Design For Manufacture (DfM) Add-On for Altium Designer is free and factory-certified. Implements Sunstone’s manufacturing capabilities interactively inside Altium Designer. Is said to reduce costs by reducing design errors; reduced time by using existing rule decks instead of user-created versions; and simplify design processes by following a factory-certified rule deck.
