Claim 12:
13. The method according to claim 12, wherein the preparation of PCB further comprises:
forming a transformer primary coil on a first PCB layer to construct the transformer primary winding;
forming a transformer secondary coil on a second PCB layer to construct the transformer secondary winding;
disposing the first PCB layer adjacent to second PCB layer such that the transformer primary coil is magnetically coupled with the transformer secondary coil to form a transformer layer assembly;
forming a coupler primary coil on a third PCB layer to construct the coupler primary winding;
forming a coupler secondary coil on a fourth PCB layer to construct the coupler secondary winding; and
disposing the third PCB layer adjacent to the fourth PCB layer such that the coupler primary coil is magnetically coupled with the coupler secondary coil to form a coupler layer assembly.
