Column Grid Array: The Solution to BGA Reliability Problems
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
wonderful 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.
In this year’s Military, Aerospace, Space, and Homeland Security (MASH):
Packaging Issues & Applications Workshop, Six Sigma presented a paper on the
conversion of BGA components to CGA. In the paper, data was presented which
demonstrates the considerable reliability improvements when using solder
columns. In addition, the significant advantages of the reinforced solder
columns were also presented.
