摘要:
A structure includes a substrate having a first region and a second region, the substrate also having a first surface and a second surface. Electrically conductive elements are exposed at the first surface within the second region. Wire bonds have bases bonded to respective ones of the conductive elements and ends remote from the substrate and remote from the bases. At least one of the wire bonds has a shape such that the wire bond defines an axis between the free end and the base thereof and such that the wire bond defines a plane. A bent portion of the at least one wire bond extends away from the axis within the plane. A dielectric encapsulation layer covers portions of the wire bonds such that unencapsulated portions, including the ends, of the wire bonds are defined by portions of the wire bonds that are uncovered by the encapsulation layer.

An electrical connection includes a first wire having one end stitch bonded to a surface, such as the lead finger of a lead frame or the connection pad of a substrate. A second wire has a first end attached to the surface on a first side of the first wire and a second end attached to the surface on a second, opposing side of the first wire. The second wire acts as a brace that prevents the first wire from lifting off of the surface. If necessary, a third wire can be added that, like the second wire, acts as a brace to prevent the first wire from lifting off of the surface.

A method for establishing an electrical connection between a first contact surface and a second contact surface, with a wire-bonding tool being used to provide a contact wire between the contact surfaces by bonding the contact wire to the first contact surface and subsequently leading it to the second contact surface, bonding it to the latter, and subsequently, separating it using the wire-bonding tool. After the contact wire has been separated from the second contact surface, the wire-bonding tool is used to provide the contact point with an additional contact securing element via the contact wire.
