Conveyorized vacuum injection system

A dispensing system for dispensing material onto a substrate, the dispensing system comprising:

• 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;
• an injecting outlet through which the material source injects material to a process area on the substrate;
• and
• an air inlet through which the vacuum source draws air from a process area on the substrate, thereby drawing the injected material through the process area;
• wherein the injecting outlet and the air inlet are constructed and arranged to engage respective holes in a layer of cover material disposed adjacent to the process area of the substrate.
