Abstract:
1. A method of bonding a wire between a first bonding location and a second bonding location, the method comprising the steps of: bonding a first end of a wire to a first bonding location using a wire bonding tool to form a first wire bond; forming a fold of wire on top of, and in contact with, the first wire bond such that the fold of wire includes (1) a first portion extending from the first wire bond in a first direction, (2) a second portion extending in a second direction substantially opposite and substantially parallel to the first direction; lowering the wire bonding tool in a direction towards the first wire bond immediately after the forming step, the lowering step being interrupted prior to the wire bonding tool contacting the first wire bond such that the bonding tool does not bond the fold of wire to the first wire bond; and bonding a second end of the wire to a second bonding location.
