Abstract
A high voltage transformer for a video display apparatus includes a bobbin-wound tertiary winding. The bobbin incorporates integral nonmetallic terminal posts about which the winding segment wire is wound and terminated. The winding segments are interconnected by electrical components. The component leads incorporate a solder coating and are flattened to provide a large bonding area with the wire on the terminal posts. The component lead overlays the winding segment wire and is joined thereto by a fusion bonding process. The fusion bonding removes the wire insulations and melts the component lead solder coating to form a reflow solder joint.
