64 SMT Magazine • April 2015 gained above indicate that reaching deposit specifications becomes a game of give and take; smaller deposits introduce slightly larger posi- tioning uncertainty, while increased position- ing accuracy demands slightly larger deposits. The game will be won by the combination that ensures process quality. SMT references 1.
