Abstract
A method and apparatus is provided for transporting circuit boards in a screen printer. In embodiments of the present invention, a transportation system is provided for a printer that prints material on a substrate. The transportation system has the ability to independently move substrates from one position to another within the printer without moving other substrates contained within the transportation system. In one embodiment, the transportation system includes a conveyor system and a plurality of lifters that lift substrates off of the conveyor system to prevent at least one substrate from moving when other substrates are moved by the conveyor system. In another embodiment, the transportation system includes a conveyor system and a plurality of retractable pins, that are individually controllable to be raised above the conveyor system to contact at least one substrate on the conveyor system and prevent the substrate from moving when other substrates are moved by the conveyor system.
