C-5 chip carrier assembly, with the exception of the underside fluxing process, is a traditional pick and place operation that can be performed by chip shoot- ers, robots, or fine pitch machines (referred to as FPMs from here on). The specialized fluxing operation required for C-5 warrants the flexibility provided by robots who currently perform C-5 assembly. In addition to being a catalyst in the reflow process, flux also provides tackiness required to hold a C-5 carrier in position during transportation. A special tool consisting of a rotating disc with a levelling blade provides the required flux thickness for this process. The robotic C-5 assembly process currently requires 10.0 se&part of which 3.0 sets is used for fluxing. The current process uses reels or tray to feed carriers.
