Abstract: A printed circuit board (PCB) for an ignition apparatus includes a connection interface. The connection interface includes a first hole, and a second hole that is smaller than the first hole. The second hole has a pad associated therewith that is electrically coupled to a conductive trace for connecting to a system connector. The first hole and the second hole are coupled by way of a channel. The first hole is sized so as to facilitate insertion of a winding end, while the second hole is configured to facilitate a soldering operation of the winding end to the pad. The channel width is less than the diameter of the winding end so that once the winding end is in the smaller hole, the channel provides, in-effect, a retaining feature until it can be soldered.
