Abstract

Assembly 10 comprises a printed circuit board 11 having conductive land patterns on its two sides. A plurality of lead terminals 12 is joined by soldering to the rear conductive land pattern. Transformer core 13, wound with multifilar wires 14, is mounted and attached to the printed circuit board by plastic plug 15. The ends of wires 14 are split, cut, stripped and attached to the front conductive land pattern. Then assembly 10 is completed by encapsulation either inside casing 16 or by a transfer molding technique. This assembly can be obtained by using large sheets of printed circuit boards and large sheets of lead terminals, both cut into strips. After joining lead terminals to the conductive land patterns, elementary assemblies 10 are obtained by cutting.
