ED COPPER FOIL FOR CCL&PCB
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).
