Abstract: Integrated circuit chip attachment is described using a local heat source. In one example an interposer has a top side to connect to a silicon component and a bottom side to connect to a circuit board, the top side having a plurality of contact pads to electrically connect to the silicon component using solder. The interposer a plurality of heater traces having connection terminals. A removable control module attaches over the interposer and silicon component to conduct a current to the heater connection terminals to heat the heater traces, to melt a solder on the contact pads of the interposer and to form a solder joint between the component and the interposer.
