The present invention provides a method and apparatus for dispensing onto a substrate. In one embodiment, the apparatus includes an injector having an injecting outlet and an air inlet, a fixture for receiving a substrate in communication with the injecting outlet and the air inlet and having a gasket forming a seal around the injecting outlet and air inlet, and a sheet of substantially taut film disposed between the injector and a substrate placed in the receptacle of the fixture such that, when the injector is in a position for dispensing encapsulant to a process area on the substrate, at least the injectng tip and the inlet tip of the injector project through the substantially taut film to the process area.

Conveyorized vacuum injection system

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.

A method and apparatus for measuring and controlling the size of drops of viscous material dispensed from a dispensing system. A dispensing apparatus in accordance with embodiments of the present invention includes a housing, a dispenser that dispenses a quantity of the viscous material, a measuring apparatus having a bottom plate to receive the viscous material, a top plate that is positioned over the bottom plate after the viscous material has been dispensed, and a compressing apparatus that compresses the material between the top and bottom plates. The dispensing apparatus further includes a viewing system that views the compressed material to determine the quantity of material dispensed by the dispenser. In one embodiment, the dispensing apparatus includes a controller that controls the quantity of viscous material dispensed based on the quantity of material determined by the viewing system.
