ABSTRACT:
A method of forming a surface mount transformer. The method comprises winding insulated wire around a magnetic core to form at least one secondary transformer coil, winding insulated wire around the magnetic core to form at least one primary transformer coil, attaching wire ends of the at least one primary coil to at least first and second vias of a printed circuit board (PCB), attaching wire ends of the at least one secondary coil to at least third and fourth vias of the PCB, affixing the coils and the magnetic core to the first side of the PCB, and attaching the coil wire ends flush to a surface of the vias on the second side of the PCB.
