  • Method for setting conveying data for a lead frame
    Patent number: 6141599
    Abstract: A method for setting data for conveying a lead frame having a plurality of islands thereon to and from a bonding position of a bonding apparatus including feeding a lead frame so that the first island on the lead frame is positioned at the bonding position and the cross-hairs of a television monitor are aligned with an arbitrary position on the first island, storing the amount of feeding of the lead frame in a data memory, feeding the lead frame next so that the last island on the lead frame is positioned at the bonding position, aligning an arbitrary position on the last island which corresponds to the arbitrary position on the first island with the cross-hairs of the television camera and storing the amount of feeding of the lead frame in the data memory.

  • Lead frame conveying method and conveying apparatus
    Patent number: 5975835
    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.
