Abstract
A system and method for reworking a flip chip includes use of a mill to remove an old flip chip, and a pick-and-place device for putting a new flip chip in place at the same location. The process may be automated, with the removal and the placement occurring sequentially without need for operator intervention. Other devices and processes may be part of the system/machine and process, for example cleaning following the milling, fluxing prior to the placement, and heating to cause solder reflow, to secure the new flip chip in place. Underfill may be employed to make for a more mechanically robust mounting of the new flip chip.
