tested product frequencies. The mobile phone shielding box adopts advanced casting technology, filtering and automatic control technology to make the performance more standard. It can effectively realize the communication with the computer and incorporate its standard instructions into the test program; it has multiple safety protections during operation. Function, can effectively prevent misoperation from causing damage to the operator and the product.
