Abstract
A printed circuit board assembly uses a conductive pattern that includes both firmly adherent conductors and controllably adherent conductors. The controllably adhering conductors are free to lift off the printed circuit board to relieve mechanical forces caused by thermal stresses at solder joints between the controllably adherent conductors and integrated circuit chips of the assembly.
