Abstract
A transformer bobbin (2) having pins (24) extending therefrom is fabricated by winding connecting wire around the pins and pulling the wire until it breaks, then soldering the wire to the pins. The stresses imparted to the pins cause the pins to become mis-aligned when the bobbin material becomes softened during soldering. In order to correct this misalignment the pins are inserted, while the bobbin material is still soft, into holes (36) in a plate (34). The holes are aligned in the desired alignments of the pins and have at their upper ends (38) tapering profiles which contain the mis-aligned pins and guide them into their desired alignments. The pins are retained in the plate until the bobbin material has resolidified and the pins have become fixed in their desired alignments. During this time electrical continuity testing is performed on the soldered transformer.
