Abstract
An upper member for inducting power in a coupler assembly having an electromagnet core is a subassembly of a top body member and a bottom body member which enclose a circuit substrate. The circuit substrate is disposed within a cavity between the top and bottom body members, and includes electrical components surface mounted on at least one surface of the circuit substrate. EMI/RFI shielding is formed by plating of at least the surfaces around the cavity surrounding the circuit substrate, and conductively joining the top and bottom body members completely surrounding the circuit substrate thereby protecting the electrical components from EMI/RFI interference.
