Working principle of conductive cloth of shielding box parts

Author:admin   AddTime:2021-05-05

The shielding box is a metal body made of various shapes of conductive or magnetic materials, which limits the electromagnetic ability to a certain space and is used to suppress radiation interference. And deal with the conduction and radiation, so as to realize the equipment that provides a non-interference test environment for the wireless communication equipment under test.

The conductive cloth of the shielding box is covered with a silver-plated woven fabric on the foam plastic to form a soft cushion, which takes up most of the loose space. It is mainly for civilian use and is suitable for foam cushion cabinets and door panels. Fiber cloth (generally commonly used polyester fiber cloth) is pre-treated and then electroplated metal plating is applied to make it have metallic characteristics and become conductive fiber cloth. It can be divided into: nickel-plated conductive cloth, gold-plated conductive cloth, carbon-plated conductive cloth, Aluminum foil fiber composite cloth. The appearance is distinguished by plain weave and grid.



The structure of shielding box conductive cloth

The conductive cloth material is on the polyester fiber, first electroplated with metallic nickel, then coated with a high-conductivity copper layer on the nickel, and then electroplated on the copper layer with an anti-oxidation machine and anti-corrosion nickel metal, which is provided by a combination of copper and nickel It has excellent conductivity and good electromagnetic shielding effect, and the shielding range is 100K-3GHz.
