Systems for assembling components on submounts and methods therefor
View Patent ↗A component assembly system is provided that includes a longitudinally elongated tape carrier, a longitudinally elongated submount carrier, and an assembly machine. A plurality of components may be attached to the tape carrier. The assembly machine is adapted to receiving the tape carrier, with the components attached thereto, and to receive the submount carrier. The assembly machine is further adapted to bring the tape carrier in close proximity to the submount carrier, and to attach the components to the submounts on the submount carrier.
1. A component assembly system, comprising:
a longitudinally elongated tape carrier;
a plurality of components attached to the tape carrier;
a longitudinally elongated submount carrier, the submount carrier including a plurality of connected submounts; and
an assembly machine that is adapted to receive the tape carrier, with the components attached thereto, and to receive the submount carrier, and is adapted to bring the tape carrier in close proximity to the submount carrier, and to attach the components to the connected submounts on the submount carrier.
2. The component assembly system of claim 1 , wherein the assembly machine is further adapted to detach the tape carrier from the components after the components are attached to the submounts on the submount carrier.
3. The component assembly system of claim 1 , wherein each of the submount carriers includes a component receiving portion that is adapted to receive at least one of the components, and the distance between the component receiving portions of at least two adjacent submounts is the same as the distance between at least two adjacent components on the tape carrier.
4. The component assembly system of claim 3 , wherein the component receiving portions of adjacent submounts are separated by the same distance as adjacent components on the tape carrier.
5. The component assembly system of claim 1 , wherein the components are attached to the tape carrier to form a pattern of at least two longitudinal columns of components.
6. The component assembly system of claim 1 , wherein the tape carrier includes an adhesive surface, and the components are attached to the adhesive surface.
7. The component assembly system of claim 6 , further comprising:
a protective cover on the adhesive surface of the tape carrier, and wherein the assembly machine is adapted to peel the protective cover away from the tape carrier before attaching the components to the submounts on the submount carrier.
8. The component assembly system of claim 1 , wherein the assembly machine is adapted to form an adhesive material between the submounts and the components.
9. The component assembly system of claim 8 , wherein:
the adhesive material is a glue, and the assembly machine is adapted to sufficiently cure the glue so that the components become more strongly attached to the submounts than to the tape carrier.
10. The component assembly system of claim 1 , wherein:
the assembly machine is adapted to form a solder material between the submounts and the components, and to at least partially melt the solder material so that the components attach to the submounts.
11. The component assembly system of claim 1 , wherein the assembly machine is adapted to provide a thermocompression bond between the components and the submounts.
12. The component assembly system of claim 1 , wherein each of the components is a light emitting diode die.
13. A method of assembling, comprising:
providing a longitudinally elongated tape carrier;
providing a plurality of components attached to the tape carrier;
providing a longitudinally elongated submount carrier, the submount carrier including a plurality of connected submounts;
moving the tape carrier longitudinally;
moving the submount carrier longitudinally;
sequentially aligning components on the tape carrier in close proximity to submounts on the submount carrier; and
attaching the components to the submounts on the submount carrier.
14. The method of claim 13 , further comprising detaching the tape carrier from the components, after the components are attached to the submounts on the submount carrier.
15. The method of claim 13 , further comprising:
forming a pattern of at least one longitudinal column of the components on the tape carrier;
forming a pattern of at least one longitudinal column of the submounts on the submount carrier;
aligning at least one component on the tape carrier with at least one submount on the submount carrier; and
advancing the tape carrier and the submount carrier along longitudinal paths through a contact zone, at least one of the components contacting at least one of the submounts within the contact zone.
