Method of and device for packaging electronic components thus packaged
View Patent ↗The invention relates to a method of packaging an electronic component such as semiconductor device, where by the component is positioned in a cavity of a foil by tweezers and is supported by means of a further foil which is attached to the foil at one side thereof. According to an example embodiment, the component is first placed into the cavity of the foil by the tweezers, and only after that is the further foil positioned adjacent thereto and attached to the foil. The tweezers are moved through the foil to pick up the component, hold it, and move it into the cavity. A feature of this embodiment is that the component may be temporarily supported by a supporting means after being positioned in the cavity and before being attached to the further foil, and the foil with the component is moved in a longitudinal direction (L) of the foil.
1. A method of packaging an electronic component whereby the component is positioned in a cavity of a foil by a pair of tweezers and is supported or retained by a further foil which is attached to the foil at one side thereof
wherein first the component is positioned in the cavity in the foil by means of the tweezers, and only then is the further foil attached to the foil;
wherein after positioning of the component in the cavity and before providing of the further foil, the foil with the component therein is displaced in a longitudinal direction (L) of the foil, during which the component is supported by supporting means which are present close to the foil at that side thereof to which the further foil will be attached; and
wherein the supporting means comprise a furcate member.
2. The method as recited in claim 1 , wherein the component is moved into the cavity from a position below that side of the foil to which the further foil will be attached.
3. A method of packaging an electronic component whereby the component is positioned in a cavity of a foil by a pair of tweezers and is supported or retained by a further foil which is attached to the foil at one side thereof, characterized in that first the component is positioned in the cavity in the foil by means of the tweezers, and only then is the further foil attached to the foil; and
wherein the component is provided in the form of a two-dimensional array on an elastic membrane and is moved therefrom to within the cavity in the foil by means of an exclusively reciprocal movement of the tweezers.
4. The method as recited in claim 1 , wherein the tweezers are formed by two needles which are positioned on either side of the foil, and the component is moved to between said needles.
5. The method as recited in claim 4 , wherein one of the two needles has an obtuse end and the other one a sharp end.
6. The method as recited in claim 1 , wherein another foil is provided at a side of the foil which is situated opposite the side to which the further foil is attached.
7. The method as recited in claim 1 , wherein the further foil and, if present, the other foil are fastened to the foil by means of a roller, during which the other foil if present, is preferably fastened to the foil from a different lateral position of the foil than that from which the further foil is provided.
8. The method as recited in claim 1 , wherein the foil is strip-shaped and provided with an array of cavities, each designed for one or several electronic components, and with an array of holes designed for transport of the foil in the longitudinal direction (L) thereof.
9. The method as recited in claim 1 , wherein a semiconductor device, or a discrete semiconductor device, is chosen as the electronic component.
