Definitions
- Electronic component in particular SAW component working with surface acoustic waves, and method for producing this component.
- the present invention relates to an electronic component, in particular an SAW component working with surface acoustic waves, with a chip with a piezoelectric substrate, with electrically conductive structures arranged on the chip - interdigital transducers, connecting tracks and the like - with a base plate with external ones , with the electrically conductive structures of the chip contacted connection elements and with the hermetically sealed frame arranged on the base plate, within which the chip is arranged at a distance from the frame.
- the invention further relates to a method for producing this component.
- the present invention has set itself the task of creating a further miniaturized SAW component of the type mentioned and a less complex method for its production, while reducing the manufacturing costs.
- the invention proposes in an electronic component of the type mentioned at the outset that the space between the chip and the base plate is covered with a film, e.g. Plastic film, tightly enclosed is that the space between the frame and film with the film or with potting compound, e.g. Epoxy resin is filled and that the chip together with potting compound and frame by a coating of galvanic material, e.g. a CuNi alloy, the edge area of which rests tightly on the base plate.
- a film e.g. Plastic film
- potting compound e.g. Epoxy resin
- the relevant method for this suggests that the chip - except for the side surface facing the base plate - is encapsulated with a film which is pulled down at least to the base plate, that the space between the frame and the film is filled with sealing compound, that the film in its potting-free surface areas, e.g. is removed by means of plasma etching and that a coating of galvanic material is applied to the chip together with the potting compound.
- Dispensing with the protective film contributes to a considerable reduction in costs and to a reduction in the dimensions of the components.
- this 3 element due to its increased reliability, since when it is soldered onto the base plate, which is done using flip-chip technology, there is no risk that the solder balls or bumps, which are liquid in this state, can flow into free spaces or gaps as they do occur when the component is underfilled with potting compound, for example epoxy resin. This danger also does not exist when the component is soldered into the customer's circuit.
- Figures 1 to 3 show a partially sectioned and schematic representation of the manufacture of a component according to the invention.
- a support plate in particular ceramic plate, which can be separated into base plates 3, is provided, which, lined up on the support plate, carries self-contained frames 4, so-called solder frames, within which chips are spaced apart from the frames 2 are soldered in flip-chip technology with their electrically conductive structures to corresponding conductor tracks of the base plate.
- the chips 2 soldered in this way except for the side surface facing the base plate 3 — are encapsulated with a plastic film 5 or metal or composite film that is pulled down at least to the base plate 3.
- the film 5 is preferably guided in the space between the solder frame 4 and the chip 2 over the entire surface of the base plate 3 and solder frame 4. Possible, if advantageous in terms of production technology, the film 5 can also completely envelop the solder frame 4 and rest with its ends on the base plate 3.
- the space between the solder frame 4 and the film 5 is, if necessary, with 4
- Figures 1 to 3 show the individual manufacturing steps using only one OFB component.
- the production provides base plates (panels) of relatively large area with a multiplicity of chips which are arranged in rows and are each surrounded by frames, in particular solder frames.
