摘要:
In an electrical connection to an electrical component in a disk drive suspension, an electrical lead is adhered to a component using conductive adhesive and is also mechanically pressed up against the component using a bias mechanism. The bias mechanism may be a spring finger that is welded to the suspension, or it may be a stainless steel finger that is formed integrally with the trace gimbal assembly. The resulting bias force that presses the contact against the component surface reduces the small failure rate that can occur when the conductive adhesive separates from the component's surface as a result of stress such as induced by thermal cycling.
