  • The Difference between RA Copper and ED Copper

    The Difference between RA Copper and ED Copper

    We are often asked about flexibility. Of course, why else would you require a “flex” board? “Will the flex board crack if use ED copper on it?’’ Within this article we would like to investigate two different materials (ED-Electrodeposited and RA-rolled-annealed) and observe their impact on circui...
