Patent ID: 8044320

Claim:
A method for correcting a defective arrangement of solder bumps located in cavities of a mold comprising: searching, identifying and locating a missing solder bump missing from said arrangement, and subsequently replacing the missing solder bump with a prefabricated solder bump, wherein said replacing comprises removing the prefabricated solder bump from a deposit cavity arranged in an edge region of the mold and transporting the prefabricated solder bump to the cavity of the missing solder bump and inserting the prefabricated solder bump into said cavity, and wherein the prefabricated solder bump is released from the deposit cavity by a targeted energy beam being pointed to the deposit cavity from a bottom of the mold and is dosed such that material of the prefabricated solder bump melts at a border surface to the deposit cavity and the prefabricated solder bump separates from the deposit cavity and subsequently the separated prefabricated solder bump is lifted off the deposit cavity.
