FLX2011-MK now comes with with a dual dispensers. One, a jet valve dispenser, for 0603 or smaller surface mount components and LEDs on flexible circuits, is said to quickly and accurately dispenses small glue dots, and is contactless. Also has Archimedean screw type for dispensing solder paste or conductive adhesives; or time/pressure dispenser, Piezoflow valve or jet valve, depending on the specific application.

Assembly head features optical centering system that can align SMD components, LEDs and metal domes, permitting flexible circuit production all on one system. Foils are held in position by a vacuum table. Working area is 500 x 300 mm; support area is 800 x 300 mm. Smaller foils can be clustered and be produced like a single foil. Integrated vision system automatically finds reference marks and corrects offset and distortion.
