摘要: According to one embodiment of the invention, a method for coupling electrical contacts is provided. The method includes providing an electronic component having a contact that is to be coupled to another contact. The method also includes forming, over the contact, a bonded ball having a downwardly sloping shoulder that extends from a point and ends at an edge of the shoulder. The downwardly sloping shoulder has an angle between 105-130 degrees from a first imaginary vertical line that intersects the point. The downwardly sloping shoulder does not have a structure that makes contact with the electronic component and also extends in an outward direction from a second imaginary vertical line intersecting the edge of the shoulder. The method also includes coupling the bonded ball to the another contact using a wire.
