What is CCGA: Column Grid Array (CCGA) provides a trusted solution for overcoming CTE mismatch (coefficient of thermal expansion) between large IC packages and printed circuit boards (PCB). Solder columns are compliant and absorb strain for critical applications typically found in the fields of military, aerospace and defense where significantly varying temperatures, high vibration and shock are present.
