regression plane

A plane that (1) passes through the apex of the terminal that has the greatest perpendicular distance from the package substrate and (2) is parallel to the best-fit plane through the apexes of all terminals determined using the method of least squares.

NOTE The regression plane may be used to emulate the package coplanarity during reflow soldering at the point of surface mounting.
