Wire tensioning apparatus

摘要

A device and method for providing tension and a reserve wire reservoir to a bonding wire for use with a bonding machine. The device includes an outlet port providing fluid under pressure, and a surface along which the pressurized fluid flows in a direction away from the outlet port such that the bonding wire follows a path along the surface and the pressurized fluid places a uni-directional tension on the bonding wire while maintaining a reserve portion of wire in a slack loop.
