Abstract
A thermo-compression tool incorproated in an assembly/disassembly system melts solder films of conductive leads of an electric circuit componet for bonding the conductive leads to pads of a circuit board, and nozzles blow high-temperature nitrogen gas to the conductive leads during the bonding work for preventing the solder films from oxidization.
