METHOD FOR FORMING IDENTIFICATION CODE

摘要

PROBLEM TO BE SOLVED: To provide a method for forming an identification code which can shorten time required to identify a failure wire bonding machine.

SOLUTION: A chip 110 having a plurality of bonding pads 111 is installed in a loading body 120 having a plurality of fingers 121. One binary system code reference line 130 is set on the loading body 120 to divide a finger 121 group into a first code area 122 and a second code area 123 by the binary system code reference linea 130. A bonding wire 140 group electrically connecting the bonding pad 111 group and the finger 121 group by a wire bonding method is jointed to any of the first code area 122 or the second code area 123 of the finger 121 group to configure the identification code of the wire bonding machine. According to such the method, the failure wire bonding machine can swiftly be traced by the identification code.
