Conveyorized vacuum injection system

摘要

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.
