lead movement, measured with respect to a datum, perpendicular to the top or bottom surfaces of a package that passes through the designed midpoint of the lead where the lead is attached to the package (for example, sidebrazed laminates) or where the lead exits the package body (for example, plastic dual inline packages). The movement is viewed from the side of the package, not the ends. [SEMATECH] Contrast lead-to-lead misalignment.
