Metal Shielding Products

FRD EMI Shielding products apply to the electronic equipment which encountered

EMI/RFI or ESD problems.

>There are wide range of products of different profiles to meet customer requirement.

>We recommend Beryllium copper, bronze or stainless steel as the material for most applications.

>Metal shielding products can not burn, not affected by ray, ultraviolet or ozone, which not only solve the shear force

>problem of other material, but also provide excellent shielding performance in the wide range frequency.

>Excellent spring of the material make the products easy to be re-used.

>Excellent mechanical properties make it suitable for multiple purposes.

>The metal shielding products can work well in a variety of circumstances(such as high temperature).We can provide various options for different coatings to ensure the compatibility with contact surfaces.

>The products are of less contact pressure, light and flexible for mounting.

>The products are of high thermal conductivity, pressure resistance, wear resistance and good plasticity.

>That is why R&D team prefer metal shielding products as the idea materials for design in Telecommunication, com-

puter, Portable electronic equipment, medical equipment and military instrumentation, etc.

Application

>We can provide variety of EMI shielding products with multiple mounting methods.This can be used for solving EMI

problem of for shielding room, cabin door, chassis, face board, socket PCB.IC, etc.

>EMI shielding products can be applied well to sliding friction situations.

>EMI shielding products can be used for various situations from small portable devices to large-scale shielding room.

Shielding compatibility

Emc

EM/RF shielding products are designed to hold or resist of electromagnetic interference, shielding reflection and ab-sorption of occasional radiation shielding.The higher the value of shielding attenuation, the more efficient hold or resistof unexpected electromagnetic interference.

Galvanic compatibility

Please refer to the following table in order to avoid Galvanic corrosion, adjacent groups of metals can be safely usedtogether.Better corrosion protection can be provided when selecting appropriate metals and surface plating in eachsingle group as below.For instance, if you choose BeCu in GroupⅢ, its plating can be selected in groupⅡ、Ⅲ、Ⅳ.We can provide over 20 kinds of plating for FRD?EMI metal shielding products to ensure the electrochemistrycompatibility.You can contact our engineer freely to get more information.
