Abstract
In a lead frame conveying method and apparatus used in, for instance, a wire bonding machine, a detection of the leading end of a lead frame supplied from a lead frame magazine and a positioning of the lead frame on a lead frame path are executed by a positioning sensor which is installed in the vicinity of a bonding position; and after the positioning, the lead frame is chucked by feeding claws so that a first bonding portion on the lead frame is conveyed by the feeding claws to the bonding position, thus avoiding use of the end surfaces of the feeding claws during the execution of positioning of the lead frame.
