Webduring reflow. Package warpage during board assembly can cause the package terminals (solder balls) to have open or short circuit connections after reflow soldering. Warpage is largely driven by the coefficient of thermal expansion (CTE) mismatch between the constituent materials of the BGA package and can also be affected by moisture absorption.
