Abstract
The present invention provides a method and apparatus for dispensing materials onto a substrate. In one embodiment, a dispensing system includes a controller, a vacuum source in electrical communication with the controller, the vacuum source applying a vacuum to at least a portion of the substrate in response to an instruction from the controller, an injector in electrical communication with the controller, the injector comprising a valve in communication with a pressure source and a material port in communication with a material source, the valve permitting material from the material source to be dispensed onto a substrate in accordance with an instruction from the controller. In one embodiment, the dispensing system also includes a trap in communication with the vacuum source, where the trap substantially prevents excessive material dispensed by the injector from contacting the vacuum source.
