TechNet,
I am designing FR4 based components with copper wire-wound magnetic cores.
I will have exposed copper on the wire after assembly. My customers will
then reflow my assembly on to their boards using whatever flux they pick.
Is the exposed copper a problem and gross leak check the cover or should I
open mouse holes in the cover and not worry about copper corrosion and the
environment?
Feedback would be much appreciated.
Frank
