| 摘要 |
<p>A wire (6) made of aluminium or an aluminium alloy is passed through a capillary (5) and a first spark discharge is produced in a protective gas atmosphere between two auxiliary electrodes (12, 13). As a result of this the protective gas is ionised to form a plasma having such a low resistance that a spark discharge takes place between an electrode (11) and the wire (6) at a voltage of between 25V and 200V. Thus a ball is formed at the end of the wire which is then bonded between an electronic microcircuit (17) and a contact area (18) using the capillary. <IMAGE></p> |
