Why convert from BGA to CGA?

Area array packaging technology has taken the electronics industry by storm. Ball Grid Array (BGA) components provide a huge increase in available interconnects without the troubles associated with bent leads. However, these new components bring with them serious issues related to board-level reliability at extreme temperatures as seen in industrial, military, and space environments. Column Grid Array (CGA) is the solution to these problems.
