Abstract
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.
Claims22
An apparatus for adding encapsulant material to a component attached to a substrate, comprising:
- an injector having an injecting outlet with an injecting tip through which encapsulant material is injected to a process area on the substrate and an air inlet with an inlet tip through which air is drawn from a process area on the substrate;
- a fixture in communication with the injecting outlet and the air inlet, the fixture including a receptacle for receiving the substrate and a gasket capable of forming a seal around at least a portion of the injecting outlet and vacuum outlet;
- 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 the process area on the substrate, at least the injecting tip and the inlet tip of the injector project through the substantially taut film to the process area.
An apparatus for adding encapsulant material to a component attached to a substrate, the substrate having a sheet of film covering a process area on the substrate, comprising:
- an injector having an injecting outlet with an injecting tip through which encapsulant material is injected to a process area on the substrate and an air inlet with an inlet tip through which air is drawn from a process area on the substrate;
- a fixture in communication with the injecting outlet and the air inlet, the fixture including a receptacle for receiving the substrate and a gasket capable of forming a seal around at least a portion of the injecting outlet and vacuum outlet, the fixture structured and arranged so that when the injector is in a position for dispensing encapsulant to the process area on the substrate, at least the injecting tip and the inlet tip of the injector project through the film on the substrate to the process area.
An apparatus for adding encapsulant material to a component attached to a substrate, comprising:
- a means for injecting encapsulant material to a process area on the substrate, the injecting means including an outlet for dispensing encapsulant material to a process area on the substrate and an inlet for drawing air from a process area on the substrate;
- a means for holding the substrate while encapsulant material is added, the holding means in communication with the injecting means;
- a means for sealing forming a seal around at least a portion of the outlet and inlet of the injecting means;
- and
- a means for forming a barrier between the holding means and the injecting means, the barrier means preventing encapsulant material from contaminating the receiving means and areas of the substrate outside of the process area and permitting the outlet and the inlet to access the process area of the substrate.
An apparatus for adding encapsulant material to a component attached to a substrate, the substrate having a sheet of film covering a process area on the substrate, comprising:
- a means for injecting comprising an outlet through which encapsulant material is dispensed to a process area on the substrate and an inlet through which air is drawn from a process area on the substrate;
- a means for holding in communication with the outlet and inlet of the injecting means, the holding means holding the substrate while encapsulant material is added and permitting the inlet and outlet of the process means to pass through the film disposed on the substrate to the process area;
- and
- a means for sealing disposed between the injecting means and the holding means, the sealing means forming a seal around at least a portion of the outlet and inlet of the injector means.
