A transducer horn for holding a tool, such as a capillary, for a wire bonder has a pair of resilient arms which flex to clamp about a tool placed in a passage between the arms. The adhesive is able to bind at very low surface free energy substrates, such as Xerographic prints contaminated by silicone fuser oil. Establishing the mapping includes using a set of charts where an individual chart encodes a mapping of a single face of the second polygonal mesh representation to a plurality of triangles of the first triangle mesh representation that the single face of the second mesh representation overlaps with parametrically. A fabric panel attached at one end to the housing has a second end wrapped about the tool and serves to lower the tool toward the pathway in an even and controlled manner before the tool leaves the fabric panel. The guide includes, but is not limited to a first guideway for moving the front end portion towards the top and a second guideway for moving the front end portion towards the bottom and the first and second guideway are formed spatially separated on the guide. The terminals are fixed to the upper insulating case by heat welding.
