While I don't believe this is feasible, I thought I would post this to
the forums on behalf of a member.
"We are looking at an application for a flexible printed circuit which
required some of the traces to carry 40 to 50 amps continuous current for
extended periods - say 5 to 6 hours. Is this something any has any
experience with. The charts I work from give a maximum of 27 amps for a
7mm wide trace on 6 oz copper and a 30 degree C temperature rise.
Is it even feasible to consider using a flex circuit in this case. I
would appreciate any input you may have on current carrying capacity of
copper conductors on flex circuits."
Thanks for any feedback.
Regards
