<p>The device comprises a support (1) to which is fixed an induction loop (3) through which a high frequency alternating current passes. By displacing the support (1) or the printed circuit board (4) provided with contact pins (2) to be welded, a plurality of contact pins (2) is brought into the influence zone of the alternating magnetic field at the same time as the welding material (5) and the metallised passage holes (6) intended to be brought in contact with the pins. Owing to an appropriate arrangement of the induction loop (3), a well defined and uniform heating of the pins (2) and the contact zones is achieved. The device allows simultaneously a faultless welding of several contact pins (2) arranged into one or several rows and being part of connection strips fixed to printed circuit boards. </p> |
