1320mm Width Electrodeposited Copper Foil Sheet Shielding SGS
APPLICATION & SPECIFICATION
Electrodeposited copper foil TRZA-HTE (IPC-4562/3 Cu-E3) is high quality electrodeposited copper foil with zinc coating and low profile, which has higher elongation at high temperatures as per IPC-4562 requirements. Zinc coating allows it to be used for the fabrication of rigid CCL & MLB with higher lamination temperature (high Tg FR-4, FR-5, PTFE).

Application Of copper foil
Copper is great material of shielded signal .Widely used for rf cage /MRI room installations,building roof to protect out of oxidizition .
There are two main installation ways of RF cage building .
First option :
ED copper foil 1320mm -basic step- Make Wooden Panel +Put copper foil Covered wooden frame
+assemle copper foil wooden panel together.
Finished RF shielded cage as below:
Second option :
RA copper foil 600mm- basic step -Make bending edges of copper sheet
+Fix sheets on wood walls +welding edges of 2 pcs sheets together.
Finished RF shielded cage as below:
