Claim Text:
1. An apparatus comprising: a bridge board comprising a multilayer substrate having a plurality of conductive layers separated by insulation and having a length, a set of A-side contacts located near an end of the bridge board on a first side of an isolation boundary, the isolation boundary dividing the length, and a set of B-side contacts located on a second side of the isolation boundary near an opposite end of the bridge board, the set of B-side contacts being separated by a predetermined distance from the A-side contacts; the bridge board including one or more transformers, each transformer including an A-side winding connected to the A-side contacts and a B-side winding connected to the B-side contacts; each A-side winding being galvanically isolated from each B-side contact and each B-side winding; each B-side winding being galvanically isolated from each A-side contact and each A-side winding; each A-side and B-side winding being formed in a respective conductive layer of the bridge board and being located in a region providing space for a magnetic field coupling the A-side and B-side windings; the bridge board being constructed and arranged to span a separation distance between an external A-side circuit having a set of A-side terminals located in an A-side area on a printed circuit board (PCB) and an external B-side circuit having a set of B-side terminals located in a B-side area on a PCB, with the A-side contacts of the bridge board aligned and mated with respective ones of the A-side terminals and the B-side contacts of the bridge board aligned and mated with respective ones of the B-side terminals; the bridge board providing a galvanically isolated mechanism for connecting the external A-side circuit to the external B-side circuit.
