ABSTRACT:
In a lead frame retainer mount used in, for example, wire bonding machines, tapered edges are formed on opposite ends of a frame retainer, and a frame retainer carrier which carries the frame retainer and tapered sections which engage with one of the tapered edges of the frame retainer are formed in the frame retainer holder. In addition, a fastening assembly which fastens the frame retainer to the frame retainer holder includes a handle mounted on the frame retainer holder and a clamp which is raised and lowered by a spring when the handle is turned so as to press against the other tapered edge of the frame retainer. Thus, replacement of the frame retainer can be accomplished very easily and in a short amount of time.
